▎ 摘  要

NOVELTY - Modified catalyst carrier comprises least one of molecular sieve and/or inorganic oxide as a carrier, and carbon material and metal oxide dispersed on carrier. USE - Used as modified catalyst carrier. ADVANTAGE - The catalyst carrier: improves the dispersion of active components in the catalyst; makes the active components reach a proper dispersion state and keeps relatively stable; prevents the growth of metal crystal grains of the active component, prolongs the service life of the catalyst, increases the specific surface area of the catalyst and improves the denitration effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified catalyst carrier comprising dispersing molecular sieve and/or inorganic oxide in water to obtain dispersion A, dispersing the carbon material precursor in water to obtain dispersion B, dispersing the dispersion A and dispersion B into the metal salt solution to obtain dispersion C, stirring the dispersion C, drying, and calcining the sample to obtain final product.
