This is a report on Task I, Absorbent Development, entitled ''Hot Stage Desulfurization of Gasified Coal.'' Thirty-nine absorbent preparations were made, and from these 182 samples were prepared. Such properties as bulk density, crushing strength, porosity, surface area, and pore-size distribution on many of these samples were measured. Composition in terms of iron oxide sources and compositions were varied and binders and other components were also varied. Absorbent was produced in two different diameters in order to test that effect on activity. It was found possible to prepare absorbents over a wide range of iron oxide contents and to maintain some porosity (as defined by water absorption) at the highest added iron oxide levels and to produce reasonably hard (crush resistant) absorbents at the lowest levels. Silica and bentonite were interchangeable in use and in fact could be omitted (in one preparation only) with the production of hard extrudate with acceptable porosity.
