METHOD FOR STARTING UP BUBBLE-COLUMN-TYPE SLURRY-BED REACTOR, START-UP SOLVENT, AND METHOD FOR PRODUCING HYDROCARBON OIL

摘要

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 FISCHERA-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.
