PURPOSE:To provide a catalyst with short fiber carriers for treatment of gases which contacts with gaseous flow stably and applies no pressure drops upon the same by coating catalyst components on a fabric or net-like object made of glass fibers stuck with heat resistant materials. CONSTITUTION:Short fibers of <=3mu diameters consisting essentially of alumina, silica, titania, magnesia or calcium oxide are adhered to long glass fibers or metallic wires by using heat resistant adhesive agents or the like. Known catalyst components are stuck by a suitable method on the surfaces of a fabric or net-like object made by weaving said long glass fibers or metallic wires and is subjected to the activation treatment. The resultant catalyst with the short fiber carriers contributes to the prevention of the channelling of gaseous flow and the reduction of pressure drop. The catalyst is used for removal of CO and hydrocarbons in gases. |
