Abstract
PURPOSE:To obtain a denitrification catalyst having high capacity at high temperature range as a catalyst for catalytic reduction by supporting a catalyst component on a carrier of which the heat resistance porous surface is covered by titania and the like. CONSTITUTION:As a catalyst used in denitrification of nitrogen oxides in exhaust gas by catalytic reduction, a heat resistant porous substrate such as alumina, cordierite and the like is immersed in an aqueous solution of titania alcoholate, zirconium nitrate and the like to coat titania and zirconia. Thereafter a catalyst componenet such as oxide of cerium, tungsten, iron and the like is independently or in combined form supported on said substrate. The obrained catalyst removes nitrogen oxides in exhaust gas effectively and economically in a high temperature atmosphere of 400 deg.C or higher.
