  • 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: 8992670
    Abstract: A method for removing one or more volatile organic compounds (VOCs) from a gas stream, in which the method includes adsorbing one or more of the gaseous volatile organic compounds (VOCs) on a granular activated carbon (GAC) obtained from date palm pits. The granular activated carbon is obtained by a process of: cutting the date palm pits into particles; mixing the particles with an acid solution to form soaked date palm pits; transferring the soaked date palm pit particles to stainless steel tubes; heating the tubes inside a muffle furnace; transferring the tubes to a desiccator and cooling; washing the granular activated carbon samples with water and drying; and sieving the samples. The obtained GAC is successfully tested under dynamic continuous gas flow conditions for gas phase benzene removal under a varying set of conditions including different gas phase benzene concentrations.

  • Patent number: 8961819
    Abstract: Disclosed herein provide compositions and hydrogen release methods for a high-capacity complex hydrogen storage material. The hydrogen storage material is mainly composed of metal borohydride and NH3. The invention advantageously adopt ammonia, one cheap and easily supplied material with high hydrogen content (17.6 wt %), as one of the hydrogen source, offering a safe and efficient way to store hydrogen and release hydrogen. Furthermore, the hydrogen storage material can be further catalyzed by a transition metal catalyst to improve the dehydrogenation kinetics. With the addition of catalyst, 0.2-10 equiv. H2 could be evolved at ?100˜600° C., which might be applied on vehicles which are fueled by hybrid or fuel cell.

  • Publication number: 20150050494
    Abstract: A multi-walled titanium-based nanotube array containing metal or non-metal dopants is formed, in which the dopants are in the form of ions, compounds, clusters and particles located on at least one of a surface, inter-wall space and core of the nanotube. The structure can include multiple dopants, in the form of metal or non-metal ions, compounds, clusters or particles. The dopants can be located on one or more of on the surface of the nanotube, the inter-wall space (interlayer) of the nanotube and the core of the nanotube. The nanotubes may be formed by providing a titanium precursor, converting the titanium precursor into titanium-based layered materials to form titanium-based nanosheets, and transforming the titanium-based nanosheets to multi-walled titanium-based nanotubes.
