METHOD FOR STARTING UP NAPHTHA FRACTION HYDROTREATING REACTOR

摘要

A method for starting-up a naphtha fraction hydrotreating reactor which subjects a naphtha fraction obtained in a fractionator by fractional distillation of hydrocarbon compounds produced by a Fischer-Tropsch synthesis reaction to hydrotreating, the method comprising: charging in advance an inactive hydrocarbon compound corresponding to the naphtha fraction into a vapor-liquid separator to which hydrogenated naphtha, which has been subjected to hydrotreating in the naphtha fraction hydrotreating reactor, is transferred; mixing the inactive hydrocarbon compound drawn from the vapor-liquid separator and the naphtha fractions being transferred from the fractionator to the naphtha fraction hydrotreating reactor, and supplying a mixture of the naphtha fractions and the inactive hydrocarbon compound to the naphtha fraction hydrotreating reactor.
