    Abstract: A composition and process for removing sulfur from middle distillate petroleum hydrocarbon fuels. The composition includes an alumina component and a carbon component. The composition is present in an amount effective to adsorb sulfur compounds from the fuel. The alumina component and the carbon component preferably collectively comprise a composite material. The composition can further include a sulfur component, preferably a metal sulfide or sulfur oxide. The composition can also further include at least one compound having a Group VI or Group VIII metal from the periodic table.

    Abstract: The present invention discloses microporous aluminophosphate (AlPO4) molecular sieve membranes and methods for making and using the same. The microporous AlPO4 molecular sieve membranes, particularly small pore microporous AlPO-14 and AlPO-18 molecular sieve membranes, are prepared by three different methods, including in-situ crystallization of a layer of AlPO4 molecular sieve crystals on a porous membrane support, coating a layer of polymer-bound AlPO4 molecular sieve crystals on a porous membrane support, and a seeding method by in-situ crystallization of a continuous second layer of AlPO4 molecular sieve crystals on a seed layer of AlPO4 molecular sieve crystals supported on a porous membrane support. The microporous AlPO4 molecular sieve membranes have superior thermal and chemical stability, good erosion resistance, high CO2 plasticization resistance, and significantly improved selectivity over polymer membranes for gas and liquid separations, including carbon dioxide/methane (CO2/CH4), carbon dioxide/nitrogen (CO2/N2), and hydrogen/methane (H2/CH4) separations.
