    摘要: The present invention provides a process for the conversion of a paraffinic feedstock that comprises at least 50 wt % of compounds boiling above 370° C. and which has a paraffin content of at least 60 wt %, an aromatics content of below 1 wt %, a naphthenic content below 2 wt % a nitrogen content of below 0.1 wt %, and a sulphur content of below 0.1 wt %, which process comprises the steps of: (a) providing the feedstock to a reaction zone, where it is contacted with hydrogen at a temperature in the range of 175 to 400° C. and a pressure in the range of 20 to 100 bar in the presence of a catalyst comprising 0.005 to 5.0 wt % of a Group 8 noble metal on a carrier, the carrier comprising 0.1-15 wt % of a zeolite beta and at least 40 wt % of an amorphous silica-alumina, calculated on the weight of the catalyst, said zeolite beta having a silica:alumina molar ratio of at least 50, and said amorphous silica-alumina having an alumina content, calculated as Al2O3, of 5-70 wt %; (b) withdrawing the effluent from the reaction zone through an outlet; (c) subjecting the effluent from the reaction zone to a fractionation step to form at least a heavy fraction, an intermediate fraction, and a light fraction; and (d) providing at least part of the heavy fraction to the inlet of the reaction zone.
