  • Patent number: 9034274
    Abstract: The present invention relates to a vehicular air cleaner. A DOR (Direct Ozone Reduction) system for suppressing deterioration of a purifying function of an ozone purifying material is provided. Active oxygen is produced by an ozone purifying function of activated carbon. The probability that the active oxygen contacts with a fin of a radiator on a rear surface side is higher than that on a front surface side of the radiator. Accordingly, the activated carbon on the rear surface side of the radiator is easily oxidized as compared with the activated carbon on the front surface side. Therefore, in the fin, a coating amount of the activated carbon on the front surface side of the radiator is adjusted to be larger than a coating amount of the activated carbon on the rear surface side. Thus, the probability that the active oxygen contacts with the activated carbon can be reduced.

  • Patent number: 7585406
    Abstract: A Process for hydroconverting of a heavy hydrocarbonaceous feedstock comprising a catalyst to produce lower boiling hydrocarbon products. The method can be used for the high- boiling point residues of oil refining (asphaltene, the residues of vacuum and under pressure distillation of oil, and the useless and heavy materials of thermo catalytic processes), heavy oil, natural bitumen, and bitumen-containing sands. It can also be used in oil refinery industries for the production of gas, gasoline fractions, distillation gas oil, concentrate of ash containing metals and chemical fertilizers.

  • Patent number: 7569508
    Abstract: Reforming nanocatalysts are formed using a dispersing agent to increase the activity, selectivity and longevity of the catalyst when used in a reforming process. The nanocatalyst particles are formed using a dispersing agent having at least one functional group selected from the group of a hydroxyl, a carboxyl, a carbonyl, an amide, an amine, a thiol, a sulfonic acid, sulfonyl halide, an acyl halide, an organometallic complex, and combinations of these. The dispersing agent is particularly useful for forming multicomponent catalysts comprising an alloy, combination, mixture, decoration, or interspersion of platinum and one or more of tin, rhenium or iridium. The formation of the nanoparticles may include a heat treating process performed in an inert or oxidative environment to maintain the catalyst atoms in a non-zero oxidation state to thereby maintain a stronger bond between the dispersing agent and the catalyst atoms.

  • Patent number: 7449423
    Abstract: A catalyst manufacturing process includes heat treating an intermediate catalyst composition that includes catalyst nanoparticles having catalyst atoms in a non-zero oxidation state bonded to a dispersing/anchoring agent. The catalyst nanoparticles are formed using a dispersing agent having at least one functional group selected from the group of a hydroxyl, a carboxyl, a carbonyl, an amide, an amine, a thiol, a sulfonic acid, sulfonyl halide, an acyl halide, an organometallic complex, and combinations of these. The dispersing agent can be used to form single- or multicomponent supported nanocatalysts. The dispersing agent also acts as an anchoring agent to firmly bond the nanocatalyst to a support. Performing the heat treating process in an inert or oxidative environment to maintain the catalyst atoms in a non-zero oxidation helps maintains a stronger bonding interaction between the dispersing agent and the catalyst atoms.
