Embodiment

[0033] In this embodiment, a kind of heavy distillate oil is used as feedstock oil, and its raw material properties are shown in Table 1. From Table 1, it can be seen that the sulfur content of this feedstock oil is as high as 3.1% by weight, which is an inferior high-sulfur heavy distillate oil. According to the method provided by the present invention, the feedstock oil is processed, and products such as naphtha fraction, gasoline fraction and diesel fraction are obtained after successively passing through a hydrogenation unit and a catalytic cracking unit. The operating conditions of the hydrogenation unit are as shown in Table 2, and the operating conditions of the catalytic cracking unit are as shown in Table 3. As can be seen from Table 2 and Table 3, the relatively mild reaction conditions that are adopted in this embodiment, wherein the hydrogenation The reaction pressure of the unit is only 10.0MPa. The yield of each fraction is shown in Table 4, and the properties of...

Abstract

Production of clean fuel by heavy-fraction oil is carried out by hydrogenation refining for heavy-fraction oil, separating to obtain heavy material and light material, delivering heavy material to catalytic unit to be treated, and entering light material and light circulation oil of catalytic unit into reactor to hydrogenation upgrade. It's cheap, has shorter process flow path and better quality. The final products include diesel fraction, gasoline fraction and naphtha fraction to be used as catalytic reforming raw material.

Description

technical field [0001] The present invention pertains to a method of treating hydrocarbon oils with at least one hydrotreating process and at least one other conversion step. More specifically, it is a method for producing clean fuels from heavy distillates through hydrogenation units and catalytic cracking units. Background technique [0002] Out of the needs of environmental protection, countries around the world have formulated more stringent fuel specifications, requiring refineries to produce environmentally friendly gasoline and diesel products with good performance and low emissions of toxic and harmful substances. my country's quality requirements for gasoline and diesel are also becoming increasingly stringent, and the standards are formulated with reference to the "European Emission Standards". Currently, the standards implemented nationwide are Euro I, while the gasoline and diesel standards implemented in the three major cities of Beijing, Shanghai and Guangzhou...
