Abstract
The present application relates to catalyst preparation technology, aims to provide a kind of Co-SSZ-39 catalyst for selective catalytic reduction of methane denitration and preparation method.The catalyst is with the SSZ-39 molecular sieve with AEI topology as carrier, by ion exchange method, cobalt element is supported on the molecular sieve, and the mass percentage of cobalt element in the catalyst is 1.26-5.16%;The cobalt element includes Co 2+ And Co 3+ , and Co 2+ Content is 61%-85%.The catalytic performance of the catalyst is better than most of the currently reported catalysts, and performs well in water resistance, carbon monoxide resistance and sulfur dioxide resistance and hydrothermal stability.The present application first uses the molecular sieve with AEI topology as carrier for CH4-SCR catalyst, which provides a new idea for the research of catalyst.
