IC 8721 Refractory Lining Materials For Coal Gasifiers - A Literature Review Of Reactions Involving High-Temperature Gas And Alkali Metal Vapors

As part of an interegency agreement with the Energy Research end Development Administration to develop unproved refractory materials for use in coal gasification processes, the Bureau of Mines reviewed the literature to determine the effect of steam, H2, CO, and CH4 as well as the alkali metal oxides K2O and Na2O on refractory materials. Emphasis was given to the performance of high-alumina castable and fired refractories to conditions expected in coal gasification processes. Approximately 85 references were reviewed with 40 cited in the text. The literature was found to contain little data directly applicable to the selection of refractory lining materials suitable for use under the conditions of temperature, pressure, and gas compositions expected in second generation coal gasification reactors.
