National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

PB261306

Publication Date	1976
Personal Author	Raymon, N. S.; Sadler, L. Y.
Page Count	32
Abstract	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.
