Oxidation Catalyst for Exhaust Gas Purification, Catalyst Structure for Exhaust Gas Purification and Method for Purifying Exhaust Gas
摘要:
An oxidation catalyst for exhaust gas purification, comprising a carrier containing titania and zeolite, and a noble metal supported on the carrier, wherein the quantity of the zeolite is within a range from 35 to 50% by weight relative to the catalyst. This oxidation catalyst for exhaust gas purification exhibits favorable SOF removal performance, particularly superior CO and HC removal performance, and favorable resistance to sulfur poisoning, and is consequently ideal for the purification of an exhaust gas emitted from an internal combustion engine such as a diesel engine that uses a fuel containing sulfur.
