Abstract
The invention deals with a method for preparing a nitrogen-depleted hydrocarbon feedstock (315, 412, 514, 614, 714, 718, 814, 822) having (i) an initial boiling point comprised between 0° C. and +180° C. and a final boiling point comprised between 30° C. and 250° C., and (ii) an olefin content higher than 5 weight %, by contacting a hydrocarbon feedstock starting material (310, 313, 410, 411, 510, 512, 610, 612, 710, 712, 713, 810, 812, 813) with a clay sorbent material in a reaction vessel (33,43,53,63,73,73,83,83), wherein the nitrogen-depleted hydrocarbon feedstock (315, 412, 514, 614, 714, 718, 814, 822) has a total nitrogen/nitrile ratio (ppm/ppm) comprised between 1 and 5. Additional purification section allows improved units working time and lower maintenance.
