The present invention describes a type of inclined bed reactor which permits a small quantity of catalyst to be employed. Application of the reactor to a regenerative reforming process.

Inclined bed reactor permitting a small quantity of catalyst to be employed

The present invention concerns a process for the production of light olefins and BTX using a catalytic cracking unit, NCC, processing a naphtha type feed, and an aromatics complex. It can be used to exploit the synergies between these two units. The thermal balance of the NCC, which is intrinsically deficient in coke, is resolved by the optimal use of heat from the reforming furnaces in order to preheat the feed for the NCC, and by introducing at least a portion of the raffinate obtained from the aromatics complex as a mixture with the naphtha.

The present invention relates to the FCC units processing heavy feedstocks enriched with hydrogen, such as for example a highly hydrotreated VGO, or the unconverted part at the end of hydrocracking this same type of VGO feedstock, feedstocks which have the characteristic of cracking to light olefins such as ethylene and propylene. The integration of an FCC with an aromatic complex allows the recovery by the aromatic complex of the BTX formed in the FCC, and the recovery by the FCC from the flow at the bottom of the column, of heavy aromatics from the aromatic complex.

A process for reforming a feed composed of one or more hydrocarbon cuts containing 9 to 22 carbon atoms which includes, at least one first step for reforming the feed in at least one reforming unit, during which a stream of hydrogen is produced and at least one first step for distillation of the effluent from the reforming unit in the presence of a reforming catalyst in order to obtain 4 cuts. The 4 cuts are, a liquefied petroleum gas cut (LPG) (A), a C-Ccut: naphtha (B), a C-Ccut: densified kerosene (C), and a C-Ccut: densified gas oil cut (D). The invention also concerns the device for carrying out this process.
