  • Hydrophobic zeolite modification for in situ peroxide

    Jan 10 2020 · In principle hydrogen peroxide would be an efficient oxidant for the conversion of methane to methanol under mild conditions. In practice however it is currently too expensive to produce the peroxide ahead of time for this purpose. Jin et al. report a catalyst system that generates and concentrates hydrogen peroxide for immediate reaction with methane. A hydrophobically coated zeolite

  • ZeoliteNatural and Synthetic

    The zeolite heats up releasing adsorbed water and the air becomes saturated with water. By using a suitable heat exchanger this water vapor may be condensed and the heat of condensation extracted. After the zeolite has been dehydrated it has the potential for producing heat. To extract heat moist ambient air is driven through the zeolite bed.
