Title:

RANEY TYPE CATALYST FOR FIXED BED, ITS PRODUCTION AND USE FOR REACTING WITH ORGANIC COMPOUND

Document Type and Number:

Japanese Patent JP2001054736

Kind Code:

A

Abstract:

To obtain high activity by preliminarily producing metal alloy fibers and/or metal alloy flocks by a crucible metal extraction method, subsequently making them into tablets, pressing them into a mat and/or filling a cartridge with them.

A rapidly cooled material having a controllable shape is obtained by the crucible melting/extracting method, i.e., the method to use a rectangular crucible and a water-cooling copper-made rotary wheel having notches specially formed on the surface of the crucible. The metal alloy flocks or the metal alloy fibers having fixed length and diameter are obtained as the final product according to the design of the notches of the rotary wheel. Subsequently the cartridge is filled with these flocks and/or fibers and they are activated with caustic soda solution. Or these flocks and/or fibers are made into tablets and/or pressed into a mat, optionally using a binder such as nickel powder, which are then calcinated in the air and activated with caustic soda solution.
