Title: HYDROCARBON SYNTHESIS USING REACTOR TAIL GAS FOR CATALYST REJUVENATION
Abstract:
Hydrogen containing tail gas from a hydrocarbon synthesis reactor is used as a hydrogen containing catalyst rejuvenating gas. If CO is present, the CO content is less than 10 mole % of the gas and the H2 to CO mole ratio is greater than 3:1. At least a portion of the water and liquid hydrocarbons are removed from the tail gas, before it is used to rejuvenate the reversibly deactivated catalyst.
