Results of studies on the conversion of gaseous hydrocarbon feedstock with different compositions into olefin hydrocarbons over zeolite-containing catalysts are presented. The results of catalyst testing indicate that zeolites modified with phosphorus and manganese exhibit high activity in the conversion of lower C2–C4 alkanes into olefin hydrocarbons. It has been determined that the P-containing zeolite catalyst has the highest dehydrogenating activity, and the Mn-containing zeolite catalyst is characterized by a higher overall activity. It is shown that significant conversion of the feedstock is observed within the temperature range of 600–650 С, depending on the hydrocarbon chain length of the initial alkane molecule. For the P-containing zeolite catalyst, almost linear dependence of the yield of olefin hydrocarbons on the conversion of the initial С2–С4-hydrocarbons is observed. At the same time, for the Mn-containing zeolite, the dependence of the yield of olefin hydrocarbons on conversion is determined by the type of initial hydrocarbon feedstock. The acid and textural characteristics of the original zeolite and its modified samples were studied by temperature-programmed desorption of ammonia and low-temperature adsorption of nitrogen, and their distinctive features affecting the properties of the catalysts in the conversion of C2–C4 alkanes into olefin hydrocarbons were established.
