Moore, W E

This patent describes a method for reducing the sulfur content of exhaust gases from the combustion of hydrocarbons. It comprises rapidly heating an alkali- or alkaline-earth-based sorbent powder to a temperature near its vaporization point so that the sorbent becomes an activated sorbent comprising part vapor and part liquid; injecting the activated sorbent into a sulfur-containing gas stream so as to form sulfur-containing sorbent; and quenching and collecting the sulfur-containing sorbent.
