ABSTRACT:
A solid pollution-treatment product consisting of a core material of lime, quicklime or hydrated lime. The core is surrounded by a cracked shell formed of either calcium sulfate or calcium carbonate, such materials being referred to in this and prior applications of inventor by the coined terms "Linfans" and "Linveins", respectively.
The described particulate material is particularly reactive to sulfur oxide bearing gases. Reactivity of such core material is even further enhanced by increasing its porosity through hydration and used in either the hydrated form or a selectively, partially or wholly dehydrated form before exposure to the sulfur oxide pollutants intended to be removed from flue gas or the like.
