Abstract (en)
[origin: EP0832958A1] A new process for the production of petrol with a low sulphur content from a crude product obtained from catalytic cracking units containing olefins, mercaptans and S compounds other than mercaptans, in which: (1) the crude petrol is fractionated into a light cut, with a b.pt. less than or equal to 210 degrees C.containing most of the olefins, and a heavy fraction; (2) the light cut is subjected to a moderate hydrotreatment in the presence of H2 with a catalyst containing a group VIII metal and/or a group VI metal, at 160 - 380 degrees C. and 5 - 50 bars, and the effluent is stripped to eliminate H2S; (3) the light fraction is also submitted to a sweetening process effected either by: a treatment before the moderate hydrotreatment, in the presence of H2 with a supported catalyst containing 0.1 - 1% Pd at 4 - 50 bars; an extractive sweetening of the effluent after hydrotreatment and stripping ; or - sweetening with an oxidant, a catalyst and alkaline base(optionally incorporated with the catalyst) of the effluent after hydrotreatment. Also claimed, is the installation for effecting the process.
