Title:
EGGSHELL-TYPE CATALYST, PREPARATION METHOD THEREFOR, AND USE THEREOF IN PROPYLENE HYDROFORMYLATION REACTION
Document Type and Number:
WIPO Patent Application WO/2023/207584
Kind Code:
A1
Abstract:
Disclosed in the present invention are an eggshell-type catalyst, and a preparation method therefor, and the use thereof in a propylene hydroformylation reaction. In the eggshell-type catalyst, phosphine ligand resin pellets with developed pore structures are used as a carrier, and one, two or more of metals Rh, Co, Ir, Ru and Pd are used as active components. The spatial distribution of the metal active components in the resin pellets is effectively regulated by finely regulating the pore structure of the resin carrier pellets and adding a method of competitive adsorption coordination, such that the prepared eggshell-type catalyst has the characteristics of relatively high activity in the propylene hydroformylation reaction and good n-butyraldehyde selectivity in the product aldehyde.
