Title:
CATALYST FOR PREPARING LOW-CARBON OLEFIN THROUGH CARBON DIOXIDE HYDROGENATION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/071241
Kind Code:
A1
Abstract:
The present application belongs to the technical field of carbon dioxide recycling, and particularly relates to a catalyst for preparing low-carbon olefin through carbon dioxide hydrogenation and a preparation method therefor. The raw materials of the catalyst comprise ferric salt, magnesium salt, organic amine, and ammonium bicarbonate. The catalyst can adapt to a wider raw material carbon-hydrogen ratio and also has higher catalytic activity and selectivity. The content of iron in the catalyst is relatively high, and organic amine and ammonium bicarbonate are used as raw materials of the catalyst, such that the controllability of the precipitation process is ensured, atomic-scale dispersion of iron and magnesium is ensured, proper active sites are generated, proper interlayer ions and molecules are also inserted, the lamellar spacing is adjusted, and meanwhile, other metal impurity ions cannot be introduced.
