Number: 5,126,300
Year: 1992
Patent Status: Issued
Authors: Pinnavaia, T.J., C.A. Polansky, J. Amarasekera

A method for preparing smectite clay alkaline earth metal hydroxide and carbonate composite materials is described. The method uses low amounts of the clay added to water to which is added calcium oxide or calcium hydroxide. Optionally the calcium carbonate is formed in situ by exposure to air or to carbon dioxide in the solution. The product is dried to form the composite material which is used to remove SO.sub.x from flue gases.
