The Institute of Gas Technology (IGT) has developed the U-GAS process to produce a low- or medium-Btu gas (U-GAS) from different types of coal feed stocks. The process uses a combination of fluidized-bed gasification and ash agglomeration in a single-stage reactor. A 30 tons per day capacity pilot plant has been used to develop the process. Feedstocks ranging from unreactive coke to peat have been gasified successfully in the same pilot plant, indicating its ability to handle a wide variation in feedstock properties. An extensive data base for design and scale-up to a larger size gasifier has been developed in the pilot plant. Recent tests have investigated the possibilities of innovative sulfur and particulate cleanup from the raw product gas. These developments improve the economics of the process, especially for application of the gas as a fuel and for combined-cycle power generation. Activities related to commercialization of the U-GAS technology are proceeding in several countries. This is the second paper on the U-GAS process to be presented at the Advanced Coal Gasification Symposium Series of the People's Republic of China. In this paper, the results of recent pilot-plant tests are presented, and the supporting technical programs being conducted at IGT to broaden the technology base are described. 13 figs.
