Title:
POROUS LITHIUM ALUMINATE CATALYST CARRIER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3387318
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a carrier useful as the carrier of a platinum group catalyst or a platinum group metal-base catalyst compsn. as a catalyst used especially at the time of producing carbonic diester.
SOLUTION: This porous lithium aluminate catalyst carrier has 40-1,000&angst average pore diameter, 0.2-1.5ml/g pore volume and a spinel structure and may contain a divalent metal. A platinum group catalytic component is carried on the catalyst carrier to obtain a catalyst. The catalyst carrier is produced using an alumina sol contg. alumina particles and a lithium salt.
