RANEY METALLIC CATALYST OF FIXED BED, ITS PRODUCTION AND POLYMER HYDROGENATING METHOD USING THE CATALYST

Title:

RANEY METALLIC CATALYST OF FIXED BED, ITS PRODUCTION AND POLYMER HYDROGENATING METHOD USING THE CATALYST

Document Type and Number:

Japanese Patent JPH10151350

Kind Code:

A

Abstract:

To provide the Raney metallic catalyst of a fixed bed having macropores, sufficient mechanical stability and high catalytic activity and released from the defects of the conventional technique such as the low macropore ratio or the presence of a considerable amt. of α-alumina and to produce the corresponding hydrogenated polymer with a high conversion rate in high yield.

The activated Raney metallic catalyst of a fixed bed formed not from a metal powder but from the alloy of aluminum and at least one kind of subgroup VIII metal contains ≥80vol.% macropores, based on the total volume of the pores. This catalyst is used to hydrogenate a low-molecular-weight and highly polymerized org. compd.
