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

A process for recovering metals from a stream rich in hydrocarbons and carbonaceous residues by means of a treatment section, characterized in that it comprises the following steps: sending said stream to a primary treatment, effected in one or more steps, wherein said stream is treated in the presence of a fluxant agent in a suitable apparatus, at a temperature ranging from 80 to 180&#xb0; C., preferably from 100 to 160&#xb0; C., and subjected to liquid/solid separation in order to obtain a clarified product essentially consisting of liquids and a cake (oilcake); possibly subjecting the separated cake to drying, in order to remove the hydrocarbon component having a boiling point lower than a temperature ranging from 300 to 350&#xb0; C. from the cake; sending the cake, possibly dried, to a secondary thermal treatment comprising: a flameless pyrolysis of the cake effected between 400 and 800&#xb0; C., preferably between 500 and 670&#xb0; C.; an oxidation of the pyrolysis residue effected in an oxidizing environment and at temperatures ranging from 400 to 800&#xb0; C., preferably from 500 to 700&#xb0; C.

A process is described for improving the quality as a fuel of hydrotreated hydrocarbon blends by reaction with hydrogen in the presence of a bifunctional catalytic system comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re, and a silico-aluminate of an acidic nature, selected from a micro-mesoporous silico-alumina and a zeolite belonging to the MTW family. The process of the invention produces an increase in the cetane index and a decrease in the density and T95.

Process for producing mixtures of methanol and higher alcohols comprising feeding, into the reaction zone equipped with a catalytic system, H.sub.2, CO and possibly inert products with a molar ratio H.sub.2 /CO of between 0.2 and 10, at a temperature of between 200.degree. and 460.degree. C., at a pressure of between 2,000 and 30,000 KPa, and at a space velocity of between 1,000 and 40,000 GHSV, wherein the catalytic system corresponds to the following empirical formula:
