CATALYST AND A METHOD FOR PRODUCTION OF HIGH-OCTANE FUELS AND PROPANE-BUTANE FRACTION USING THIS CATALYST Russian patent published in 2005 - IPC

Abstract RU 2243820 C1

FIELD: petrochemical processes.

SUBSTANCE: high-octane fuels and propane-butane fraction are obtained via conversion of hydrocarbon feedstock on contact with hot catalyst placed in reactor, into which diluting gas is supplied at elevated pressure. Catalyst is Pentasil-type zeolite with general formula xM_2/nO,xAl₂O₃,ySiO₂,zMe_2/mO wherein M represents hydrogen and/or metal cation, Me group II or VII metal, n is M cation valence, m is Me metal valence, x, y, z are numbers of moles of Al₂O₃, SiO₂, and Me_2/mO, respectively, and y/x and y/z ratios lie within a range of 5 to 1000. Metal oxide Me_2/mO is formed during calcination, in presence of oxygen, of Me-containing insoluble compound obtained in zeolite reaction mixture.

EFFECT: increased octane number of gasoline fractions with propane-butane fraction as chief component of gas products, and prolonged inter-regeneration time of catalyst.
