Abstract

The invention provides a device for lightening heavy oil by the aid of suspension-bed hydrogenation technologies. The device comprises a raw oil pretreatment unit, a catalyst slurry preparation unit,a suspension-bed hydrogenation unit, a separation unit and a fixed-bed hydrogenation unit. The raw oil pretreatment unit, the catalyst slurry preparation unit, the suspension-bed hydrogenation unit, the separation unit and the fixed-bed hydrogenation unit are sequentially connected with one another. The device has the advantages that raw oil is pretreated, accordingly, coking of the raw oil in hydrogenation procedures can be prevented, and the device is favorable for increasing the raw oil conversion rate and the light oil yield; slurry is preliminarily prepared from catalysts, accordingly, the catalysts and the raw oil can be mixed with one another in a high-dispersion manner, and the catalysts can be promoted to effectively realize effects; the device is provided with suspension-bed reactors with liquid-phase self-circulation or cold wall functions, accordingly, coking can be reduced and even can be prevented, and coke discharge can be facilitated; light components and heavy components in suspension-bed hydrogenation products are separated in advance, fixed-bed hydrogenation is only carried out on medium components, accordingly, fixed-bed hydrogenation load can be relieved to a great extent, the service lives of fixed-bed catalysts can be prolonged, more importantly, the yields of gasoline and diesel can be increased, the quality of the gasoline and the diesel can be improved, and the device is favorable for energy conservation and emission reduction of integral systems.

Description

technical field [0001] The invention relates to the technical field of coal and petrochemical industry, in particular to a device for realizing the lightening of heavy oil by utilizing the suspension bed hydrogenation technology. Background technique [0002] In recent years, with the increasing shortage of petroleum resources in the world, the trend of heavy and inferior crude oil becoming more and more serious, the rapid decrease in market demand for heavy fuel oil and the continuous and rapid growth of demand for light fuel oil, the heavy and inferior Oil deep processing technology has become the focus and difficulty in the development of oil refining industry. In addition, my country's basic national conditions of poor oil and rich coal, and some petrochemical products can also be obtained from coal gasification, dry distillation and other products, so the use of advanced coal conversion technology to produce gasoline, diesel and chemical products is not only beneficial ...
