Title:
METHOD FOR PRODUCING COAL GAS AND METHOD FOR PRODUCING METHANE
Document Type and Number:
WIPO Patent Application WO/2013/014995
Kind Code:
A1
Abstract:
A method for producing coal gas that includes hydrogen gas and carbon monoxide gas, using a coal gasification reactor (4) provided with a lower reaction vessel (11) and an upper reaction vessel (13), wherein the method is provided with: a step for supplying first coal, hydrogen, and water vapor to the lower reaction vessel (11), in order to cause high-temperature gas to be generated by a partial oxidation reaction; a step for supplying second coal while also introducing the high-temperature gas to the upper reaction vessel (13), in order to pyrolize the second coal; and a step for adjusting an increase or reduction in the amount of the second coal supplied to the upper reaction vessel (13), in order to control to 1,000°C or higher the temperature of coal gas flowing out from an outlet of the upper reaction vessel (13).
