Embodiment 1
[0040] Example 1: A certain 100×10 4 The t / a catalytic cracking unit is regenerated with compressed air at 200°C. Such as Figure 4 and figure 1 As shown, the carbon content of the regenerated agent 10 is 1.3%, the temperature is 490° C., the carbon content of the outgoing regenerated agent 23 is 0.05%, and the oxygen content in the flue gas 27 at the outlet of the regenerator is about 1%. The distribution plate 15, 18 through-hole flow rate is 15-20m / s, and the amount of catalyst returned through the return pipe 19 is 2.5 times of the circulation volume of the spent agent, and 1.5 times of it enters the first-stage regenerator from the distribution plate 15 to increase the first-stage regeneration temperature. The catalyst in the second stage regenerator enters the third stage after being cooled by the external heat collector 50, and 51 is a slide valve.
[0041] The regeneration temperature, air intake volume, superficial gas flow velocity, char ratio and device height da...
Embodiment 2
[0048] Embodiment 2: device structure such as figure 2 As shown, the gas superficial flow velocity of each section is 1.2m / s for the first section, 0.8m / s for the second section, and 0.8m / s for the third section; 8m high. The amount of catalyst returned through the return pipe 33 is 1.2 times of the amount to be generated, and the amount of catalyst returned through the catalyst return pipe 35 is 1.5 times of the amount to be generated. Other processing parameters are as embodiment 1.
Embodiment 3
[0049] Embodiment 3: device structure such as image 3 As shown, the catalyst entering the third section through the catalyst return pipe 39 is 1.0-2.0 times of the amount to be produced. Others are the same as embodiment 2.
