Method for producing hydrocarbons with catalyst conditioning

摘要

Continuous production of hydrocarbon from synthesis gas involves reacting synthesis gas in presence of catalyst in Fischer-Tropsch synthesis reactor (4) by conditioning catalyst in reduced state in a conditioning reactor (2) by contact with a flow of reducing gas from a synthesis gas source supplying the synthesis reactor, and reducing conditioning gas comprising carbon monoxide or mixture comprising hydrogen and carbon monoxide. Continuous production of hydrocarbon from synthesis gas involves reacting synthesis gas in presence of catalyst in Fischer-Tropsch synthesis reactor (1) by conditioning catalyst in reduced state in a conditioning reactor (2) by contact with a flow of reducing gas from a synthesis gas source supplying the synthesis reactor, and reducing conditioning gas comprising carbon monoxide or mixture comprising hydrogen and carbon monoxide at 200-500[deg] C under total pressure of 0.1-5 MPa with gas flow of 1-20 NI/hour/g of to-be-treated catalyst for 1-48 hour. The molar ratio of hydrogen to carbon monoxide is 0.01-0.9.
