Title:

GALLOALUMINOSILICATE CATALYST, METHOD OF PREPARING SAME GALLOALUMINOSILICATE CATALYST, AND METHOD OF PREPARING BTX USING SAME GALLOALUMINOSILICATE CATALYST

Document Type and Number:

WIPO Patent Application WO/2021/040314

Kind Code:

A1

Abstract:

Provided are a galloaluminosilicate catalyst, a method of preparing the galloaluminosilicate catalyst, and a method of preparing BTX using the galloaluminosilicate catalyst. The method of preparing the galloaluminosilicate catalyst comprises: a step of forming a precursor solution comprising a silicone precursor, an aluminum precursor, a gallium precursor, and a carbon template material; and a step of crystallizing the precursor solution to form a galloaluminosilicate catalyst. The galloaluminosilicate catalyst is prepared by the method and has gallium atoms positioned within crystals of the galloaluminosilicate catalyst. The method of preparing BTX comprises: a step of filling a reactor with the galloaluminosilicate catalyst; a step of raising a temperature of the reactor to a reaction temperature; and a step of providing propane to the reactor to conduct a dehydroaromatization reaction.
