摘要： A process for starting up a Fischer-Tropsch reactor includes establishing, in the reactor, an initial charge of molten wax. The initial reactor temperature is below the line-out reactor temperature but is sufficiently high for a Fischer-Tropsch reaction to take place. The reactor contains, in contact with the molten wax, at least a portion of its line-out catalyst inventory. Syngas is fed into the reactor at an initial flow rate below the line-out syngas flow rate. Initially a syngas H2:CO molar ratio is maintained at a higher value than its line-out value, whereafter the syngas H2:CO molar ratio is decreased to its line-out value. The syngas flow rate and the reactor temperature are then increased to their line-out values.
