Doctoral Programme,
Faculty of Environmental Technology
The aim of the doctoral study programme Energy and Fuels is to educate qualified professionals who will be able to use in practice the latest scientific knowledge concerning chemical and energy processing and utilization of solid, liquid and gaseous fuels and biofuels, as well as chemical technologies used in power engineering. Students get a broad chemical-engineering background extended with detailed knowledge of specific technologies as well as other skills how to independently plan and manage research activities, to orientate themselves in modern information technologies, to effectively use electronic information resources, to comprehensively process and evaluate experimental data and to prepare quality scientific publications and presentations. CareersGraduates of the programme generally find job in the management of fuel manufacturers and distributors, in the energy sector or in state administration, as well as researchers in the field of applied research. Graduates of the specialization Petroleum and Alternative Fuels Technology have a comprehensive knowledge of technologies for processing crude oil into fuels, heating oils, bitumen, lubricants and petrochemicals. They are also experts in the use of alternative raw materials for the production of fuels and chemicals and know also to solve environmental problems associated with the processing of oil and the use of products of its processing. Graduates of the specialization Chemical Technology in Energetics are experts in chemistry and technology of conventional fossil, nuclear and renewable energy systems. They have skills to optimize chemical modes of energy cycles, to design and operate technologies for the treatment of feed, process and wastewater in the power industry and they are corrosion specialists in the power industry. They are also qualified to solve the environmental impacts of energy production. Graduates of the specialization Gaseous and Solid Fuels are experts to design technologies for upgrading solid fuels and biofuels by thermal processes as well as technologies for purification of energy gases, biogas, exhaust and waste gases. They have skills to analyse and remove harmful substances from air polluting exhaust and waste gases and to monitor compliance with related legislation. They are specialists in the management of activities concerning mining, treatment, transportation, storage and distribution of natural gas. Programme Details
Vypsané disertační práce pro rok 2025/26Innovative hydrogenation catalysts for the valorization of compounds present in bio-oils
AnnotationBiooils are in important source of compounds that can be key intermediates in chemical utilization of lignocellulosic biomass. Their conversion affords most importantly valuable monomers as well as component of aviation fuels. The dissertation will focus on the development of heterogeneous catalysts that will facilitate the conversion of phenolic and/or furanic compounds into desired valuable products in accordance with green chemistry principles.

Novel hydrogenolysis catalysts for the valorization of biomass-derived oxygenates
AnnotationHydrogenolysis is an important reaction for selective valorization of renewable feedstocks. Besides hydrogenolysis of ester to alcohols that is already a mature industrial process, which, however, needs new more environmentally-friendly catalysts, the attention has been also recently directed at hydrogenolysis of ethers as a key reaction for efficient valorization of lignin. The aim of the dissertation is to identify and describe the fundamental parameters of hydrogenolysis catalysts. The ambition it to reveal both common as well as specific requirements on the composition and properties of catalysts for hydrogenolysis of esters and ethers. The dissertation will focus on the synthesis and characterization of catalysts that will be studied in hydrogenolysis of model esters and ethers to determine their activity, selectivity and stability.

Maximizing motor gasoline production at the molecular level
AnnotationThe PhD thesis will be focused on maximizing the yield of naphtha hydrocarbons in the existing refinery technology scheme. It will assess the distribution of all naphtha hydrocarbons to the existing refinery technologies, i.e., naphtha hydrotreater, naphtha isomerization, and catalytic reforming. The effect of the composition of the processed crude oils on this distribution will be investigated. It will analyze bottlenecks in the current refinery technological scheme for the processing of naphtha fractions and propose a feasible way for removing them. With the aid of modern analytical methods and knowledge concerning naphtha fractions analysis and with the aid of modern simulation methods, it will propose optimization of current naphtha distribution scheme based on the application of a break-through concept of “placing each naphtha molecule in the right place”. Using this concept, it will suggest the possible addition of new naphtha processing technologies to the current refinery scheme allowing both the optimization and the maximizing motor gasoline production in the refinery.

Preparation of new types CuZnAl hydrogenation-dehydrogenation catalysts
AnnotationHydrogenation-dehydrogenation reactions are essential for the chemical valorization lignocellulosic biomass. The aim of the dissertation will be the design and study of new types of CuZnAl catalysts with a controlled distribution of copper for efficient hydrogenation of furfural to furfuryl alcohol and of cyclohexanone to cyclohexanol and for dehydrogenation of these alcohols to the respective aldehydes and ketones. Thanks to studying both hydrogenation and dehydrogenation it will be possible to reveal the effect of catalyst structures on their on their activity. Therefore, the dissertation will focus on the synthesis of hydrogenation and dehydrogenation catalysts to maximize their activity, characterization of active catalyst centers, testing of activity, selectivity and stability of the developed catalysts, and finding and understanding the relationships between synthesis and activity parameters of developed catalysts in the aforementioned reactions.
