Abstract

See full text

A process for hydrotreating a naphtha fraction that includes a step of estimating the difference between the naphtha fraction hydrotreating reactor outlet temperature and inlet temperature, based on the reaction temperature of the Fischer-Tropsch synthesis reaction and the ratio of the flow rate of the treated naphtha fraction returned to the naphtha fraction hydrotreating step relative to the flow rate of the treated naphtha fraction discharged from the naphtha fraction hydrotreating step, a step of measuring the difference between the naphtha fraction hydrotreating reactor outlet temperature and inlet temperature, and a step of adjusting the reaction temperature of the naphtha fraction hydrotreating step so that the measured difference between the naphtha fraction hydrotreating reactor outlet temperature and inlet temperature becomes substantially equal to the estimated difference between the naphtha fraction hydrotreating reactor outlet temperature and inlet temperature.
