APPARATUS AND METHOD FOR COAL GASIFICATION

摘要

A process and apparatus for converting a coal into a substitute natural g as generates raw gas in a conventional coal gasification unit and passes at lea st a portion of the raw gas into a partial oxidation unit to convert the at least portion of the raw gas into a secondary raw synthesis gas substantially devoid of higher hydrocarbons. Optionally, the raw gas is quenched and only the resulting condensate is passed to the partial oxidation unit for conversion to the secondary raw synthesis gas.
