Abstract: Catalyst for ren. of N oxides is industrial combustion gases with gaseous ammonia is selected from CuO and Fe2O3 and can be combined with an active alumina carrying Cr2O3. The catalyst system is pref. preliminarily treated with N2 or air contg. 50-2000 ppm SO2 at 200-450 degrees C, whereby the redn. of catalytic activity caused by moisture is eliminated (alternatively, the effluent gases may contain 50-1400 ppm SO2). The catalytic activity is stabe even at high temps. This catalyst system is cheaper than prior art systems.

Abstract: PURPOSE:To increase reactive selectivity by permitting a catalyst carrier consisting of spinel crystal to carry transition metal selected from among Mo, Co, Ni and W as a catalytic activate component and thereby forming a catalyst for hydrogenation. CONSTITUTION:The carrier is made from an aq. nitrate solution 2 or 3 elements selected among Al, Mg, Co, Ni and Ga, mixed them stoichiometrically so as to form the spinel crystalline structure and spray thermal decomposed it. And catalytic active elements such as Mo, Ni, Co, W are carried on the carrier and they are strongly bonded with Al in the carriers. The preferable dose of carried transition metal is 0.01-80wt.%. The catalyst obtained provides uniform mutual action between the activated metal and the carrier, as the carrier has a stable constitution and subsequently forms a uniform active site on the surface easily.

Abstract: PROBLEM TO BE SOLVED: To obtain a hydrogenating catalyst having high hydrogenating function for an aromatic or heterocyclic ring, resistance against a sulfur compd. and a nitrogen compd. and long life by supporting palladium and platinum on an ultra-stabilized Y-type zeolite carrier modified by heavy rare earth elements. SOLUTION: As a carrier for supporting Pd and Pt components, an ultra- stabilized Y-type zeolite (carrier zeolite) modified by heavy rare earth elements is used. The SiO2/Al2O3 molar ratio of this carrier zeolite is about 5.0-1,000, pref., about 10-20 and, as the heavy rare earth elements, there are four elements, that is, ytterbium(Yb), gadolinium(Gd), terbium(Tb) and dysprosium(Dy). In order to modify the ultra-stabilized Y-type zeolite, at least one element selected from these heavy rare earth elements is used. Only one of palladium and platinum may be supported on the carrier zeolite but both of them are pref. supported thereon.

Abstract: PROBLEM TO BE SOLVED: To obtain a bactericidal agent which can simply and safely killing bacteria in water by using a specific allophane as an active ingredient. SOLUTION: This bactericide contains, as an active ingredient, a silver- containing allophane prepared by substituting the H atom in the OH group in allophane represented by the formula ((a), (b) and (c) are each mole number, H binds to the oxygen in the structure to form OH, a/b=1-2; c/b=2.5-3). In addition, a part of OH on the surface of allophane particles may be substituted with a phosphoric acid group and a part of H of the OH may be substituted with silver ion, namely may contain a phosphorus and silver-containing allophane. This composition-modified allophane bactericide is brought into contact with water or a moisture-containing gas to be treated whereby the water or moisture-containing gas is disinfected by the surface of the bactericide.

Abstract: PROBLEM TO BE SOLVED: To obtain a hydrogenation catalyst which exhibits an excellent denitrification activity, a high degradation resistance, and a long life by causing a fibrous alumina carrier having a specified average length to carry a metal selected from among metals of the groups VIA and VIII. SOLUTION: The medium-gravity distillate of a coal liquefaction oil is a coal-derived hydrocarbon oil having a b.p. in the range of 100-350 deg.C, and heavy naphtha, kerosene, a gas oil distillate, etc., belong to this category. The fibrous alumina carrier is bundles of fibrous alumina particles having an average length of 5-15 nm, The hydrogenation catalyst is prepared by causing the fibrous alumina carrier to carry a metal selected from among metals of the groups VIA and VIII by a conventional method such as impregnation, immersion or kneading. The metal is e.g. molybdenum, tungsten, cobalt or nickel, tungsten or nickel being especially preferable. The amount of a metal (as an oxide) carried is preferably 20-35 wt.% in the case of a group VIA metal and 3-5 wt.% in the case of a group VIII metal.

Abstract: PURPOSE:To obtain a highly active hydrogenation catalyst by depositing a catalytic metal on a carrier and dry-sulfurating the metal without calcining it. CONSTITUTION:Catalytic metals such as molybdenum, cobalt and nickel are singly or plurally deposited on a carrier of gamma-alumina, etc. The metals are heated, dehydrated and sulfurated in a reducing atmosphere without being calcined and without the metal salts depositing on the catalyst surface being converted to their oxides to obtain different surface structures. Heavy hydrocarbons are hydrogenated and efficiently reformed or cracked by the catalyst thus obtained.

Abstract: PURPOSE:To obtain a catalyst capable of keeping stable activity over a long period of time by using zeolite having one or more metal atom in its cage and allyl mercaptan or thioglycolic acid being a sulfiding agent. CONSTITUTION:Zeolite containing one or more metal atom of the Group V1a of the Periodic Table in its cage and alumina are kneaded and molded. Subsequently, the molded one is dried to be baked and impregnated with allyl mercaptan or thioglycolic acid in an amount necessary for converting said metal atom to oxide and dried to obtain in a hydrogenating catalyst for hydrocarbon oil. As the alumina source, there are gamma-alumina or alumina hydrate. As a metal of the Group V1a of the Periodic Table, there are molybdenum or tungsten but molybdenum is proper from the aspect of catalytic activity or cost. When molybdenum is introduced into the cage of zeolite to form molybdenum disulfide or a precursor thereof in the cage, the flocculation of molybdenum disulfide during the hydrotreatment of hydrocarbon oil can be prevented and activity stable over a long period of time can be kept.
