Claim:
1. A process for producing fuel hydrocarbon components, said process comprising: providing a terpene feed selected from a group consisting of crude sulphate turpentine derived from kraft pulping process of wood (CST), crude turpentine derived from mechanical pulping of wood, distillation bottoms from turpentine distillation, turpentine evaporated from crude tall oil, sulphur-containing C5 to C10 hydrocarbon streams from wood processing, and mixtures thereof, at a WHSV of about 0.5 to about 10, measured in accordance with the following equation: wherein V feed[g/h] means a pumping velocity of the terpene feed, and M catalyst[g] means an amount of the catalyst; subjecting the terpene feed and a hydrogen gas, in a volumetric ratio of hydrogen gas to the terpene feed of from about 100 to about 1500 Nl/l, to a hydrogenation step at a temperature range of from about 275° C. to about 425° C. and at a pressure of 10 to 150 bar, in the presence of a hydrodesulphurization catalyst selected from a group consisting of NiO/MoO recycling at least a portion of the hydrocarbon components back to the terpene feed and/or to the hydrogenation step.
