GASIFICATION PROCESS FOR AMMONIA PRODUCTION

摘要

In a gasification process where coal or coke is reacted with oxygen and steam to produce a synthetic gas for making ammonia, the components for the syngas are so selected that the syngas can be used in the synthesis of ammonia without the addition of nitrogen: Instead of using oxygen to make the syngas, a mixture of oxygen and air is used as the source of oxygen, the mixture being in a ratio such that the syngas contains nitrogen and hydrogen in a molar ratio of about 1 to 3.
