    Abstract: PROBLEM TO BE SOLVED: 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. SOLUTION: 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.

    Abstract: PROBLEM TO BE SOLVED: To produce an activated fundamental metal fixed bed catalyst for hydrogenating saturated and unsaturated esters under a condition milder than existing technique with better activity and selectivity. SOLUTION: A mixture consisting of a catalyst metal, which consists of at least one kind of a Raney process metal being a catalytically active metal, an alloy component possible to be eluted and, if necessary, a cocatalyst, at least one kind of a binder comprising at least one king of a pure Raney process alloy and a wetting agent is homogenized and molded to obtain a catalyst precursor, which is, in turn, baked at a temp. lower that 850 deg.C and the alloy component possible to be eluted is eluted by using alkali until the thickness of an activated outer layer becomes 0.05-1 mm to activate the sintered catalyst precursor and this catalyst precursor is succeedingly washed and the obtained catalyst is introduced into a perrhenic acid soln. or a soln. of other rhenium salt over a sufficient time to be activated and the activated catalyst is doped with rhenium as a cocatalyst to produce a molded artivated Raney metal fixed bed catalyst.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing isophoronediamine from isophoronenitrile, comprising hydrogenating in the presence of a Raney catalyst having a small apparent density and a good hydrogenation activity. SOLUTION: This method for producing the isophoronediamine from isophoronenitrile, isophoronenitrileimine and/or their mixture comprises hydrogenating into the isophoronediamine in the presence of at least ammonia, hydrogen, and a hollow type Raney hydrogenation catalyst based on at least cobalt, nickel, copper and/or iron. The production of the isophoronediamine in a high conversion and in an extremely good yield can be achieved using substantially small amounts of the catalyst materials, because the apparent density of the catalyst is small.
