METHOD FOR PRODUCING CATALYST FOR PRODUCING UNSATURATED HYDROCARBON AND METHOD FOR PRODUCING UNSATURATED HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To control degradation of a catalyst used for catalytic decomposition of naphtha and to achieve long lifetime of the catalyst.;SOLUTION: The catalyst according to the embodiment contains aluminosilicate. By bringing the aluminosilicate into contact with an acid solution and a silicate solution, the outer surface of the catalyst is inactivated, the carbon accumulation on the catalyst is controlled, and thus the degradation of the catalyst is controlled.;COPYRIGHT: (C)2013,JPO&INPIT
