Title:
二酸化炭素からのメタンの製造方法
Document Type and Number:
Japanese Patent JP4214218
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing methane from carbon dioxide and to provide a catalyst used therefor. SOLUTION: A catalyst is obtained by adding a cationic organic compound into a hydrous oxide expressed by general formula (1): Si4-x Alx M<2+> y O8-x/2+y-z/2 (OH)2 .nH2 O (in the formula, (x) is 0<=x<=0.8, (y) is 2.2<=y<=3.0, (z) is 2.0<=z<=4.5, (n) satisfies the relation of indefinite ratio and M<2+> represents Ni<2+> or one of bivalent metallic ion of Ni<2+> and Mg<2+> ), hydrothermally treating and calcining in the air at 100-1,000 deg.C. The method of manufacturing methane from carbon dioxide is performed by reducing the 3-octahedral smectite like synthetic porous body of the resultant catalyst with hydrogen at 200-600 deg.C to use as a catalyst and bringing a gas containing substantially no carbon monoxide and containing carbon dioxide and hydrogen into contact with the catalyst to produce methane.
