Title:

CATALYST COMPRISING METAL AND HETEROPOLYACID SUPPORTED ON SILICA

Document Type and Number:

Japanese Patent JPH07136519

Kind Code:

A

Abstract:

PURPOSE: To produce a catalyst excellent in n-paraffin isomerization activity at low temperature and not containing a chloride as a support and to catalytically isomerize a paraffin using the catalyst.

CONSTITUTION: A solid acid catalyst composition used comprises (i) a silica support, (ii) a group VIII metal of the Periodic Table and (iii) a heteropolyacid selected from the group consisting of 12-tungstophosphoric acid, 12-tungstosilicic acid, the exchanged aluminum salt of 12-tungstophosphoric acid, the exchanged aluminum salt of 12-tungstosilicic acid and mixtures of those.
