Process for the purification of an aqueous stream coming from the Fischer-Tropsch reaction which comprises: feeding said aqueous stream containing the organic by products of the reaction to one or more pervaporation units, said one or more pervaporation units comprising at least one polymeric pervaporation membrane, obtaining two outgoing streams: &#x2014;an aqueous stream (i) enriched in alcohols having from 1 to 8 carbon atoms, preferably from 2 to 4 carbon atoms; &#x2014;an aqueous stream (ii) enriched in water.

Partial oxidation process of liquid fuels, selected from hydrocarbon and/or oxygenated compounds, together with gaseous fuels, selected from hydrocarbon compounds, natural gas and LPG, by means of a suitable catalytic system comprising the following steps: premixing the reagents and possibly heating them to temperatures ranging from 25 to 400&#xb0; C., said reagents consisting of said liquid fuels, said gaseous fuels and oxygen or air or oxygen enriched air, optionally in the presence of vapor and/or CO; reacting the mixture of reagents in the catalytic zone, at inlet temperatures ranging from 50 to 500&#xb0; C. and space velocities ranging from 1,000 to 1,000,000 Nl reagents/L cat&#xd7;h, reaching temperatures ranging from 450 to 1350&#xb0; C.

Catalytic partial oxidation process for producing synthesis gas

Hydrocarbons are prepared, liquid at the reaction temperature, by feeding synthesis gas into three-phase turbulent reactors in which the solid phase, consisting of the catalyst in the form of particles, is kept in suspension in the liquid phase by the rising synthesis gas. The reaction product is separated/filtered in continuous from the catalyst dispersed therein by means of at least one filtration device consisting of a hydrocyclone over which there is a first hollow metal element in which a second hollow element is situated, coaxial with the first, made of a material having a porous structure, with an average pore diameter ranging from 0.002 to 0.1 micrometers, suitable for micro/ultrafiltration.

Process for the production in continuous of hydrocarbons from synthesis gas in slurry reactors and for the separation of the liquid phase produced from the solid phase

Hydrocarbons are prepared, liquid at the reaction temperature, by feeding synthesis gas into three-phase turbulent reactors wherein the solid phase, consisting of the catalyst in particle form, is kept in suspension in the liquid phase by the rising synthesis gas. The reaction product is separated/filtrated in continuous from the catalyst dispersed therein, by means of a separation/filtration unit consisting of several filtration cartridges, each consisting of at least two porous filtering elements, the first having an average pore diameter ranging from 0.5 to 15 &#x3bc;m, whereas the second has an average pore diameter ranging from 0.002 to 0.1 &#x3bc;m.
