Desulfurization catalyst

Abstract

The invention provides a desulfurization catalyst, which is composed of the following ingredients (by weight): 12-18 parts of aluminium oxide, 5-10 parts of zinc oxide, 4-8 parts of nickel oxide, 3-6parts of titanium dioxide, 10-20 parts of magnesium oxide, 1-10 parts of zirconia, 0.1-10 parts of MCM-22 molecular sieve, 1-15 parts of rare earth oxide, 5-30 parts of active metal, 8-12 parts of a binder, and 24-28 parts of an auxiliary agent. By the addition of aluminium oxide, zinc oxide, nickel oxide, titanium dioxide, magnesium oxide, rare earth oxide and active metal, activity of the product can be enhanced, the catalytic effect is good, and catalytic efficiency is high. With the addition of the binder, the product can be made into various shapes such as granular shape, columnar shape,cellular shape, Raschig ring shape and the like. The product can be selected for a fluidized bed and a fixed-bed reactor, has a wide application range, and is suitable for industrial promotion.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a desulfurization catalyst. Background technique [0002] With the continuous deepening of the industrialization process of countries all over the world, SO 2 Pollution has surpassed smoke pollution to become the largest pollutant in the air environment. Flue gas desulfurization (FGD) is different from other desulfurization methods and is the only desulfurization method for large-scale commercial application in the world. It is the control of acid rain and SO 2 The most effective technical means of pollution. [0003] At present, there are many kinds of desulfurization catalysts on the market, but they generally have the defect of poor desulfurization effect. Researching a desulfurization catalyst with good desulfurization effect has become one of the current important topics. Contents of the invention [0004] The present invention aims at the above technical proble...
