Abstract
Fixed-bed Raney-type catalysts are made from metal alloy fibers and/or flakes previously fabricated according to the crucible metal extraction method and then tablated, pressed in mats and/or located into a cartridge. The catalysts are used for the hydrogenation, dehydrogenation, isomerization, reductive alkylation, reductive amination, and/or hydration of organic compounds.
Claims21
A fixed-bed Raney-type catalyst comprising:
- at least one metal alloy fiber or flake formed by crucible metal extraction.
A method of producing fixed-bed Raney-type catalysts comprising forming metal alloy fibers or flakes from a melt of a catalytic metal and an extractable alloying component as a molten material in a crucible, rapidly cooling the molten material under controlled conditions so as to form the desired fiber or flake.
