Lignosulfonate-modified calcium hydroxide for SO2 control during furnace injection.

摘要

A method is provided for removing sulphur-containing gases from fossil fuel-fired combustors comprising the step of introducing sorbent particles consisting of calciumhydroxide or calcium-magnesiumhydroxide modified with a ionic surfactant like calcium lignosulfonate into the exhaust gases. It is also discribed the method of preparing those particles
