Procedure

A clay/phosphate/cerium nitrate solution was prepared (according to the general teachings of U.S. Patent 5,190,902) by adding 1403 grams of Theile RC-320 kaolin clay slurry to 591 milliliters of water in a high speed mixer. To this mixture, 192 grams of phosphoric acid was then added. To the resulting system, 440 grams of cerium nitrate solution was added. The slurry formulation was then spray dried and the resulting particles calcined at 650° C. for 30 minutes in a muffle furnace. The calcined particles were then mixed with magnesium oxide in a 50/50 weight percent ratio and the resulting material analyzed by a TGA test that showed a SOx absorption rate of 0.21% per minute for the end product material.
