Embodiment 1
[0059] This embodiment is implemented according to the accompanying drawings, the vacuum residue oil A is used as the raw material of catalytic cracking, and is tested on the medium-sized device of the riser reactor, and the inferior raw material enters the lower part of the reaction zone I, contacts with the catalyst GZ-1 and occurs Reaction, in the lower part of reaction zone I, inferior raw material is at reaction temperature 595 ℃, weight hourly space velocity 100h -1 , the weight ratio of catalyst to raw material is 6, and the weight ratio of steam to raw material is 0.05 to carry out the cracking reaction; in reaction zone II, the oil and gas are at a reaction temperature of 500 °C and a weight hourly space velocity of 30 h. -1 , under the condition that the weight ratio of steam to raw material is 0.05, the cracking reaction is carried out, the oil and gas and the catalyst with carbon are separated in the settler, and the product is cut according to the distillation rang...
Embodiment 2
[0065] This embodiment is tested according to the flow chart of the accompanying drawing. The high-acid crude oil raw material B is used as the raw material for catalytic cracking, and the test is carried out on the medium-sized device of the riser reactor. The inferior raw material enters the lower part of the reaction zone I, contacts with the catalyst GZ-1 and generates A reaction occurs, and in the lower part of the reaction zone I, the inferior raw materials have a reaction temperature of 595 ° C and a weight hourly space velocity of 100 h. -1 , the weight ratio of catalyst to raw material is 6, and the weight ratio of steam to raw material is 0.05 to carry out the cracking reaction; in reaction zone II, the oil and gas are at a reaction temperature of 500 °C and a weight hourly space velocity of 30 h. -1 , the cracking reaction is carried out under the condition that the weight ratio of steam to raw material is 0.05, the oil and gas and the catalyst with carbon are separa...
