An
efficient catalyst for catalytic
incineration of VOC
waste gas and a preparing method thereof are disclosed. The method includes (1) fully stirring active
metal salt solutions according to a certain ratio to obtain a mixture solution, then adding a proper amount of
activated carbon, stirring the mixture for 2-6 h, then adding
activated alumina and
cerium dioxide
powder as a catalyst carrier, stirring the mixture overnight, and finally stirring and
drying the mixture at a constant temperature to obtain mixture
powder, with the active metals being two or more selected from
copper,
manganese,
cobalt,
antimony and
lanthanum; (2) mixing the dried mixture
powder and a pore forming agent, adding the mixture into a
ball mill, performing ball milling for 4-8 h, then adding a binder, fully mixingthe materials, and performing
extrusion molding to obtain a catalyst precursor; and (3)
roasting the catalyst precursor at 350-750 DEG C for 2-6 h. The method is simple in process and low in
energy consumption, and the obtained catalyst is low in cost, high in poisoning resistance, wide in applicability, free of secondary
pollution, long in service lifetime and high in
catalysis efficiency.
