Abstract
Disclosed in the present invention is an integrated catalyst system for stoichiometric-burn natural gas vehicles, the catalyst system consisting of a three-way catalyst, a molecular sieve catalyst, and a base body, the three-way catalyst and the molecular sieve catalyst being coated on a surface of the base body. In the integrated three-way catalyst and molecular sieve catalyst system of the present invention, at the same time that pollutants such as CO, HC, and NOin the exhaust of stoichiometric-burn natural gas vehicles are processed, the produced byproduct NHcan also be processed, and the conversion rates of CO, HC, NO, and NHare high.
