Provided is a method for removing residual sulfur from a hydrotreated naphtha feedstock (1). The process comprises contacting the naphtha feedstock (1) with a first solid sulfur sorbent (2) comprising a metal on a support to thereby form a first effluent. The effluent is then contacted with a sulfur conversion catalyst in reactor (6) comprising a Group VIII metal in the presence of hydrogen, with the resulting effluent being contacted with a second solid sulfur sorbent (7) containing a Group IA or IIA metal, to thereby lower the sulfur content of the feedstock to less than 10 ppb, and to as low as 1 ppb or less. The feedstock can then be safely used with highly sulfur sensitive zeolitic reforming catalysts without adversely affecting the useful life of the catalyst. |

Process for reforming a feed composed of one or more hydrocarbon fractions comprising 9-22C comprises: at least a first reforming step, in at least one reforming unit, the charge during which a flow of hydrogen is produced; at least a first step of distillation of the effluent obtained from the reforming unit in the presence of a reforming catalyst to obtain four fractions such as a fraction of liquefied petroleum gas (LPG), 5-8C fraction of naphtha, densified 9-15C fuel fraction, and 16-22C fraction of densified diesel fuel fraction. An independent claim is included for a catalytic reforming device of a charge composed of one or more hydrocarbon fractions comprising 9-22C implementing the process comprising at least one reforming unit and at least one regeneration unit of the reforming catalyst comprising 1-6 combustion beds. |

The invention relates to a distillate fuel comprising a stable, low sulfur, highly paraffinic, moderately unsaturated distillate fuel blend stock. The highly paraffinic, moderately unsaturated distillate fuel blend stock exhibits excellent combustion properties in diesel and jet engines as a result of the high paraffin content. The blend stock is preferably prepared from a Fischer-Tropsch derived product that is hydroprocessed under conditions during which a moderate amount of unsaturates are formed or retained. The fuel blend stock comprises (a) Unsaturates in an amount between 2 and 20 weight %; (b) Sulfur in an amount less than 1 ppm; and (c) Peroxide precursors in an amount such that less than 5 ppm peroxides are formed after storage at 60 degrees C for four weeks. |

A HYDROCARBON CONVERSION PROCESS COMPRISES: (1) CONTACTING A HYDROCARBON FEED (11) SUCH AS, FOR EXAMPLE, GASOLINE, WITH A CATALYST UNDER A SUFFICIENT CONDITION TO EFFECT THE CONVERSION OF THE HYDROCARBON TO A PRODUCT STREAM COMPRISING AROMATIC HYDROCARBONS AND OLEFINS; (2) SEPARATING THE PRODUCT STREAM (13) INTO A LIGHTS FRACTION (21) COMPRISING PRIMARILY HYDROCARBONS LESS THAN 6 CARBON ATOMS PER MOLECULE, A MIDDLE FRACTION (22) COMPRISING C6-C8 AROMATIC HYDROCARBONS AND NON-AROMATIC HYDROCARBONS, AND A C9+ FRACTION (23) COMPRISING AROMATIC COMPOUNDS; (3) SEPARATING THE C6-C8 AROMATIC HYDROCARBONS FROM THE MIDDLE FRACTION; AND (4) SEPARATING HYDROCARBONS CONTAINING 5 OR MORE CARBONS PER MOLECULE (C5+ HYDROCARBONS) FROM THE LIGHTS FRACTION (21). THE C5+ HYDROCARBONS CAN BE COMBINED WITH THE HYDROCARBON FEED. THE NON-AROMATIC HYDROCARBONS CAN ALSO BE CONVERTED TO OLEFINS BY A THERMAL CRACKING PROCESS. FURTHERMORE, THE MIDDLE FRACTION (22) CAN ALSO BE OBTAINED BY REFORMING NAPHTBA. (FIGURE 1) |

The invention relates to a process for lowering the benzene content of hydrocarbon petrols. According to the invention, part of the petrol, rich in benzene, is treated in an alkylation reactor, in the presence of at least one liquid-phase olefin, for the purpose of converting benzene to alkylbenzene. The invention applies in particular to the treatment of a catalytic reforming effluent. |
