PROCESS FOR THE HYDROTREATING OF A HEAVY OIL

摘要

A process for the hydrotreating of a heavy oil by leading the heavy oil and hydrogen at elevated temperature and pressure concurrently in downward direction through a reactor which contains at least one bed of a solid catalyst, in which process also a hydrocarbon mixture, which is at least for the greater part in the gaseous phase at the conditions prevailing in the reactor, is introduced into the reactor at a point upstream of the uppermost bed of solid catalyst.
