An efficient analytical method combining pyrolysis and capillary GC/MS has been developed for determination and quantitation of targeted polycyclic aromatic *** limit of detection ranged from 0.29 μg/g to 43.46 μg/g,and repeatability values were between 0.1% and 8.2% for blank spiked samples and between 0.1 % and 9.8% for real samples of heavy *** application of the proposed method in hydrotreating processes,it has been found out that heavy oils before and after the specified hydroprocessing treatment exhibited a diverse PAHs distribution which might be determined by the discrepancy in their intrinsic contents and hydrogenation ***,the hydrogenation reactivity of different polycyclic aromatic hydrocarbons was further investigated and discovered to be more interrelated to molecular structure and rings alignment or conjugation mode.

Commercial Application of CPP for Producing Ethylene and Propylene from heavy Oil Feed

引用

China Petroleum Processing & Petrochemical Technology 2003年第1期5卷 19-22页

作者： Hou Dianguo Xie Chaogang Wang Xieqing(Research Institute of Petroleum Processing, Beijing 100083) Res. Inst. of Petroleum Processing Beijing 100083 China

A new process named CPP (Catalytic Pyrolysis Process) for producing ethylene andpropylene from heavy oil feedstock has been developed. The catalyst CEP was specially designedfor this process, which has bi-functional catalytic activities for both carbonium ion reaction andfree radical reaction, so as to maximize the yields of ethylene and propylene. The commercial trialshowed that the yield of ethylene and propylene was 20.37% and 18.23% respectively inmaximum ethylene operation with Daqing AR as feedstock, and the yield of ethylene and propylenewas 9.77% and 24.60% respectively in maximum propylene operation by using the same *** with steam cracker, the feed cost of CPP is much lower for producing ethylene andpropylene.
