Objective

The objectives of this research programme are the elucidation of the mechanism of gas condensates transformation over mono- and bifunctional ZSM-5 catalysts and the design of the improved catalyst for gas condensates upgrading into gasoline and propane-butane fraction. Training of young scientists will be also an important objective of the project.

The main research activities will include synthesis of ZSM-5 catalysts and their modification with metal oxides; standart and advanced catalyst characterization by XRD, AAS, EDX, SEM, FT-IR, MAS NMR, TG-DTG, TPD NH3, TPD of model hydrocarbons and adsorption measurements; testing of their catalytic activity and investigation of reaction mechanism. The attention will be focused at the mechanistic studies, which will be based on the combination of two experimental approaches: kinetic studies in continious-flow microreactor systems and in situ 13C, 1H and 2D MAS NMR studies of reactant conversions directly on the catalyst surface in the course of the reaction. In different experiments, the conversion of model hydrocarbons and real gas condensate feed will be studied. The specifically labelled compounds with 13C and 2H will be used to follow the fate of individual hydrocarbons during the overall reaction and to determine the role of active sites. The kinetic approach is expected to give information on the overall reaction network and catalyst decay, while in situ approach will give insight in the mechanism of the reaction elementary steps at a molecular level and in the nature of active sites responsible for each step. The combined information gained from these studies will allow to decide on the optimal balance between hydro-dehydrogenation and the acidic functions of the catalyst, required for the best performance of zeolite catalysts in gas condensates conversion and, therefore, to elaborate the guidance for the preparation of improved catalyst. At the end of the project, the improved catalyst for gas condensates conversion into high-octane gasoline will be designed. The production and application of such catalyst will allow overcoming the limitations of the existing technology for gas condensate transformation, namely, low gasoline yields and rapid catalyst deactivation.
