Title:
FISCHER-TROPSCH SYNTHESIS CATALYST, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/060707
Kind Code:
A1
Abstract:
A Fischer-Tropsch synthesis catalyst, a preparation method therefor, and an application thereof, relating to the field of Fischer-Tropsch synthesis catalysts. The catalyst comprises: 10-45 wt% of Co, 0.01-2.5 wt% of Mn, 0.01-1.5 wt% of Cl, 0.5-8 wt% of ZrO2, and 35-85 wt% of bulk TiO2; the molar ratio of Cl to Zr is 1: 20-1: 0.1; and the grain size of cobaltosic oxide in the catalyst is 16-27 nm. The TiO2 is composed of two crystal forms, namely anatase and rutile; and the content of the crystal form, namely the anatase is greater than the content of the crystal form, namely the rutile. The prepared catalyst is low in methane selectivity, high in activity, good in sintering resistance and hydrothermal resistance and excellent in stability.
