Abstract
The invention provides a catalyst carrier with high reaction efficiency. The catalyst carrier comprises a shell, a carrier body and baffles, wherein the carrier body in the shell is honeycomb-shaped; the section of each cell of the carrier is in a regular hexagon shape; four baffles are arranged on each side face in each cell to form three induced air ducts; catalyst layers are arranged on two side faces of the baffles; the width of each induced air duct is 4-6mm; the thickness of each catalyst layer is 0.5-1mm; the catalyst layers are molding layers which are prepared from pyrolytic oxides and have catalytic activity. The multiple baffles are arranged in the cells of the carrier to form multiple induced air ducts, metal catalysts are arranged on inner walls of the induced air ducts, and waste gas passes through the induced air ducts and fully reacts with the inner walls of the induced air ducts, so that the reaction efficiency can be greatly improved and the reaction rate of the metal catalysts is improved.
