高掺渣油比催化裂解催化剂RMMC-1的开发

为提高多产低碳烯烃催化剂应对装置掺炼渣油的能力，开发了新一代催化裂解催化剂RMMC-1。RMMC-1采用大孔结构（9～13 nm）的基质，改善催化剂孔分布，强化基质的炭捕集区来提高催化剂活性中心可接近性，增加对渣油等大分子烃的一次裂化。RMMC-1催化剂对渣油等重质油的催化裂解能力强，实现多产丙烯目的的同时，液态产品质量略有改善。

RMMC-1 Catalyst for Catalytic Cracking of High Residue Blending Portion

In order to improve the ability of the catalysts producing low carbon olefin coping FCCU refining residuum, a new generation of catalytic cracking catalyst RMMC-1 was developed. The matrix of RMMC-1 had more pores with the sizes of 9-13 nm, which were the trapping areas. So the coke yield was lower than contrast catalyst. Due to RMMC-1 with high capacity to crack residue oil, more propylene could be obtained and liquid product quality was improved slightly.
