    Abstract: A process for the catalytic reforming of a hydrocarbon charge wherein the charge passes successively through at least two catalyst beds, the first one being a bed of a first catalyst whose carrier contains platinum, rhenium and at least one halogen, at least the last bed being a moving bed of a second catalyst whose carrier contains platinum, at least one additional metal M selected from the group consisting of tin, gallium, germanium, indium, lead and thallium and at least one halogen, said metal M being introduced onto this carrier by means of an organometallic compound and the proportion by weight of said second catalyst being from 25 to 55% of the total catalyst mass used in all the catalyst beds. The charge preferably passes through at least two fixed beds of the first catalyst and at least one moving bed of the second catalyst, the carrier of the two catalysts being preferably alumina.By this process high grade gasolines (of Research Octane Number higher than 95) are produced over long periods.

    Abstract: A fresh charge containing aromatic hydrocarbons is hydrotreated in admixture with a recycle fraction, in the presence of a bifunctional catalyst, a portion of the effluent is subjected to steam-cracking, thereby recovering a gas oil fraction which is subjected to hydrogenation and forms said recycle fraction. The mixture of recycle fraction and charge is advantageously treated with hydrogen in the presence of a monofunctional catalyst to hydrogenate olefins, at a lower temperature than the hydrotreatment, and then passed to the hydrotreatment zone.

    Abstract: The invention concerns a combined process of catalytically hydroreforming a heavy naphtha in at least one reaction zone (10) and catalytically hydroisomerizing a light naptha in at least one reaction zone (34).The invention is characterized in that the hydrogen produced in the hydroreforming unit (line 27) is used to isomerize the light naphtha, the obtained reformate and isomerate being fractionated preferably together in the same stabilization column (51 in FIG. 1).A better thermal integration, a better recovery of light hydrocarbons and a lowering of the utilities requirements and investments, as compared with units operating separately, are thus achieved.
