CATALYST FOR PRODUCING UNSATURATED HYDROCARBON, METHOD FOR MANUFACTURING THE CATALYST AND METHOD FOR PRODUCING UNSATURATED HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To attain longer life of a catalyst used for catalytically cracking a hydrocarbon such as naphtha by suppressing deterioration of the catalyst.;SOLUTION: One embodiment of a catalyst for producing an unsaturated hydrocarbon comprises: a crystalline aluminosilicate; and silica particles which are coated with the crystalline aluminosilicate and have a particle diameter of 5 to 300 nm. The catalyst for producing an unsaturated hydrocarbon is obtained by bringing a crystalline aluminosilicate into contact with a colloidal silica.;COPYRIGHT: (C)2014,JPO&INPIT
