Title:
CATALYST CARRIER
Document Type and Number:
WIPO Patent Application WO/2007/069500
Kind Code:
A1
Abstract:
Disclosed is a catalyst carrier which is used for carrying a catalyst thereon. The
catalyst carrier is characterized in that the apparent specific heat measured at
800˚C is 1.8 times or more greater than that measured at room temperature, wherein
the apparent specific heat means a charge heat capacity required for substantially
increasing the temperature of a unit mass (Kg) by 1 K in contemplation of the influence
of endotherm or exotherm caused by change in crystalline form, partial melting,
coagulation, phase transformation, vitrification, amorphous-formation, crystallization
and the like. Also disclosed is a catalyst converter having a catalyst carried
on the catalyst carrier. Further disclosed is an exhaust gas processing system
using the catalyst converter.
