Several inorganic reducing agents of various chemical characteristics have been tested to see if they reduce the oxygen contained in coal. It was found that oxygen content of coals decreased when they were heated in only water (blank runs). The treatment with the reducing agents containing sulphur did not increase the oxygen removal over that achieved in the blank runs. However, it appears that the ferrous salt catalytically deoxygenated both the lignite and bituminous coals.
