Abstract The Phase II addendum report describes the laboratory work performed to screen selected organic solids for ability to remove sulfur dioxide from synthetic flue gas, and obtain more detailed data on the most promising organic solid (s). A principle accomplishment of the task was the identification of a number of waste materials which have high potential for removal of sulfur dioxide from flue gases. Organic materials were selected on the basis of: Known or postulated ability to take up sulfur dioxide; Price and availability; Thermal stability; Regenerability; and Mechanical properties. Five organic materials were selected which offer promise for removing sulfur dioxide from flue gases: Cellulosics; Nigrosin; Poly(N-vinylcarbazole); Pyrolyzed poly(vinylchloride); and Pyrolyzed poly(acrylonitrile). The specific cellulosics selected were: waste newsprint, sawdust and cotton. All seven candidates (this includes the three cellulosics) were found to be thermally stable in flue gas, while all but nigrosin were found to take up substantial amounts of sulfur dioxide from synthetic flue gas streams. Of the solids which were evaluated, newprint was found to be the most promising. More detailed accumulation of data was performed on newsprint utilizing synthetic flue gases at temperatures encountered in flue gas streams (215 - 300F). Newsprint picks up approximately 1-2% by weight sulfur dioxide in 20 minutes at a flow rate of ca., 200 vol/hr. Newsprint has a capacity of approximately 10% SO2 by weight. Desorption streams of 16-26% by volume sulfur dioxide are obtained from newsprint at desorption temperatures of 350-450F. (Author)
