SULFATED ZINC FERRITE CATALYST, PREPARATION METHOD THEROF AND PRODUCTION METHOD OF 1,3-BUTADIENE USING SAID CATALYST

摘要

PURPOSE: Sulfated zinc ferrite catalyst, method for preparing the same, a method for preparing 1,3-butadiene using the catalyst are provided to improve the yield of an 1,3-butadiene preparing process regardless of the content of a C4 mixture including normal butane and normal butene. CONSTITUTION: Single phase zinc ferrite is impregnated into a sulfate aqueous solution which is represented by chemical formula, M_2SO_4 or M_2S_2O8. M is H or NH_4. The surface of the zinc ferrite is sulfated. A filtering process and a drying process are followed. Sulfated zinc ferrite catalyst is obtained. A C4 mixture is prepared as the reactant of an 1,3-butadiene preparing process under the sulfated zinc ferrite catalyst. Air and steam are applied to the C4 mixture and the sulfated zinc ferrite catalyst. The C4 mixture includes normal-butane and normal-butene.
