总结了多产丙烯和低硫燃料油组分的催化裂化与加氢脱硫技术(marine fuel and propylene,MFP)的工业试验装置主要技术内容和工艺特点。以140万t/a重油催化裂化装置为试验对象,对装置的空白标定数据、80%藏量标定数据进行了分析。结果表明,与空白标定相比,MFP工艺实现了液化气烯烃度大幅增加,低碳烯烃产率和选择性得到改善,同时实现了抑制干气和焦炭的生成,使多环芳烃最大程度保留在燃料油组分中,产品性质稳定。

Main technical content and process characteristics of the industrial test plant for the catalytic cracking and hydrodesulfurization technology (MFP) that can produce more propylene and low-sulfur fuel oil components are summarized.Taking the 1.4 million t/a heavy oil catalytic cracking unit as the test object,the blank calibration data and 80% reservoir calibration data of the unit are analyzed.Results show that compared with the blank calibration,MFP process can greatly increase the olefin degree of liquefied gas,improve the yield and selectivity of low-carbon olefins,and inhibit the formation of dry gas and coke.Polycyclic aromatic hydrocarbons are retained in the fuel oil components to the greatest extent,and the product has a stable property.
