A reactor for Fischer-Tropsch reaction effected in a three-phase system essentially consisting of a gaseous reagent phase, a liquid reacted phase and a solid catalytic phase, wherein the solid catalytic phase is composed of packed bodies encaged in at least one open-cell foam structure with a high thermal conductivity.

Packed-bed tubular reactor for heterogeneous exothermic or endothermic catalytic reactions

A method is described for optimizing the operation of a reaction section for the synthesis of hydrocarbons from a feed comprising synthesis gas, operated in the presence of a catalyst comprising cobalt, said method comprising the following steps:

Method for optimizing the operation of a hydrocarbon synthesis unit starting from synthesis gas, by controlling the partial pressure of CO

Process for maintaining the stability of performances of a catalyst for Fischer-Tropsch reaction, performed in a slurry bubble column reactor under a triphase system which comprises gradually increasing the P/Pratio and the P/Z ratio, during the start-up phase, with Z=&#xb7;(T/T)&#xb7;efrom 0.4 to 0.8, for a period of time not shorter than 100-150 hrs and not longer than 200-300 hours and, at the end of the start-up phase, maintaining the P/Pand P/Z ratios substantially equal to or lower than 0.8.
