Process for the production of liquid hydrocarbons

摘要

Process for producing normally liquid hydrocarbons from a hydrocarbonaceous feed which process comprises the following steps: (i) partial oxidation of the hydrocarbonaceous feed at elevated temperature and pressure using a pressurized oxygen containing gas to obtain synthesis gas; (ii) quenching and/or cooling the synthesis gas obtained in step (i) with water obtained in step (iii) as described below; (iii) catalytically converting at least part of the synthesis gas mixture obtained in step (ii) at elevated temperature and pressure into normally liquid hydrocarbons, normally gaseous hydrocarbons and water; (iv) expanding and/or combusting at least part of the normally gaseous hydrocarbons to provide power for compressing and optionally separating the oxygen containing gas used in step (i), and (v) optionally introducing the process water obtained in step (iii) after use as cooling medium in step (ii) in the expanding/combustion process of step (iv).
