Heat transfer in the coal gasification with nuclear reactor heat

Automatic translation: Gasification of coal means its complete conversion into gas. Depending on the gasification agent, such as steam, Oxygen, carbon dioxide or hydrogen, the product is a gas mixture with different contents of hydrogen, carbon monoxide, carbon dioxide and methane. The three first-mentioned gasification agents have long been used in industry worldwide for the production of heating and synthesis gases, while hydrogenating gasification for the production of methane as a natural gas substitute is primarily used still under development in the US The present work deals with the steam gasification of coal, which has gained a special industrial importance for the industrial gas production. Here, the coal reacts with steam to form a product gas which, in its raw state, essentially contains hydrogen, carbon monoxide, carbon dioxide and methane. Depending on the intended use, the raw gas can be processed into a heating gas or a synthesis gas. In addition to hydrogen, the latter contains others Gases in certain proportions, e.g. B. nitrogen for ammonia synthesis or carbon monoxide for methanol production.
