    摘要： An adsorptive separation process for separating ethanol from a feed mixture comprising ethanol and water, which process comprises contacting the feed mixture with an adsorbent comprising esterified silica selectively adsorbing substantially all of the ethanol to be separated to the substantial exclusion of the water and thereafter recovering high purity ethanol. A desorption step may be used to desorb the adsorbed ethanol.

    摘要： An improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The improvement to the adsorbent and process comprises the incorporation of a binder material in the adsorbent comprising a water permeable organic polymer which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together powder of the crystalline aluminosilicate, powders of the organic polymer binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate.

    摘要： The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2/N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2/N2 separation.

    摘要： The present invention comprises a process for removal of oxygenates from a paraffin-rich or olefin-rich paraffin stream which comprises passing a feed stream, comprising one or more C10 to C15 feed paraffins or C10 to C15 olefin-rich paraffin stream and one or more oxygenates through an adsorbent bed comprising one or more adsorbents selected from silica gel, activated alumina and sodium x zeolites to remove essentially all of said oxygenates; and recovering said paraffins. A second adsorbent bed may be employed to more thoroughly remove these oxygenates.
