DEHYDROGENATION OF С 1 –С 5 PARAFFINS ON Cr 2 O 3 /Al 2 O 3CATALYSTS IN FLUIDIZED AND FIXED BED REACTORSPakhomov N.A., Kashkin V.N., Molchanov V.V., Noskov A.S.PP-III-28Boreskov Institute of Catalysis, Prosp. Akad. Lavrentieva, 5, Novosibirsk 630090, Russia,e-mail: pakhomov@catalysis.ruQualified processing of С 3 –С 5 paraffins, entering into gas condensate, associatedpetroleum gas (APG) or natural gas liquids (NGL), is a very important problem of the oil-andgasindustry of Russia. One way to process the above substances is catalytic dehydrogenationresulting in the production of olefin and diolefin hydrocarbons. In the present report weconsider both theoretical and experimental feasibility of dehydrogenation of C 1 –C 5 mixtureswithout preliminary separation of individual components.The work includes thermodynamic calculations of the equilibrium conversion degreesupon dehydrogenation of model C 1 –C 5 paraffin mixtures and NGL.It is common knowledge that dehydrogenation conversion degree is determined by athermodynamic equilibrium. At the similar temperature and pressure values, the equilibriumdehydrogenation degree (reactivity) increases in the paraffin series with an increase in thenumber of carbon atoms and the degree of paraffin branching [1]:С 2
