Title:
METHOD FOR PRODUCING FUEL GAS AND DEHYDRATION-HYDROGENATION CATALYST OF ALCOHOL
Document Type and Number:
Japanese Patent JP2022133257
Kind Code:
A
Abstract:
To provide a method for obtaining a fuel gas with a reduced hydrogen concentration by a simple and economically advantageous method when producing the fuel gas containing methane as a main component, and a catalyst necessary for realization of the method.SOLUTION: A method for producing a fuel gas comprises: a methanation reaction step of reacting hydrogen and carbon oxides under the presence of a methanation catalyst to obtain a first fuel gas containing 2% or more to 20% or less of hydrogen on a volume basis after dehydration; and a dehydration-hydrogenation reaction step of adding an alcohol to the fuel gas obtained in the methanation reaction step, and then reacting the alcohol with hydrogen in the first fuel gas in the presence of a dehydration-hydrogenation catalyst to obtain a second fuel gas containing an alkane having 2 to 4 carbon atoms, wherein the alcohol is one or more alcohols selected from alcohols having 2 to 4 carbon atoms, and the dehydration-hydrogenation catalyst is formed by supporting palladium on zirconia tungsten oxide, and has activity in a dehydration reaction of the alcohol and a hydrogenation reaction of an alkene.SELECTED DRAWING: Figure 1
