METHOD OF SYNTHESIS OF OLEFIN C<SB>3</SB>-C<SB>5</SB>-HYDROCARBONS

摘要

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention describes a method of synthesis of olefin C3-C5-hydrocarbons by dehydrogenation of the corresponding paraffin hydrocarbons. Method is carried out in the system reactor-regenerator with boiling layer of aluminochrome catalyst that is a mixture where content of catalyst (an abrasion index is 20-30 wt. -%) is 3-40 wt.-% and the rest - catalyst that has an abrasion index 1-10 wt. -%. EFFECT: decreased catalyst consumption, improved heat-mass exchange indices of boiling layer, decreased erosion of an equipment. 2 tbl, 4 ex
