Abstract

PURPOSE: To improve mercury removing efficiency, eliminate clogging and make possible long-term use by using the one consisting in carrying metal sulfide on the carrier of honeycomb structure as a removing agent for mercury in gas.
CONSTITUTION: An absorbent 4 is formed as a honeycomb structural body provided with a multiplicity of holes 6 of, for example, a square in section by leaving an equal spacing l'. The shape thereof is determined by the characteristic, flow rate, velocity, etc. of the gas to be treated. For the carrier of the absorbent, inorg. materials such as, for example, activated alumina, titanium oxide or others are used, and if the gas is of low temp. and is less corrosive, plastics are used as well. Such carrier is impregnated with soluble salts, after which it is passed through a hydrogen sulfide gas or an aqueous sodium sulfide soln., whereby metals are converted to sulfide. The absorbent manufactured in this way is difficult to cause peeling of the carrier and is free from clogging trouble even when used in treating gases contg. much soot and dust.
