Method for starting up bubble-column-type slurry-bed reactor, start-up solvent, and method for producing hydrocarbon oil

摘要

This method for starting up a bubble-column-type slurry-bed reactor is characterized in that, at the time of re-starting a bubble-column-type slurry-bed reactor for producing hydrocarbons by the Fischer-Tropsch synthesis reaction, a hydrotreated oil that has been produced in the bubble-column-type slurry-bed reactor and hydrotreated is supplied to the bubble-column-type slurry-bed reactor, the hydrotreated oil having a peroxide value of 1 ppm or less and containing 40% by mass or more of paraffin hydrocarbons with carbon numbers of 21 or greater.
