ABSTRACT:
Hydrocarbons are prepared from a feed gas of hydrogen and carbon monoxide by feeding the feed gas into a reaction zone at an elevated temperature and pressure and allowing the hydrogen and carbon monoxide to react in the presence of a catalyst retained in the reaction zone to yield hydrocarbons. A reservoir of a hydrogen-rich gas is maintained at a pressure above the pressure of the feed gas, the reservoir and the reaction zone being connected in such a way that a continuous flow of hydrogen-rich gas is maintained from the reservoir into the reaction zone. A reactor in use in the preparation is shutdown by interrupting the feeding of the feed gas, thereby allowing hydrogen-rich gas to flow from the reservoir at increased rate and quench the reactions occurring in the reaction zone.
