Embodiment 1

[0027] The raw material oil A used in this example is a mixed raw material of gas oil 1 and residual oil, wherein the residual oil accounts for 15% by weight of the total weight of the raw material. The main properties of the raw material oil A are shown in Table 2. The raw material oil A is mixed with hydrogen and then enters the hydrogenation reactor, where it contacts the hydrogenation protection agent, the residual oil demetallization catalyst and the residual oil desulfurization catalyst in sequence for reaction, and the reaction products are cooled and separated to obtain hydrogen-rich gas and liquid products. Based on the overall catalyst volume, the loading volume percentages of the hydroprotecting agent, the residue hydrodemetallization agent and the residue hydrodesulfurization agent are 5 vol%, 20 vol% and 75 vol%, respectively. The reaction conditions and liquid product properties of the present embodiment are shown in Table 4.

Embodiment 2

[0030] The raw material oil B used in this example is a mixed raw material of gas oil 2 and residual oil, wherein the residual oil accounts for 10% by weight of the total weight of the raw material. The main properties of the raw material oil B are shown in Table 2. The raw material oil B is mixed with hydrogen and then enters the hydrogenation reactor, where it contacts the hydrogenation protection agent, the residual oil demetallization catalyst and the residual oil desulfurization catalyst in turn for reaction, and the reaction products are cooled and separated to obtain hydrogen-rich gas and liquid products. Based on the overall catalyst volume, the loading volume percentages of the hydroprotecting agent, the residual oil hydrodemetallization agent and the residual oil hydrodesulfurization agent are 5 volume%, 45 volume% and 50 volume% respectively. The reaction conditions and liquid product properties of the present embodiment are shown in Table 4.

Abstract

The hydrogenation process for producing catalytically cracked material includes the successive contacting and reaction of the mixture of material oil and hydrogen with hydrogenation protecting agent, residual oil hydrogenating and demetallizing agent and residual oil hydrogenating and desulfurizing agent, cooling the reaction resultants, and separating obtain hydrogen-rich liquid and gas products. The catalyst includes hydrogenation protecting agent in 2-10 vol%, residual oil hydrogenating and demetallizing agent in 5-70 vol%, and residual oil hydrogenating and desulfurizing agent 20-93 vol%. The present invention makes it possible to produce high quality catalytically cracked material via adding residual oil in 5-50 wt% into gas oil.

Description

technical field [0001] The invention belongs to a method for refining hydrocarbon oil in the presence of hydrogen, more specifically, a hydrogenation method for producing catalytic cracking feedstock. Background technique [0002] In recent years, with the rapid development of the national economy, oil consumption has shown a sharp increase, the contradiction between supply and demand is more prominent, the demand for heavy oil is decreasing, and the demand for light oil is increasing. Therefore, in order to make full and reasonable use of oil resources, the oil refining industry must provide Development in the direction of deep processing. In order to improve the depth of crude oil processing and increase the yield of light oil, lightening heavy oil has become one of the main tasks of the refining industry at present and in the future. Catalytic cracking is one of the most important crude oil secondary processing methods, but with the construction of more and more hydrocra...
