Abstract: A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated C10-18 oxygenate that comprises an ester group, carboxylic acid group, carbonyl group and/or alcohol group is disclosed. The process comprises contacting the feedstock with a catalyst composition comprising a metal catalyst and a heteropolyacid or heteropolyacid salt, at a temperature between about 240° C. to 280° C. and a hydrogen gas pressure of at least 300 psi. The metal catalyst comprises copper in certain embodiments. By contacting the feedstock with the catalyst composition under these temperature and pressure conditions, the C10-18 oxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the C10-18 oxygenate.

Abstract: A hydrodeoxygenation process for producing a linear alkane from a feedstock comprising a saturated or unsaturated C10-18 oxygenate that comprises an ester group, carboxylic acid group, carbonyl group and/or alcohol group is disclosed. This process comprises contacting the feedstock with (i) a catalyst comprising about 0.1% to about 10% by weight of a metal selected from Group IB, VIB, or VIII of the Periodic Table, and (ii) a heteropolyacid or heteropolyacid salt, at a temperature between about 150° C. to about 250° C. and a hydrogen gas pressure of at least about 300 psig. By contacting the feedstock with the catalyst and heteropolyacid or heteropolyacid salt under these temperature and pressure conditions, the C10-18 oxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the C10-18 oxygenate.

The process comprises contacting the feedstock with a catalyst comprising (i) about 0.1% to 10% by weight of a metal selected from Group IB or VIII of the Periodic Table, and (ii) about 0.5% to 15% by weight of tungsten, rhenium, molybdenum, vanadium, manganese, zinc, chromium, germanium, tin, titanium, gold, and/or zirconium, at a temperature between about 150° C. to 250° C. and a hydrogen gas pressure of at least 300 psig. By contacting the feedstock with the catalyst under these temperature and pressure conditions, the C10-18 oxygenate is hydrodeoxygenated to a linear alkane that has the same carbon chain length as the C10-18 oxygenate.

Abstract: Described are methods and apparatus for the selective removal of CO2 from a mixture of gases. The method comprises contacting a first gaseous mixture containing CO2 in an absorber with an absorbent having substantial selectivity for CO2, thereby forming a second mixture of absorbed CO2 and absorbent. After separating any nonabsorbed gases from the second mixture of CO2 and absorbent, the second mixture enters a separator wherein the CO2 is released from the absorbent. The absorbent is recycled back to the absorber to start the process over. The released CO2, is then compressed in one or more stages. Each stage provides a compression step to heat the released CO2, followed by a cooling step. The heat generated during the cooling of the CO2 is captured by intercoolers and recycled to operate the capture and separating process in a substantial manner, if not entirely.

Abstract: A method for recovering for a material such as an absorbed solute from an ionic liquid is described. In the method, an electric field is applied to the ionic liquid to release the absorbed solute.

Abstract: A method for capturing carbon dioxide and/or sulfur dioxide from a gaseous mixture using ionic liquid electrospray is described. In the method, the gaseous mixture is exposed to an ionic liquid electrospray plume comprising nanodroplets of an ionic liquid and the carbon dioxide and/or sulfur dioxide present in the gaseous mixture is absorbed by the ionic liquid nanodroplets. The ionic liquid electrospray plume is formed by applying an electric field between an electrospray nozzle and a counter electrode.
