虽然催化裂化技术在多年后仍会是炼油厂的核心技术之一 ,但目前面临的问题不容忽视 ,诸如原料质量变差以及所需产品的变化且要符合新环保法规对排放的要求。世界催化裂化总能力为 6 .5亿吨 /年 ,而渣油催化裂化已占其中的 2 5 %。加工渣油时 ,原料注入技术是关键 ,原料雾化不好 Although FCC technology will remain one of the refinery’s core technologies for many years, the current problems can not be ignored, such as the deterioration of raw material quality and the change of required products and the emission requirements of the new environmental protection laws and regulations. The world’s total catalytic cracking capacity is 650 million tons / year, while residue catalytic cracking has accounted for 25%. When processing residue, raw material injection technology is the key, raw material atomization is not good
