| 20090107032 | PRODUCTION OF LOW SULPHUR ALKYLATE GASOLINE FUEL - A method for producing a low sulphur containing fuel from a hydrocarbon feed having from 10 to 80 ppm of sulphur is disclosed. The method comprises contacting a hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms and at least one paraffin having from 4 to 6 carbon atoms with an ionic liquid catalyst and a halide containing additive in an alkylation reaction zone under alkylating conditions to produce a fuel having sulphur content up to 10 ppm. | 04-30-2009 |
| 20090163349 | REMOVAL OF EXCESS METAL HALIDES FROM REGENERATED IONIC LIQUID CATALYSTS - A process for removing metal halides from regenerated ionic liquid catalyst comprising interacting a regenerated ammonium-based metal-halide ionic liquid catalyst or an ammonium-based metal-halide ionic liquid catalyst undergoing regeneration with either the parent ammonium halide salt from which the ionic liquid catalyst was made or a corresponding mixed salt having an ammonium halide to metal halide molar ratio of 0 to less than 2.0 is disclosed. | 06-25-2009 |
| 20090192339 | ISOMERIZATION OF BUTENE IN THE IONIC LIQUID-CATALYZED ALKYLATION OF LIGHT ISOPARAFFINS AND OLEFINS - A process for producing alkylate comprising contacting a first hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms which contains 1-butene with an isomerization catalyst under conditions favoring the isomerization of 1-butene to 2-butene so the isomerized stream contains a greater concentration of 2-butene than the first hydrocarbon stream and contacting the isomerized stream and a second hydrocarbon stream comprising at least one isoparaffin having from 3 to 6 carbon atoms with an acidic ionic liquid catalyst under alkylation conditions to produce an alkylate stream is disclosed. | 07-30-2009 |
| 20100130804 | ELECTROCHEMICAL REMOVAL OF CONJUNCT POLYMERS FROM CHLOROALUMINATE IONIC LIQUIDS - A process for regenerating a spent ionic liquid catalyst including (a) applying a voltage across one or more pairs of electrodes immersed in a spent ionic liquid catalyst comprising conjunct polymer-metal halide complexes to provide freed conjunct polymers and a regenerated ionic liquid catalyst; and (b) separating the freed conjunct polymers from the regenerated ionic liquid catalyst is described. An alkylation process incorporating the regeneration process is also described. | 05-27-2010 |
| 20100147740 | RECOVERY AND USE OF CONJUNCT POLYMERS FROM IONIC LIQUID CATALYSTS - A process comprising regenerating a used ionic liquid catalyst, recovering conjunct polymer from the regenerated catalyst and using at least a portion of the conjunct polymer is disclosed. | 06-17-2010 |
| 20100147746 | REDUCTION OF ORGANIC HALIDE CONTAMINATION IN HYDROCARBON PRODUCTS - A method for reducing halide concentration in a hydrocarbon product having an organic halide content which is made by a hydrocarbon conversion process using a halogen-containing acidic ionic liquid catalyst comprising contacting at least a portion of the hydrocarbon product with an aqueous caustic solution under conditions to reduce the halide concentration in the hydrocarbon product is disclosed. | 06-17-2010 |
| 20110092753 | HYDROISOMERIZATION AND SELECTIVE HYDROGENATION OF FEEDSTOCK IN IONIC LIQUID-CATALYZED ALKYLATION - A process for producing alkylate comprising contacting a first hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms which contains 1,3-butadiene and 1-butene with a hydroisomerization catalyst in the presence of hydrogen under conditions favoring the simultaneous selective hydrogenation of 1,3-butadiene to butenes and the isomerization of 1-butene to 2-butene and contacting the resulting stream and a second hydrocarbon stream comprising at least one isoparaffin having from 3 to 6 carbon atoms with an acidic ionic liquid catalyst under alkylation conditions to produce an alkylate is disclosed. | 04-21-2011 |
| 20110130602 | PROCESS FOR REACTING ISO-ALKANE - A process for reacting an iso-alkane, comprising:
| 06-02-2011 |
| 20110144399 | PROCESS FOR PRODUCING ALKYLATE WITH AN INCREASED RON - A process for producing alkylate comprising contacting a first hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms which contains 1-butene with an isomerization catalyst under conditions favoring the isomerization of 1-butene to 2-butene so the isomerized stream contains a greater concentration of 2-butene than the first hydrocarbon stream and contacting the isomerized stream and a second hydrocarbon stream comprising at least one isoparaffin having from 4 to 6 carbon atoms with an acidic ionic liquid catalyst under alkylation conditions to produce an alkylate stream, wherein the alkylate stream has a RON that is increased from 5 to 32 numbers compared to a comparison alkylate stream made from the first hydrocarbon stream without the step of contacting with the isomerization catalyst. | 06-16-2011 |
