大庆炼厂重油催化原料油裂化性能研究Ⅰ.裂化原料油催化裂化试验

STUDY ON THE BEHAVIOR OF DAQINING REFINERY RFCCU FEEDSTOCK I. THE FCC TEST OF CRACKING FEEDSTOCK

大庆炼厂重油催化裂化装置所用裂化原料油性能比较复杂，为了能够预测该装置在不同原料配比和不同操作条件变化时的规律，应用同轴式催化裂化试验装置，在ＺＣＭ－７超稳剂上研究了温度分别为５００℃，５１５℃，５３０℃及剂油比为５，６，７三个条件下，所选三个代表性油样的裂化性能。

The feedstocks of Daqing Refinery RFCCU are of complex components. In order to estimate the RFCCU under different operating conditions and with different feedstocks, we have tested with temperature 500 ℃,530 ℃, and the cat to oil is 5,6,7 respectively, about three typical feedstocks on ZCM 7 using cracking catalyst. These results will be applied to the establishment a mathematical model which may fit Daqing Refinery RFCCU.
