Embodiment a
[0067] The present embodiment provides a kind of processing method of catalytic cracking oil slurry, and this method comprises:
[0068] 1) Add a peroxide crosslinking agent (dicumyl peroxide) to the catalytic cracking oil slurry (the oil slurry thrown out of the catalytic cracking unit), and the addition amount is 0.01% of the mass of the catalytic cracking oil slurry to form a mixed material;
[0069] 2) Use a tubular heating furnace to preheat the mixed material (50°C), and then heat it to 380°C;
[0070] 3) Pass the heated mixed material into the upper part of the reactor (empty cylinder reactor) to allow it to stay for staged cracking reaction. The staged cracking reaction was carried out at a reaction temperature of 460°C.
[0071] 4) The staged cracking reaction oil gas is discharged from the top of the reactor and then enters the fractionation tower to fractionate gas, gasoline, diesel oil and wax oil; the staged cracking reaction extracts the oil from the bottom of t...
Embodiment b
[0073] The present embodiment provides a kind of processing method of catalytic cracking oil slurry, and this method comprises:
[0074] 1) Add a peroxide crosslinking agent (dicumyl hydrogen peroxide) to the catalytic cracking oil slurry (the oil slurry thrown out of the catalytic cracking unit), and the addition amount is 0.09% of the mass of the catalytic cracking oil slurry to form a mixed material;
[0075] 2) Use a tubular heating furnace to preheat the mixed material (90°C), and then heat it to 420°C;
[0076] 3) Pass the heated mixed material into the upper part of the reactor (visbreaking reactor) to allow it to stay for staged cracking reaction. , and at a reaction temperature of 490° C., the staged cracking reaction is carried out.
[0077] 4) The staged cracking reaction oil gas is discharged from the top of the reactor and then enters the fractionation tower to fractionate gas, gasoline, diesel oil and wax oil; the staged cracking reaction extracts the oil from t...
Embodiment c
[0079] The present embodiment provides a kind of processing method of catalytic cracking oil slurry, and this method comprises:
[0080] 1) Add a peroxide crosslinking agent (benzoyl peroxide) in the catalytic cracking oil slurry (the oil slurry thrown out of the catalytic cracking unit), and the addition amount is 0.04% of the mass of the catalytic cracking oil slurry to form a mixed material;
[0081] 2) Use a tubular heating furnace to preheat the mixed material (65°C), and then heat it to 390°C;
[0082] 3) Pass the heated mixed material into the upper part of the reactor (circulatory bed reactor) to allow it to stay for staged cracking reaction. The staged cracking reaction was carried out at a reaction temperature of 470°C.
[0083] 4) The staged cracking reaction oil gas is discharged from the top of the reactor and then enters the fractionation tower to fractionate gas, gasoline, diesel oil and wax oil; the staged cracking reaction extracts the oil from the bottom of ...
