Environmental Chemistry And Technology: Catalysis For Advanced Biofuels

Multifunctional Catalysts for Efficient Biomass Valorization

Significant attention and research efforts of the scientific community have been dedicated to the efficient valorization of biomass-derived oxygenates to advanced biofuels and petrochemicals. Efficient conversion of simple biomass-derived building blocks, such as different furanics, aldehydes/ketones, acids/esters and phenolics, requires a cascade of multiple conversion steps including, for instance, C-C coupling, dehydration and hydrogenation reactions relying on multifunctional catalysts instead of a cascade of single-function catalysts. Thus, the main motivation of the project is to design efficient multifunctional catalysts for multicomponent mixtures of biomass-derived oxygenates.

Main objectives and role of postdoc:

  • Rational design of multifunctional catalysts
  • Synthesis of multifunctional catalysts
  • Characterization of multifunctional catalysts
  • Evaluation of multifunctional catalysts in the model reaction system including C-C coupling and (partial) hydrodeoxygenation
  • Interpreting the structure-activity relationships as a way to improve the catalyst design

Planned activities:

  • Design and synthesis of multifunctional heterogeneous catalysts
  • Detailed characterization of synthesized catalysts
  • Activity, selectivity and stability testing of the synthesized catalysts
  • Analysis of the catalyst synthesis-structure-properties and structure-properties-activity-selectivity relationships
  • Research project proposal preparation

Specific requirements:

  • Practical experience in heterogeneous catalysis
  • Hands-on experience with synthesis/preparation of heterogeneous catalysts
  • Knowledge of catalyst characterization methods
  • Hands-on experience with assessment of the performance of heterogeneous catalysts

What is „Green Chemistry“ in simple words?

It is the way of carrying out chemical processes when thinking about the environment. So, using alternatives to hazardous substances, reducing waste and reducing demand on non-renewable resources and energy is the key point.

The term „Green Chemistry“ was proposed in the 1990s by Paul Anastas and John Warner (Anastas, P. T.; Warner, J. C. Green Chemistry: Theory and Practice, Oxford University Press: New York, 1998, p.30. By permission of Oxford University Press). They defined the Green Chemistry as the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. Moreover, they proposed 12 basic principles of Green Chemistry that cover a broad range of possible improvements in chemical processes that will positively affect the environment.

Currently, over 85% of the industrial chemical processes include at least one catalytic step. That is why catalysis plays a fundamental role in implementing Green Chemistry principles.

In terms of Green Chemistry principles, then catalysts may help a) to increase reaction selectivity, b) to minimize the waste, c) to reduce the energy demands, d) to increase reaction rates. Besides the environmental benefits, the economic benefits will be simultaneously realized in many different applications. So, the future developments in catalysis and catalyst design are the driving force for the Green Chemistry.

Our major scientific focus is the development of the new catalysts that can replace the currently used catalysts that either require more energy to carry out or contain hazardous metals. The vision is to develop the catalysts that are based on available and affordable non-noble metals and are active under mild reaction conditions.

Of course, there is still a lot of challenges on the way to the „green“ industrial process. But challenges are meant to be met and overcome, aren't they?

Topic: Supported Cu-based catalysts for hydrogenolysis 
Funding: Czech Science Foundation - 20-28093S
Date
: 2020-2022 
Goal: The main goal is to shed light on the relationship between synthesis, structure and hydrogenolysis activity of supported Cu catalysts. A partial goal is to maximize Cu dispersion and its stability in the catalysts. 

Abstract: The main goal of the project proposal is to contribute to the understanding of the fundamental issues that lie at the heart of the structure–activity relationship paradigm of the Cu-based hydrogenolysis catalysts. The project will thus focus on controlled synthesis of Cu-based supported catalysts on a variety of well-defined supports to obtain hydrogenolysis catalysts with different structural and physico-chemical properties. In particular, variations in Cu cluster size and improvements in its long-term stability (i.e. sinter-resistance) will be attempted. The activity, selectivity as well as stability of the catalytic activity of the synthesized catalysts will be investigated in hydrogenolysis of esters and the results will be correlated with the catalyst structural and physico-chemical properties to provide information on the structure-activity relationships useful for rational design of hydrogenolysis catalysts. 


Topic: Development of environmentally friendly hydrogenation catalysts
Funding: Ministry of Industry and Trade of the Czech Republic – FV40158
Duration: 2019-2022
Goal: The goal of the project is to develop a new chromium-free catalyst having a comparable stability, activity and durability as the currently used catalyst containing copper and chromium. The new catalyst will be a more environmentally friendly alternative of the current catalyst not only from the application point of view, but also from the catalyst production point of view as the amount of toxic wastes containing chromium (VI) will be reduced.
Project partner: Ranido, s.r.o.


Topic: Investigation and optimization of promoted CuZnAl hydrogenation catalysts 
Funding: Czech Science Foundation - 17-05704S
Date: 2017-2019 
Goal: The goal of the project is to describe the relationship between the composition, structure and properties of promoted CuZnAl catalysts and their catalytic activity and selectivity in hydrogenation and hydrogenolytic reactions.

Abstract: The project investigates promoted CuZnAl hydrogenation catalysts. The hydrogenation catalysts based on CuZn are promising catalysts for hydrogenation of chemical specialties, such as esters. CuZnAl catalysts will be synthesized under controlled conditions relying on co-precipitation, deposition and impregnation methods. The catalysts will be characterized in detail by physico-chemical characterization techniques. This will allow rationalizing the relationship between catalyst synthesis parameters and catalyst structure and its properties. The hydrogenation performance of the synthesized CuZnAl catalysts will be studied by hydrogenation of two model ester compounds (dimethyl adipate and methyl caproate) to the corresponding alcohols. This will facilitate the description of the relationship between the catalyst structure and properties, on the one hand, and catalyst activity and selectivity, on the other hand. The stability of the catalysts will be studied as well.

Topic: Quantifying the basicity of reconstructed layered double hydroxides and correlating this with their performance in base-catalysed reactions
Funding: Czech Science Foundation - 19-22978S
Duration: 2019-2021
Goal: Advanced analysis of the changes in the structural/acid-base properties during the formation of (supported) reconstructed LDHs using in-situ techniques and elucidation of the relationship between the properties of the (supported) reconstructed LDHs and their catalytic performance and stability.
Abstract: The main aim of the project is to provide fundamental understanding of the relationship between the structural/textural/acid-base properties and the catalytic performance (activity/stability) of the reconstructed layered double hydroxides, LDHs, (in both bulk and supported forms). We aim to elucidate which of the basic sites possess superior activity in the aldol condensation of furfural and how to maximize their number. To achieve this ambitious goal, we have set the following specific objectives: (i) To describe the changes of structural/acid-base properties during the transformation of mixed oxides into the reconstructed LDHs using suitable in-situ techniques, (ii) To determine the influence of the support on the structural/acid-base properties of reconstructed LDHs supported on alumina, (iii) To elucidate the relationship between the structural/acid-base properties of the (supported) reconstructed LDHs and their catalytic performance (mainly activity and its long-term stability).

Topic: Investigation of the key factors affecting hydrogenation / deoxygenation of mixtures of oxygenates
Funding: Czech Science Foundation
Duration: 2022 - 2024
Abstract: The project deals with hydrogenation/deoxygenation of model furanic and phenolic compounds in the gas phase over heterogeneous supported metallic catalysts. The focus is on the description of the key parameters that affect hydrogenation/deoxygenation of mixtures of oxygenated compounds and on the elucidation of the origin of differences in the catalytic activity when hydrogenating/deoxygenating individual oxygenates or their mixtures. Apart from the activity and selectivity of catalysts, the influence of catalyst composition and properties (e.g. hydrogenation power and oxophilicity) on activity/selectivity of catalysts and on adsorption/desorption of oxygenates (individual compounds as well as mixtures) on these catalysts will be investigated. The project will contribute to a better understanding of hydrogenation/deoxygenation of mixtures of furanics and phenolics that is important for the future valorization of biomass-derived oxygenates.


Topic: Controlling reaction pathways in hydrogenation of sugar-derived oxygenates by catalyst design – COCAIN
Funding: Czech Science Foundation
Duration: 2021 - 2024
Abstract: Selective transformation of biomass-derived platform chemicals, such as 5-hydroxymethylfurfural and levulinic acid, may afford high-value-added chemicals for future biorefinery schemes and make the chemical industry more sustainable. However, the methods or catalysts reported so far yield poor selectivity towards the interesting/target products. To fully control these transformations, it is essential not only to describe the reaction pathways but to understand the role of specific functionalities of the heterogeneous catalysts on the course of the reactions and to combine intimately appropriate functionalities into advanced multifunctional catalysts to selectively steer the transformation to desired products. The main scientific goal of the project is to understand how the key catalyst-design parameters including the metal nanoparticle size and promotion as well as the support characteristics affect the individual reaction rates and, hence, the selectivity to specific products in 5-hydroxymethylfurfural conversion.

Abstract: The project is focused on understanding of the mutual inhibition effects during deoxygenation of mixtures consisting of different types of oxygenates (fatty acids and phenols). It deals with design and investigation of suitable bifunctional catalysts attempting to describe the relationships between catalyst synthesis parameters and the resulting catalyst properties. The performance of the catalysts will be studied in deoxygenation of mixtures of fatty acid and phenols to understand the influence of one oxygenate type on the other during their deoxygenation. This information will help improving the catalyst design. In addition, the plausible inhibition effect of nitrogen containing compounds will be investigated as well. The obtained knowledge can contribute to progress in deoxygenation of complex feedstocks such as pyrolysis oils from wastewater sludges.
