Problems solved by technology

However, the reaction pressure of this technology is 30PMa, which makes industrial production difficult, and the oil yield is less than 60%.
[0005] Patent No. CN103773483A discloses a fluidized bed hydrogenation process for increasing the yield of coal liquefied oil and light oil. The process is to first cut the FCC oil slurry into light fraction and heavy fraction, and then hydrogenate the heavy fraction and then combine with coal liquefied oil. Mixed into fluidized bed hydrotreating, the feature of this process is to increase the light oil yield of the unit, but the energy consumption of the unit is increased, and the requirements for raw materials are strict

Description

technical field [0001] The invention belongs to the technical field of coal direct liquefaction, and relates to a kerosene co-refining technology, in particular to a method for co-refining oil by using FCC oil slurry and coal. Background technique [0002] With the improvement of industrial production and daily life, my country's demand for oil is also increasing rapidly. For a long period of time in the future, the main energy consumption in my country will still be coal. Due to energy structure problems, serious smog, water pollution Environmental problems such as pollution, so strengthening the comprehensive utilization of coal resources is still the main problem we have to face. The development of new coal chemical industry is of great significance to alleviate the dependence on foreign oil, reduce environmental hazards, and improve the comprehensive utilization rate of energy. Shaanxi Yanchang Petroleum (Group) has abundant and high-quality coal resources, and can produ...
