Problems solved by technology

[0010] Whether it is US6428686 or CN200810049938.7, the reactor outlet stream is directly recycled to the reactor inlet or between the catalyst beds, although CN200810049938.7 uses the liquid phase coming out of the separator as circulating oil, and the liquid phase coming out of the separator The hydrogen sulfide phase contains dissolved hydrogen sulfide, which is produced by removing sulfide from the raw material during the hydrogenation reaction. This is the desired reaction for the hydrogenation reaction, but the hydrogen sulfide in the cycle oil will affect the activity of the catalyst. Inhib

Abstract

The invention discloses a hydrocarbon oil hydrogenation reactor, which comprises a reactor barrel body and a catalyst bed layer. An outlet and an inlet are respectively formed at the upper part and lower part of the reactor. The reactor is characterized in that: at least one mixer is arranged in the reactor; the reactor is provided with a raw material mixture and a hydrogen inlet and also a hydrogen-containing mixture and a gas outlet; and the inlet of the mixer is connected with the inlet of reactor. Due to the adoption of the reactor, pressure difference of the pressure in the mixer and the pressure outside the mixture is reduced, wall thickness of the reactor is thinned, and equipment investment and operating cost are decreased.

Description

technical field [0001] The invention relates to the technical field of hydrocarbon oil processing in the presence of hydrogen, in particular to a liquid-phase hydrogenation method for hydrocarbon oil. Background technique [0002] In hydrocarbon oil processing technology, hydrogenation technology is one of the commonly used technologies to improve the quality of hydrocarbon oil. As the global crude oil market tends to supply crude oil with higher sulfur content, refineries need to process low-quality hydrocarbon oil with higher sulfur content. Impurities such as sulfur, nitrogen, oxygen and metals are removed during the refining process, and the quality of hydrocarbon oil is changed by changing the molecular structure, so that various products meet the specification requirements. The hydrogen that participates in the reaction in the hydrocarbon oil hydrogenation process is actually only hydrogen used for chemical hydrogen consumption, while the traditional trickle bed reacto...
