Progress in the APCI support program to assist ERDA in the development of their hot producer gas desulfurization process is reported. An iron oxide-fly ash absorbent will be used in a cyclic fixed-bed operation. Specific objectives are absorbent development, definition of process scale-up criteria, and commercial process design. The physical properties and chemical analyses of prepared sorbents are listed. Dynamic testing is explained and test results for sorbents with different iron oxide sources are presented. The differential equations and derivations for mass and heat transfer are presented. A plan of attack for the solution of these equations is described. The solution to the isothermal sorption equations is presented. Predicted effects of changes in sorption operating conditions and sorbent properties are discussed. The isothermal sorption model agrees with experimental data for H/sub 2/S sorption on iron oxide/fly ash sorbents. The model is used to correlate dynamic data on sorbents using different iron oxide sources. Acceptable sources of iron oxide are identified. The applicability of the work to sorber design is demonstrated. The isothermal model is used to prepare a preliminary design of a sorber with a capacity of 120M SCFH process gas. Sorbent properties obtained from dynamic tests are used in the model. (auth)
