This is the fourth monthly progress report of the APCI support program to assist ERDA in the development of their hot producer gas desulfurization process. An iron oxide-fly ash absorbent will be used in a fixed-bed cyclic operation. Specific objectives of APCI are absorbent development, definition of process scale-up criteria, and commercial process design. Experimental absorbents have been prepared using different sources of iron oxide, iron oxide contents, and pellet sizes. The repaired ERDA pressure reactor has been installed. Unit start-up is expected in November 1975. Differential equations have been derived to describe the dynamics of the adsorption and regeneration processes. A step-by-step plan of attack has been developed to solve this system of non-linear partial differential equations.
