Title:
GRAPHENE MODIFIED IRON-BASED CATALYST AND PREPARATION AND APPLICATION THEREOF FOR USE IN FISCHER-TROPSCH REACTION
Document Type and Number:
WIPO Patent Application WO/2018/201742
Kind Code:
A1
Abstract:
A graphene modified iron-based catalyst and an application thereof for use in a Fischer-Tropsch reaction to prepare olefins. The catalyst is composed of 0.01-30% of graphene in percentage by mass, 0-20% of an auxiliary agent, and 60-99.99% of an iron oxide. A preparation process of the catalyst successively places graphene, an iron oxide powder, and the auxiliary agent into an aqueous solution for ultrasonication and stirring, and then conducting rotary evaporation, drying, and baking. The catalyst exhibits excellent activity in the Fischer-Tropsch reaction, maintains a high CO conversion rate of more than 90% at a high reaction space velocity for a long period of time. Moreover, the resulting product has a low alkane content and an olefin-alkane ratio of up to 14, and has high industrial application value.
