A 65 wt % yield of hexane‐soluble liquid, containing 83% of the feed carbon, was obtained when Finnish Carex‐peat pyrolysate was hydrotreated batchwise (21.5 MPa for two hours at 390°C with 10 wt % catalyst, 4% CoO/15.5% MoO 3 on γ‐alumina). Oxygen content was lowered from 22% to 3% in the process. Nitrogen and sulphur contents of the product were 4.3% and 0.10%, respectively. Straight‐chain material predominated in the upgraded product and C 14 ‐C 29 n‐alkanes have been identified along with some phenols. The peat pyrolysate is also predominantly straight‐chain material, but contains polar functionalities such as the carboxyl group.
