Disclosed herein is a process for efficiently and stably producing high-quality kerosene and gas oil from crude oil or crude oil from which naphtha fraction is removed through the hydrotreatment of the crude oil by using a specific hydrotreatment catalyst; a process capable of prolonging the service life of the catalyst; a process capable of extending the continuous operation period of the process equipment; a process simplifying a petroleum refinery equipment; and the like. There are used, as hydrotreatment catalysts in the hydrotreatment of a hydrocarbon oil, the metals each belonging to any of the groups 6, 8, 9 and 10 of the Periodic Table which metals are supported on a carrier composed of alumina/boria, metal-containing aluminosilicate, alumina/an alkaline earth metal compound, alumina/phosphorus, alumina/titania or alumina/zirconia.

Process for hydrotreating hydrocarbon oil

An apparatus for evaluating a solid catalyst which can enlarge a range of an applied fluid used for an evaluation of a performance of the solid catalyst and can accurately evaluate the performance of the solid catalyst on a laboratory scale and a method of evaluating a solid catalyst using the apparatus are provided. There are disclosed an apparatus of evaluating a solid catalyst, wherein a raw material feeding portion has a function capable of continuously feeding a liquid raw material or a mixed raw material consisting of a gas and a liquid, wherein a reactor in a reacting portion has an inlet for a fluid raw material and reaction product outlets for discharging a reaction product while separating it into a liquid product and a gaseous product, and wherein a recovering portion has reaction product inlets connected to each of the reaction product outlets of the reactor and has a liquid level control portion for keeping a liquid level within the reactor constant, and a method of evaluating a solid catalyst using the apparatus.
