XYLENE ISOMERIZED CATALYST AND ISOMERIZED REACTION PROCESS FOR XYLENE GROUP

摘要

PURPOSE:To manufacture a xylene isomerized catalyst which accelerates with good selectivity only isomerized reaction and deethylation reaction at a low temperature of 400 deg.C or below. CONSTITUTION:A xylene isomerized catalyst is composed of a crystal manganese aluminosilica as a carrier on which platinum is carried, and when isomerized reaction in which the catalyst composed of crystal manganese aluminum silicate as a carrier with platinum carried thereon is performed in the isomerized reaction process of xylene group, the temperature is set in the range of 350-400 deg.C.
