Reactor for Fischer-Tropsch reaction which is carried out in a three-phase system essentially consisting of a reacting gaseous phase, a reacted liquid phase and a solid catalytic phase, wherein the solid catalytic phase consists of packed or structured bodies of catalytic material encaged within at least one honeycomb monolithic structure with a high thermal conductivity.

Reactor for exothermic or endothermic catalytic reactions

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.

Process for stabilizing the performances of a catalyst for Fischer Tropsch reaction

Process for the production of hydrogen and the co-production of carbon dioxide in separate streams comprising the following operations: feeding of a solid to a first reaction zone (R) in which a liquid or gaseous hydrocarbon, preferably natural gas or methane, is also fed, which reacts with the solid fed at its maximum oxidation degree (over-oxidized form), leading to the formation of the combustion products carbon dioxide and water and the solid at its minimum oxidation degree (reduced form); feeding of the solid in reduced form to a second reaction zone (R) into which water is also fed, which reacts with the reduced form of the solid, producing hydrogen, steam and the solid at an intermediate oxidation degree (oxidized form); feeding of the solid in oxidized form to a third reaction zone (R) into which air is also fed, obtaining, from the further oxidation of the solid, heat and the solid in over-oxidized form to be recycled to the first reaction zone (R), wherein the solid contains at least one element selected from elements which, in addition to the metallic state, have at least three different oxidation states and are therefore capable of producing two redox pairs, in order of the oxidation state, characterized in that in the first reaction zone (R) the solid in over-oxidized form and the liquid or gaseous hydrocarbon are fed in countercurrent.

Process for the production of hydrogen and the co-production of carbon dioxide

Process for the production of hydrogen consisting in subjecting a solid to oxidation and treating, in a different zone, the oxidized form thus produced with a reducing stream, preferably a hydrocarbon.
