The present invention describes a thin layer fixed bed reactor intended for chemical treatments, in particular reduction of a Fischer-Tropsch synthesis catalyst. The reactor is designed in the form of similar, compact modules and operates with a ratio of linear pressure drop to outlet pressure which falls within certain limits.

Thin layer fixed bed reactor for the chemical treatment of a finely divided catalytic solid

A process in which the paraffinic effluent derived from a Fischer-Tropsch synthesis unit is separated to obtain a heavy C+ fraction, said heavy fraction then being hydrogenated in the presence of a hydrogenation catalyst at a temperature in the rangeC to&#xb0; C, at a total pressure in the rangetoMPa, at an hourly space velocity in the rangeto, and at a hydrogen flow rate corresponding to a hydrogen/hydrocarbons volume ratio in the rangetoNI/I/h, the liquid hydrogenated effluent then being brought into contact with a hydroisomerization/hydrocracking catalyst, with no prior separation step, the hydroisomerized/hydrocracked effluent then being distilled to obtain middle distillates and possibly oil bases.

Process for producing middle distillates by hydroismerizing and hydrocracking a heavy fraction from a fischer-tropsch effluent

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.
