Abstract

A conversion of light hydrocarbons (C2–C5) over HZSM-zeolite-containing catalysts modified by the VA Group metals was studied. The process was carried out in a flow reactor at varying temperature from 350 to 400 °C, pressure – 0.1-0.5 MPa and space velocity – 100-300 hr-1. It was observed that catalysts had high activity in the process of interaction between pentane and ethylene at temperature 350-400 °C and P = 0.1 MPa. The conversion of pentane and ethylene at these conditions over the catalyst P-3 are > 98% and 99-100% respectively. The reaction products are C1–C4 alkanes, C3–C4 alkenes and C5+ hydrocarbons of normal and iso-structure, benzene, ethyl-benzene, xylene, toluene. Maximum yield of C5–C7 alkanes is 91.6% over P-2 and ethyl-benzene is 36.6% over P-3 catalyst observed at mild conditions T = 350 °C and P = 0.1 MPa. Yield of benzene is 1.3-1.4% that meets to environmental requirements. The composition of alkylation gasoline depends on the catalyst nature. Studied zeolite-containing catalysts are polyfunctional and carry out the reactions of dehydrogenation, isomerization, cyclization, alkylation and partly cracking of hydrocarbons by one step. The process scheme is presented.
