Abstract: The present invention relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with an ethylene oxide capped glycol ether described by the structure: RO—(CH2CH(CH3)O)m(C2H4O)nH wherein R is a linear, branched, cyclic alkyl, phenyl, or alkyl phenyl group of greater than 5 carbons and m and n are independently 1 to 3.
Abstract: A process for converting a feed stream to C2 to C5 hydrocarbons includes introducing a feed stream of hydrogen and at least one carbon-containing component selected from CO, CO2, and mixtures thereof into a reaction zone at an initial reactor pressure and an initial reactor temperature. The feed stream is contacted to a hybrid catalyst positioned in the reaction zone, and the hybrid catalyst includes a methanol synthesis component and a solid microporous acid material. The pressure within the reaction zone is increased during the contacting of the feed stream to the hybrid catalyst from the initial reactor pressure to a final reactor pressure. A temperature within the reaction zone at any time during the contacting of the feed stream to the hybrid catalyst is within±20° C. of the initial reactor temperature.

Abstract: An asymmetric polyvinylidene chloride copolymer membrane is made by a method using a dope solution comprised of a polyvinylidene chloride copolymer and a solvent that solubilizes the polyvinylidene chloride copolymer that is shaped to form an initial shaped membrane. The initial shaped membrane is then quenched in a liquid comprised of a solvent that is miscible with the solvent that solubilizes the polyvinylidene chloride copolymer but is immiscible with the polyvinylidene chloride copolymer to form a wet asymmetric polyvinylidene chloride copolymer membrane. The solvents are removed from the wet membrane to form the asymmetric polyvinylidene chloride (PVDC) copolymer membrane. The membrane then may be further heated to form a carbon asymmetric membrane in which the porous support structure and separation layer of the PVDC membrane is maintained.
