| 20110108457 | PROCESS FOR RECOVERING FCC PRODUCT - A process is disclosed for recovering product from catalytically converted product streams. Gaseous unstabilized naphtha from an overhead receiver from a main fractionation column is compressed in a compressor. Liquid unstabilized naphtha from the overhead receiver and liquid naphtha fraction from the compressor are sent to a naphtha splitter column upstream of a primary absorber. Consequently, less naphtha is circulated in the gas recovery system. | 05-12-2011 |

| 20110243797 | APPARATUS FOR OLIGOMERIZING DILUTE ETHYLENE - The apparatus converts ethylene in a dilute ethylene stream that may be derived from an FCC product to heavier hydrocarbons. The oligomerization reactor is in communication between a primary absorber column and a secondary absorber column in an FCC product recovery section. The oligomerization catalyst may have a low silica base with a Group VIIIB metal and operate at low pressure without excessive deactivation. The catalyst is resistant to feed impurities such as hydrogen sulfide, carbon oxides, hydrogen and ammonia. At least 40 wt-% of the ethylene in the dilute ethylene stream can be converted to heavier hydrocarbons. | 10-06-2011 |
| 20110243799 | APPARATUS FOR INCREASING WEIGHT OF OLEFINS - The apparatus converts FCC olefins to heavier compounds. The heavier compounds are more easily separated from the unconverted paraffins. The heavier compounds can be recycled to an FCC unit or delivered to a separate FCC unit. Suitable conversion zones are oligomerization and aromatic alkylation zones. | 10-06-2011 |

| 20110319698 | PROCESS FOR UPGRADING SWEETENED OR OXYGEN-CONTAMINATED KEROSENE OR JET FUEL, TO MINIMIZE OR ELIMINATE ITS TENDENCY TO POLYMERIZE OR FOUL WHEN HEATED - A process is presented for the removal of oxygen from a hydrocarbon stream. The oxygen can react and cause polymerization of the hydrocarbons when the hydrocarbon stream is heated. Controlling the removal of the oxygen from the hydrocarbon stream produces a hydrocarbon stream that is substantially free of oxygen and has a reduced activity for generating undesired compounds. | 12-29-2011 |
| 20130079570 | METHODS FOR CO-PRODUCTION OF ALKYLBENZENE AND BIOFUEL FROM NATURAL OILS USING HYDROCRACKING - Embodiments of methods for co-production of linear alkylbenzene and biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C | 03-28-2013 |
| 20130131417 | METHODS AND SYSTEMS FOR OLEFIN PRODUCTION - One example method of the invention includes a process for producing an olefin comprising the steps of communicating a feed stream that comprises a paraffin to a distillation section, communicating a distillation section output stream to a reactor and reacting the distillation section output stream in the reactor to produce a reactor output stream comprising an olefin. | 05-23-2013 |
