Abstract
A supported catalyst and preparation method thereof, the catalyst comprising an organic polymer material carrier and Raney alloy particles supported on the organic polymer material carrier, wherein substantially all of the Raney alloy particles are partially embedded in the organic polymer material carrier. The catalyst can be used in hydrogenation, dehydrogenation, amination, dehalogenation or desulfuration reactions.
Claims6
A process for preparing a particulate supported catalyst,
- comprising the steps of:
- (1) providing thermoplastic organic polymer material particles;
- (2) placing the organic polymer material particles in Raney alloy particles so as to make the organic polymer material particles completely surrounded by the Raney alloy particles;
- (3) pressing in a platen press the mixture of the Raney alloy particles and the thermoplastic organic polymer material particles at the mould processing temperature ranging from 200° C.-250° C. and a pressure between 7 MPa and 20 MPa of the thermoplastic organic polymer material so as to push a portion of the Raney alloy particles at least partially into the thermoplastic organic polymer material support particles, so that the resulting supported catalyst comprises 2 wt. % to 95 wt. % of the Raney alloy and 5 wt. % to 98 wt. % of the organic polymer material support, based on the total weight of the supported catalyst;
- and
- (4) cooling, then sieving, to obtain the particulate supported catalyst.
