  • Patent number: 11571651
    Abstract: The invention relates to the intensification of hydrogen PSA processes through utilization of specifically engineered core-shell composite adsorbents. Different embodiments of core-shell adsorbents can be used with either high or low heat capacity cores, and different adsorbent shells (e.g. activated carbon, zeolite, silica gel, alumina etc.) resulting in higher mass transfer rates and hence sharper mass transfer fronts during the PSA process. The location of the limiting impurity front determines the product purity. Therefore, with sharper impurity fronts, lower height of adsorbent bed is required, and cycle time can be proportionally reduced. Also, thermal swing during the PSA can be reduced by use of such adsorbents. The use of a high heat capacity core to reduce the thermal swing, leads to higher overall working capacity of the adsorbent bed.

  • 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.
