Patrick John McGauley: Process for the production of sorbent solids for use in the desulfurization of gases. Mandeville and Schweitzer, December 6, 1977: US04061716 (20 worldwide citation)

This disclosure describes a process for the preparation of iron-bearing and calcium-bearing sorbent solids for use in the desulfurization of gases. The process involves mechanical procedures for generating porous agglomerated solids that are high in surface area and uniquely suitable in both particl ...

Patrick John McGauley: Preparation of iron oxide sorbent for sulfur oxides. Donnelly Maky Renner & Otto, February 15, 1977: US04008169 (14 worldwide citation)

A highly sorbent iron oxide for use in the purification of dilute sulfur and oxygen-bearing gases is prepared by a two step process which involves a low temperature decomposition of iron sulfate and a low temperature oxidation of the intermediate product.
