摘要:
在小型提升管中试装置上,通过催化裂化反应-再生循环试验,考察了富氧燃烧再生应用于催化裂化装置的可行性,并从催化剂孔结构和酸性角度揭示了再生气体组成对反应规律的影响。结果表明:催化裂化再生过程采用富氧燃烧再生代替常规空气再生,在烧焦效果和裂化反应方面均可行,不会对反应产物和装置平稳运行产生不良影响;富氧燃烧再生过程需要关注高浓度CO2气氛对再生床层温度的影响;相同氧浓度条件下,富氧燃烧再生效果与空气再生效果一致,并且氧浓度与再生效果、反应转化率呈正相关;通过调节再生气体组成,可以灵活调节再生器的烧焦效率、烧焦负荷以及加工能力,提高装置的整体经济性;富氧燃烧再生技术既能提高装置操作灵活性,又能实现催化裂化装置的CO2捕集。
Abstract:
On a small-scale riser pilot plant, the feasibility of the fluid catalytic cracking(FCC) oxy-fuel combustion regeneration was investigated through the FCC reaction-regeneration cycle test, and the effects of different regeneration gas compositions on the reaction law were revealed from the perspective of catalyst pore structure and acidity. The results showed that using oxy-fuel combustion regeneration instead of conventional air regeneration in the FCC regeneration process was feasible in terms of coke burning effect and cracking reaction. It would not have adverse effects on the reaction products and the smooth operation of the plant. The regeneration process of oxy-fuel combustion required attention to the influence of high concentration CO2 atmosphere on the temperature of the regeneration bed. Under the same oxygen concentration conditions, the regeneration effect of oxy-fuel combustion was consistent with that of air regeneration. The oxygen concentration was positively correlated with the regeneration effect and reaction conversion rate. By adjusting the composition of the regeneration gas, the coke efficiency, coke load, and processing capacity of the regenerator could be flexibly adjusted to improve the overall economic efficiency of the plant. The oxy-fuel combustion regeneration technology could not only improve the operation flexibility of the plant, but also realize CO2 capture of FCC unit.
