Embodiment 1

[0018] The crude oils processed in Example 1 and Example 2 are different. After these two different crude oils are treated by the purification device, they enter the atmospheric and vacuum device to obtain light distillate oil, the vacuum wax oil fraction at 350-470°C and the vacuum wax oil fraction at 470°C+ Vacuum heavy oil fraction.

[0019] where 470°C + The vacuum heavy oil fraction is heated to 520°C and enters the coke tower, and after coking reaction, the products and their properties listed in the following table are obtained.

[0020] Example 1

[0021] Embodiment 1 is the vacuum wax oil+350 ℃ of 30wt% crude oil + Catalytic cracking tail oil + coker wax oil enters the hydrocracking unit and is controlled at 350°C + Distillation is converted into 350 DEG C fraction conversion rate is 60wt%; Embodiment 2 is the vacuum gas oil+350 DEG C of 20wt% crude oil + Catalytic cracking tail oil + coker wax oil enters the hydrocracking unit and is controlled at 350°...

Abstract

The process of producing clean fuel with petroleum hydrocarbons has well combined hydrocracking process, hydrodesulfurizing process, catalytically cracking process and coking process. It has most of decompressed wax oil from crude oil desulfurized and catalytically cracked, the coked wax oil obtained through coking catalytically cracked tail oil and vacuum residual oil hydrocracked, and the hydrocracked tail oil catalytically cracked for the second time. The combined process can obtain petroleum coke product, high quality hydrocracked light oil product and catalytically cracked light oil product simultaneously. Facilitate the operation of hydrocracking apparatus, increase the service life of the catalyst and obtain clean fuel in high economic benefit.

Description

technical field [0001] The invention relates to a processing method for producing clean fuel from petroleum hydrocarbons, in particular to a new process combining coking technology, hydrodesulfurization technology, hydrocracking technology and catalytic cracking technology. Background technique [0002] With the worldwide economic development and increasingly stringent environmental regulations, there are stricter requirements on the demand and quality of petroleum products. At the same time, crude oil worldwide is getting heavier and worse, which brings more difficulties to processing. [0003] The existing crude oil processing process is generally as follows: the light oil product from the atmospheric and vacuum unit is directly mixed with the light oil product obtained from other devices (or after being refined) and directly leaves the factory, and the vacuum wax oil enters the hydrocracking unit to obtain high-quality Light oil products and high-quality tail oils, as de...
