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.

Combined hydroreforming-hydroisomerization process

Apparatus and continuous process for converting hydrocarbons in the presence of a granular catalyst including a metal from group VI a, VII a or VIII, deposited on a carrier, comprising passing a charge of hydrocarbons with hydrogen through a series of at least two vertical catalytic zones in which the catalyst bed moves progressively downwardly, withdrawing progressively the catalyst from the bottom of the last catalytic zone, and reintroducing the same, after regeneration, at the top of the first catalytic zone.
