Embodiment 1
[0084] This embodiment follows the attached image 3 MGCO-2 was used as the catalyst, and the feedstock oil A was directly used as the easily cracked feedstock oil for catalytic cracking. The test was carried out on the medium-sized device from the riser reactor. The easily cracked feedstock oil entered the middle and upper part of the reaction zone I. The cracked feedstock oil enters the bottom of the reaction zone I. At the bottom of reaction zone I, the refractory feedstock oil is at a reaction temperature of 600℃ and a weight hourly space velocity of 240h -1 , The weight ratio of catalytic cracking catalyst to difficult-to-crack feedstock oil is 30, and the weight ratio of steam to difficult-to-crack feedstock oil is 0.20. Time and space speed 90h -1 , The weight ratio of the catalytic cracking catalyst to the easily cracked feed oil is 10, and the weight ratio of steam to the easily cracked feed oil is 0.15 for the cracking reaction. In the reaction zone II, the reactant f...
Embodiment 2
[0090] This embodiment follows the attached Figure 4 MGCO-2 was used as the catalyst, and the feed oil B was directly used as the refractory feed oil for catalytic cracking. The test was carried out on a medium-sized device from the riser reactor. The refractory feed oil enters the bottom of the reaction zone I to react. The cracked feedstock oil enters the middle and upper part of reaction zone I for reaction. At the bottom of the reaction zone I, the refractory feedstock oil has a reaction temperature of 580℃ and a weight hourly space velocity of 200h -1 , The weight ratio of the catalytic cracking catalyst to the refractory feed oil is 60, and the weight ratio of steam to the refractory feed oil is 0.20. The cracking reaction is carried out; in the upper middle and upper part of the reaction zone I, the easily cracked feed oil is at a reaction temperature of 550℃ and heavy Time and space speed 120h -1 , The weight ratio of catalytic cracking catalyst to easily cracked feed ...
