大庆减压蜡油在混合分子筛裂化催化剂上催化裂化的研究

A CATALYTIC CRACKING STUDY OF DAQING VACUUMWAX OIL ON THE MIXED ZEOLITES CATALYST

本文研究了在一种Y型分子筛催化剂中掺和另一种Y型分子筛催化剂时,大庆减压蜡油的裂化性能。通过试验证明了两种分子筛催化剂混合使用时,存在着最佳混合比,本试验找到了这个混合比。本文进一步对存在最佳混合比的实验现象提出了解释。本文还提出,协同理论不仅适用于单相催化剂而且也适用异相催化剂,在异相催化剂上存在着自组织现象和协同作用。

Cracking characteristics of Daqing vacuum wax oil are investigated by using laboratory catalytic cracking unit which is on the mixed Y - zeolites catalysts. The results show there may be an optimum ratio when two catalysts are used. We consider that the synergism is not only in the identical phase catalyst but also in the different phase catalysts.
