Mild temperature gasification [electronic resource] : Partitioning sulfur to gas as H₂S. Technical report, December 1, 1992--February 28, 1993.
Bench-scale, mild-temperature fluidized bed gasification (MTFBG) of three high sulfur Illinois basin coals (IBC) mixed with phosphoric acid will be performed to initiate development of an advanced processing technology which partitions coal sulfur to the gas phase as H₂S. The influence of coal type,...

| 520 | 3 | |a Bench-scale, mild-temperature fluidized bed gasification (MTFBG) of three high sulfur Illinois basin coals (IBC) mixed with phosphoric acid will be performed to initiate development of an advanced processing technology which partitions coal sulfur to the gas phase as H₂S. The influence of coal type, coal agglomeration, and steam injection on the properties of the solid, condensible and gaseous products produced during MTFBG will be examined. Analytical measurements of the products will be obtained and are designed to provide product quality and quantity. Combustion reactivity testing of the char, and pressurized, hot water extraction of H₃PO₄ from the char, will be performed to provide information for design of a continuous and integrated process for the removal and recovery of coal sulfur. During this quarter, the acquisition and construction of equipment to be used for MTFBG of Illinois coals and hot water, pressurized filtration of chars were completed. IBC 106 was subjected to fluidized bed gasification testing under nitrogen and steam/nitrogen atmospheres. The percentage of total sulfur removed from the parent coal using physical cleaning followed by MTFBG of coal/phosphoric acid mixtures was as high as 94% at a gasification temperature of 500°C. | |
