FIELD: petrochemical processes and catalysts.
SUBSTANCE: invention provides rhenium oxide catalyst on anion-containing gamma-alumina-based support: 0.1-10.0% Re2O3 and 0.2-4.0% fluorine based on the weight of alumina. Catalyst is prepared by impregnating alumina, including 0.2-4.0 wt % fluorine, with rhenium compound solution, drying resulting mass, and subjecting it to heat treatment in oxidative and/or inert medium at 600-900°C. Propylene synthesis process including metathesis of C2-C4-olefinic hydrocarbon blend or ethylene alone is also described.
EFFECT: increased catalytic activity and simplified technology.
