Abstract
The disclosed invention relates to a method for restarting a synthesis gas conversion process which has stopped. The synthesis gas conversion process may be conducted in a conventional reactor or a microchannel reactor. The synthesis gas conversion process may comprise a process for converting synthesis gas to methane, methanol or dimethyl ether. The synthesis gas conversion process may be a Fischer-Tropsch process.
Claims55
A method for restarting a synthesis gas conversion process, wherein the synthesis gas conversion process comprises flowing synthesis gas into a reactor in contact with a synthesis gas conversion catalyst at a desired reaction temperature and pressure to produce a synthesis gas conversion product and flowing effluent comprising the synthesis gas conversion product out of the reactor, the method comprising:
- (A) stopping the flow of synthesis gas into the reactor;
- (B) flowing natural gas into the reactor to purge the reactor;
- and
- (C) restarting the flow of synthesis gas into the reactor;
- wherein the reactor comprises a microchannel reactor.
