Embodiment 1

[0036] use figure 1 In the combined process flow shown, catalytic diesel is selected as the raw material of inferior diesel. The catalysts used in the examples are commercial catalysts FF-36 hydrotreating catalyst and 3963 hydrogenation upgrading catalyst developed by Sinopec Fushun Petrochemical Research Institute and produced by Sinopec Catalyst Corporation Fushun Branch. The loading ratio of the catalyst is 45v%:55v%.

[0037] The properties of raw oil are shown in Table 1, and the operating conditions are shown in Table 2.

Embodiment 2

[0039] use figure 1 In the combined process flow shown, coking diesel oil is selected as the raw material of inferior diesel oil. The catalyst used in the embodiment is the same as in Example 1.

Abstract

The invention discloses a hydrogenation combination process for producing high-quality white oil. The process comprises the following steps: (1) mixing a poor diesel raw material with hydrogen under the hydro-upgrading process condition, and enabling a mixture to pass through a hydro-upgrading reaction region with a hydro-upgrading catalyst bed layer; (2) feeding a reaction effluent obtained in the step (1) into a hydro-refining reaction region for hydro-refining; (3) performing gas-liquid separation on a reaction effluent obtained in the step (2), and feeding an obtained liquid product into an aromatic extraction device for aromatic separation to obtain an aromatic component and a non-aromatic raffinate oil component, wherein the aromatic component can enter a catalytic cracking unit or a BTX aromatic unit, and the non-aromatic raffinate oil component is the high-quality white oil. The non-aromatic raffinate oil obtained by the process is the high-quality white oil which is sulfur-free and aromatic-free and has the pour point of lower than 0 DEG C and the Saybolt color value of more than +20; due to the adoption of the process, the poor diesel can be converted into a high-added-value white oil product to the maximum extent, the application range of the poor diesel is extended, and the economic benefit of the processed poor diesel is increased.

Description

technical field [0001] The invention relates to a hydrogenation method for producing white oil fractions, in particular to a combined hydrogenation process for processing inferior diesel oil to obtain high-quality white oil fractions. Background technique [0002] Catalytic cracking is currently the most important secondary processing process in the petroleum refining industry, and it is also the core process of lightening heavy oil. As the world's oil becomes increasingly heavy, the processing capacity of the FCC unit is also continuously improved. Using various heavy oils as raw materials, high-octane gasoline, the main product, is obtained through catalytic cracking reactions, and a large amount of sulfur, nitrogen, and aromatics are produced at the same time. Catalytic diesel oil with high content, low cetane number or cetane index, and extremely poor stability. Moreover, the requirements of environmental protection regulations are becoming more and more stringent, and ...
