|Title:||METHOD FOR STARTUP OF BUBBLE TOWER-TYPE SLURRY BED REACTOR|
Provided is a method for the startup of a bubble tower-type slurry bed reactor for producing hydrocarbons by Fischer-Tropsch synthesis. The method comprises a first step for filling in a reactor a slurry obtained by suspending a Fisher-Tropsch synthesis catalyst in an oil for preparing a slurry having a 5% distillation temperature between 120 and 270ºC, a 95% distillation temperature between 330 and 650ºC, and a sulfur content and aromatic content of 1 ppm or less in terms of mass, and a second step for initiating Fischer-Tropsch synthesis by raising the temperature of the reactor, with synthetic gas that is primarily hydrogen and carbon monoxide already being introduced to the slurry filled in the reactor. The oil for slurry preparation is an oil that contains a predetermined amount of specific components. During the first step, the slurry is filled into the reactor in an amount such that none sprays out from the reactor.
