OXIDE OF TITANIUM/SILICON/TUNGSTEN, DENITRATION CATALYST OBTAINED BY USING THE OXIDE, METHOD FOR PREPARING THE OXIDE, AND DENITRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oxide capable of being used in a catalyst which can efficiently treat nitrogen oxides in exhaust gas and particularly, can effectively treat the exhaust gas to be generated from a gas-fired boiler or a gas turbine.;SOLUTION: The oxide of titanium/silicon/tungsten has two peaks at the A peak of 1-20 μm and the B peak of 0.006-0.06 μm and at least one of the A peak and the B peak is the highest when the pore size of the oxide is measured within a range of 0.003-40 μm. A catalyst obtained by using the oxide, a method for producing the oxide, and a denitration method using the catalyst are also provided.;COPYRIGHT: (C)2014,JPO&INPIT
