| 摘 要： | 对催化裂化回炼油三段窄馏分的供氢能力进行测定，选取供氢能力最强的一段进行加氢处理，以加氢后的催化裂化回炼油窄馏分为焦化供氢剂，通过中试试验考察其供氢效果。结果表明：三段窄馏分中，小于400 ℃馏分供氢能力最强；加氢处理能够进一步提高其供氢能力，以加氢后回炼油小于400 ℃馏分作为供氢剂能够使液体收率提高1.32百分点，焦炭收率降低2.45百分点。

INVESTIGATION OF HYDRO-TREATED FCC RECYCLE OIL AS HYDROGEN DONOR FOR COKING REACTION |
| |
| Abstract: | The hydrogen-donating indexes of the three narrow fractions of FCC recycle oil were measured. Among these fractions, the one which has the highest hydrogen-donating index was chosen to be used as hydrogen donor after being hydro-treated. The hydrogen-donating effect of the hydro-treated fraction was investigated in pilot tests. The results showed that the fraction (IBP-400℃) has the best hydrogen-donating capacity among the three narrow fractions of FCC recycle oil, and the hydrogen-donating capacity can be further improved by hydrotreatment. When the fraction (IBP-400 ℃) hydrotreated was used as hydrogen donor, the liquid yield can increase by 1.32% and coke yield can decrease by 2.45%. |
