Abstract (en)
[origin: FR2771417A1] Isomerization of C5-C8 paraffin fractions rich in paraffins with more than 7 C atoms is carried out by treating the feed in a reaction zone comprising of a supported catalyst containing at least a halogen and a metal of group VIII, in fix bed, the reaction being carried out between 30-150 deg.C. The totality of the effluent of the first hydroisomerization section passes through the second section. The separation section is based after the hydroisomerization sections, the feed is mixed with the recycled linear paraffins from the separation section and the resulting mix is sent to the first hydroisomerization section. The effluent from the first hydroisomerization section is mixed with the flux rich in mono-branched paraffins from the separation section which is then sent to the second hydroisomerization section and the effluent from that section is then sent to the separation section. The separation section is also located before the hydroisomerization sections, the feed is mixed with the flux resulting from the second hydroisomerization section and the resulting mixture is sent to separation section. The effluent rich in linear paraffins section is sent to the first hydroisomerization section and the flux rich in mono-branched paraffins from the separation section is added to the effluent from the first hydroisomerization section and the resulting mixture is sent to the second hydroisomerization section.
