FIELD: chemistry.
SUBSTANCE: invention refers to oil refining and petrochemical industry, specifically to methods of effective low-polymeric hydrocarbon pyrolysis catalysts. Described is low-polymeric paraffin fraction pyrolysis catalyst containing pentacyl family zeolite with silica ratio SiO2/Al2O3=20-80, modifiers chromium and fluorine, and binding agent aluminium oxide specific for the fact that simultaneously chromium and fluorine modified pentacyl family zeolite is used as catalyst base in ratio as follows, wt %: zeolite 55 - 80; chrome oxide 1 - 6.75; hydrogen fluoride 1 - 5.8; binding agent (γ-Al2O3) - the rest.
EFFECT: lowered number of technological operations for production of effective pentacyl containing catalyst for pyrolysis of low-polymeric hydrocarbons, reducted hard-to-dispose catalyst sewage, higher running time of regeneration-free pentacyl containing the catalyst.
