New Developments (II-b). 3. Partial Oxidation and Other Methods.
Ch in Ammonia I 2:347-353
The general low cost and widespread use of natural gas and naphtha have discouraged research and development on coal gasification in most of the countries that have large coal reserves. An exception is the United States, where extensive research was begun in the 1960's--mainly under sponsorship of the Bureau of Mines office of coal research--to develop a pipeline gas as a substitute for natural gas. Other work has been aimed at making synthesis gas or hydrogen for use as an intermediate in making liquid fuels from coal. Either type is suitable for making ammonia synthesis gas if the process can be adjusted to give the gas composition required. This chapter describes efforts of the Bureau of Mines toward these ends.
