This invention has as its object a method for selective hydrogenation of a feedstock comprising a pyrolysis gasoline carried out in a three-phase reactor.

Method for the selective hydrogenation of a pyrolysis gasoline feedstock with a three-phase reactor

A process for the elimination of heavy metals, in particular mercury and possibly arsenic and lead, present in a gaseous or liquid effluent by means of a fixed bed process using an adsorbent in the form of monolithic or supported extrudates, said extrudates being characterized by a length h and a section comprising at least three lobes. The adsorbent is composed of at least one active phase based on sulphur in the elemental form or in the form of a metallic sulphide. The process is advantageously applicable to the treatment of gas of industrial origin, synthesis gas, natural gas, gas phase condensates and liquid hydrocarbon feeds.

The invention concerns a device for producing liquid hydrocarbons by Fischer-Tropsch synthesis on solid catalyst particles in a three-phase bed reactor, said device being equipped with at least one filter cartridge mounted in a filtering zone inside said reactor, said filter cartridge comprising: a filter for separating the filtrate of the solid catalyst particles, a cylindrical casing, and inner element having the shape of a hollow cylinder open at its ends and mounted substantially coaxial relative to the longitudinal axis of the casing, an annular chamber delimited by the casing and the walls of the inner element, said chamber being designed to collect the filtrate, and a discharge conduit for said filtrate, wherein the walls of the inner element of the filter cartridge are at least partly formed by the filter of the cartridge.

Device for producing liquid hydrocarbons by Fischer-Tropsch synthesis in a three-phase bed reactor

A process for the production of liquid hydrocarbons by the Fischer-Tropsch process comprises a step a) for generating a synthesis gas, a step b) for Fischer-Tropsch synthesis, a step c) for condensing the gaseous effluent obtained during step b), a step d) for separating the effluent condensed during step c) to obtain a gaseous effluent enriched in carbon monoxide and hydrogen, and a step e) for recycling at least a portion of the enriched gaseous effluent obtained during step d) to the Fischer-Tropsch synthesis step b), characterized in that:

This present invention describes a novel type of internal exchanger intended to carry out Fischer-Tropsch synthesis. This exchanger has a modular design and comprises a central tube with partitions allowing at the same time the supply of coolant to the hairpins of the module and the recovery of the partially vaporized fluid from these same hairpins.

Internal exchanger for gas-liquid-solid reactor for fischer-tropsch synthesis

The present invention describes a novel type of internal exchanger for a gas-liquid-solid fluidized bed reactor employing a strongly thermal reaction. Said exchanger is modular in concept and comprises a central tube with separations allowing both supply of cooling fluid to the pins of the module and collection of partially vaporized fluid from said same pins.
