渣油化学组成对催化裂化反应的影响

EFFECT OF CHEMICAL COMPOSITIONOF RESIDUA ON FCC REACTION

利用超临界流体萃取分离技术将大庆、胜利、孤岛、大港、华北、辽河等６种渣油进行了抽出率分别为３０％、４０％、５０％、６０％的切割分离，对各抽出油的主要性质和结构组成进行了分析，并在固定流化床反应装置上进行了催化裂化反应，对反应结果与抽出油的组成进行了关联，得到了一些重要的结论。

Six domestic residua,Daqing,Shengli,Gudao,Dagang,Huabei and Liaohe,were separated into four fractions:30%,40%,50%,60% by Supercritical Fluid Extraction and Fractionation(SFEF)technology.The properties and composition were obtained.The fluid catalytic cracking reaction was carried out in a fixed fluidized bed reactor using RHZ200 catalyst.The composition data and product distribution were correlated and discussed.
