摘要: |
通过文献调研、实验研究和重油催化裂化工业装置现场采样,对传统重油催化裂化提升管反应器进行了研究。 结果显示,传统重油催化裂化普遍存在反应时间过长、平均催化剂活性低和选择性差及不同反应组分之间存在恶性 竞争等弊端。在此基础上,提出了两段提升管催化裂化新概念,并分析了其技术优势。 |

Abstract: |
According to the experimental results, industrial test data, as well as literature information,the traditional riser fluid catalytic cracking ( RFCC) reactor was studied. The shortcomings of traditional RFCC reactor, such as the overlong reaction time, the low average activity and selectivity of catalyst, and the detrimental competitive adsorption and reaction among different feedstocks, were pointed out. Based on the analysis,the new concept of two-stage riser fluid catalytic cracking (TSRFCC) was proposed, and the advantage of the TSRFCC technology was analyzed |
Key words: catalytic cracking of heavy oil riser reactor two-stage riser fluid catalytic cracking (TSRFCC) |
