Abstract: A fuel cell system is provided with: a fuel supplier supplying a fuel including dimethyl ether; a reforming catalyst causing a reforming reaction of the fuel into a reformed gas including hydrogen; a shift catalyst causing a shift reaction of the reformed gas; a methanation catalyst causing a methanation catalyst of the reformed gas; a hydrogenation catalyst causing a hydrogenation catalyst of the reformed gas; and a fuel cell using hydrogen formed the reforming reaction and the shift reaction from the fuel and oxygen included in an atmospheric air to generate electricity.

Abstract: A solution of a chromium compound is impregnated into a silica-alumina carrier made of alumina and containing 1 to 5 weight % of silica relative to the weight of the carrier, thereby to obtain a decomposing catalyst carrying 10 to 15 weight % of chromium oxide relative to the weight of the catalyst in terms of Cr2O3. By contacting mixed gas obtained through partial oxidation of heavy oil and/or coal with the decomposing catalyst, COS and HCN contained in the mixed gas are decomposed/removed. In this case, transition of alumina into boehmite can be suppressed owing to coexistence of silica and chromium oxide, so that COS and HCN can be decomposed by highly active catalytic reactions over a long time.

Abstract: A catalyst for the nonoxidative production of alkenylaromatics from alkylaromatics, wherein the catalyst is predominantly iron oxide, an alkali metal compound, copper oxide, cerium oxide and less than about 100 ppm of a source for a noble metal, such as palladium, platinum, ruthenium, rhenium, osmium, rhodium or iridium. Additional components of the catalyst may include compounds based on molybdenum, tungsten, calcium, magnesium, chromium and other such promoters.

Abstract: The invention has an object to provide a solid chloride absorbent which can efficiently absorb inorganic chlorides such as hydrogen chloride flowing out from a process in which a heavy naphtha and the like are treated and inorganic chloride derived from crude oil, and which is difficult to powder and soften after absorbing the chlorides. The solid chloride absorbent according to the invention comprises zinc oxide, a porous refractory inorganic matter and an inert binder, has a long life, and hardly releases the absorbed chlorides.
