A solid desulfurizer

Abstract

The invention relates to a desulfurizing agent, in particular to a solid desulfurizing agent. The solid desulfurizing agent is prepared from the following components in parts by weight: 3 to 9 parts of calcium oxide, 5 to 16 parts of ferric oxide, 5 to 10 parts of calcium fluoride, 1 to 6 parts of aluminum oxide, 2 to 8 parts of sodium bicarbonate and 7 to 16 parts of a neodymium-containing coordination polymer. The new neodymium-containing coordination polymer is added into the solid desulfurizing agent, so that the obtained desulfurizing agent has the characteristics of good desulfurizing effect and high sulfur content when compared with the existing conventional solid desulfurizing agent in the market.

Description

technical field [0001] The invention relates to a desulfurizing agent, in particular to a solid desulfurizing agent. Background technique [0002] The crude gas produced by gasification or pyrolysis contains dust, HCl and sulfur-containing gas (more than 90% is H 2 S) and other pollutants must be decontaminated before use. When coal gas is used as fuel gas, the sulfur-containing gas will cause corrosion to gas turbine blades and other equipment; as raw material gas, it will poison the catalyst with sulfur, and at the same time, its combustion will be converted into SO 2 Released into the atmosphere will cause acid rain, seriously endangering the environment and human health, so in the process of H 2 The removal of sulfur-containing substances such as S is a necessary link in life and production. The desulfurization rate of the existing desulfurizers is generally low, the desulfurization is incomplete, and the sulfur capacity is low. Contents of the invention [0003] T...
