Abstract
A partial combustion process wherein a substantial portion of the soot formed in the combustion reactor is separated from the crude gas, e.g., by hot cyclones, and burned in a separate combustion zone with an excess of oxygen, optionally in the presence of steam, to yield a hot gas containing oxygen, carbon dioxide and water. This hot gas product, dependent on the ash content of the hydrocarbon feed is then subject to an optional solids removal step prior to its introduction into the partial combustion reactor where the oxygen contained therein supplies at least a portion of the oxidant requirement for partial oxidation and the carbon dioxide and water present therein are substantially converted to carbon monoxide and hydrogen.
