摘要
研究了催化裂化油浆在一种新型交联剂存在下的交联缩合反应过程,考察了交联剂用量、反应温度和反应时间对缩合油浆黏度和族组成的影响,确定了适宜的反应条件：交联剂用量1%-1.5%,反应温度135℃以下,反应时间为60 min.研究结果表明,油浆经过交联缩合反应后,缩合油浆的粘度明显增大,甲苯不溶物的含量增多,正庚烷沥青质含量变化与油浆粘度变化一致.以油浆粘度为表征指标,与其它交联剂相比,本研究所用交联剂缩合效果显著.
Crosslinking condensation reaction of FCC slurry with a new crosslinking agent has been studied. The effects of various factors, such as the content of crosslinking agents, reaction temperatures and times, on the viscosity of FCC slurry and the content of different components were investigated, so that the optimum reaction condition was established. The experimental results indicate that the viscosity of FCC slurry and the content of toluene insolubles increased remarkably after condensation reaction. Moreover, the change of content of n-heptane asphaltenes accorded with the change of viscosity of slurry. According to the viscosity of condensation slurry, better quality was obtained using the new crosslinking agent compared with others.
