Title:
MOLDED ACTIVATED RANEY METAL FIXED BED CATALYST AND ITS PRODUCTION AND USE THEREOF
Document Type and Number:
Japanese Patent JP2001079410
Kind Code:
A
Abstract:

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.

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°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.
