Abstract:
A method for starting up a bubble column slurry bed reactor of the present invention includes, when restarting operation of a bubble column slurry bed reactor for producing hydrocarbons by the Fischer-Tropsch synthesis reaction, feeding a hydroprocessed oil produced in the bubble column slurry bed reactor and hydroprocessed that contains 40% by mass or more of paraffin hydrocarbons having carbon number of 21 or more and that has a peroxide value of 1 ppm or less, to the bubble column slurry bed reactor.
