Title: Molten salt type catalyst
Inventor: KAYAMA TOMOYUKI
IPC: F01N3/24
Filed: 2001-01-17
Abstract: PROBLEM TO BE SOLVED: To obtain a practical molten salt type catalyst which can burn/remove PM even in a low temperature area and can be arranged stably in a car exhaust system. SOLUTION: The catalyst is composed of a solid carrier and a catalyst component containing at least one selected from silver nitrate, an alkali metal nitrate, an alkaline earth metal nitrate, and a rare earth metal nitrate, which are supported on the solid carrier.
