The report gives results of Phase 4 of a study on the CAFB process for gasification/desulfurization of liquid and solid fuels in a bed of hot lime. A new pilot unit was designed and constructed, incorporating such novel features as: a new fluidizing air distributor, high-flow/low-pressure-drop cyclones, and improved refractory construction. Conclusions include: (1) confirmation of the process description by a statistically derived equation; (2) bed age has a significant effect on desulfurization efficiency; (3) heavy residua can be gasified and desulfurized; (4) solid fuels show potential as feedstocks; (5) trace element retention depends on stone replenishment rate (a rate sufficient to maintain bed depth--0.2 molar--is adequate to maintain trace element capture and sulfur removal performance); (6) satisfactory performance of the redesigned pilot unit; (7) a carbon burn-back procedure was not completely effective in cleaning the cyclones; (8) confirmation that coal and Texas lignite are suitable feedstocks for the CAFB and that ash accumulation and fusion do not appear to be limiting; and (9) Texas limestone is satisfactory as bed material if it is available in a suitable particle size range. Remaining work includes performance tests and evaluation.
