Hydroprocessing method and system for low-quality oil
A low-quality oil and hydrogen processing technology, which is applied in the petroleum industry, hydroprocessing process, and hydrocarbon oil treatment, can solve the problems of non-hydroprocessing methods that are difficult to meet the requirements, the yield of refined oil is low, and acid residues are difficult to handle. , to achieve the effect of reduced weight ratio, good quality and short adsorption time

Embodiment 1
[0101] This example follows figure 1 The flow process of the experiment was carried out, and the shale oil in Table 1 was used as inferior oil, and the test was carried out on a small-scale continuous regeneration double-riser reactor. The bottom of the first riser is injected with 40°C gasoline accounting for 22.5% by weight of the shale oil feed as the cooling medium. The lifting medium flows from bottom to top; after the reaction, the denitrified oil gas enters the second riser, and the second riser is transported into the high-temperature thermal regenerant as the second catalytic cracking catalyst; CAT-1 catalyst is used, and the balancer MAT=65. The specific reaction process is as follows: shale oil A enters the bottom of the first riser reactor after being preheated at 260°C, and at a reaction pressure of 4.3 MPa, H 2 The volume ratio of / shale oil is 500, with the hydrogen-containing fluidized medium flowing from bottom to top, the adsorption temperature is 300°C, the...
Embodiment 2
[0110] This example follows figure 1 The flow process of coking gas oil B and vacuum gas oil C in Table 1 are used as raw materials for catalytic cracking, coking gas oil B is used as inferior oil, and the test is carried out on a small-scale continuous regeneration double riser reactor. The first riser faces hydrogen feed, and the first riser introduces a cold regenerant that takes heat from outside as the first catalytic cracking catalyst, with 85% hydrogen as the pre-lift medium flowing from bottom to top; denitrification after reaction Oil gas and vacuum gas oil C as a high-quality catalytic cracking raw material are fed into the second riser, and the second riser is transported into a high-temperature thermal regenerant as the second catalytic cracking catalyst; CAT-1 catalyst is used, and the balancer MAT=65. The specific reaction process is: the coker wax oil B enters the bottom of the first riser reactor after being preheated at 300 ° C, and under the reaction pressure...
