ABSTRACT:
In the purification of a hydrogen stream contaminated with at least methane and ethane, e.g. a hydrogen cycle gas from a coal hydrogenation process, where the hydrogen stream is subjected to multistage partial condensation and separation of the respectively formed condensates, the improvement of subjecting the hydrogen stream under a pressure of above about 100 bar to the multistage partial condensation and separation of having in the final condensate 5-40 molar percent of ethane, thereby favorably altering the K-value of methane and its ease of removal from the hydrogen which is only altered in the manner desired when the process is conducted under pressures in excess of about 100 bar.
