大庆催化油浆受热相分离行为的研究

STUDY ON PHASE-SEPARATION BEHAVIOR OF DAQING FCC SLURRY

借助于热台显微镜 ,对大庆油浆受热相分离行为进行了考察。通过在有氧、无氧条件及不同温度下对大庆油浆受热相分离行为的研究 ,并与之基本物性相互关联 ,从微观上探讨油浆的生成机理。实验表明 ,油浆中重组分含量高时 ,有氧条件下生焦就会加剧 ;同时高温短时间或是低温长时间下生焦倾向就会加大 。

By using polyfunctional microscope, the behavior of phase separation of Daqing FCC slurry was investigated The effects of oxygen and temperature on the phase separation and coke formation of Daqing FCC slurry were studied Based on the experimental results and physicochemical properties of Daqing FCC slurry, the mechanism of phase separation and coke formation is discussed On the one hand, the experimental results show that the heavier the composition is, the easier the coke formation is At the same time, with oxygen or under high temperature or in longer time, the catalytic slurry formats coke easily On the other hand, it will retard coke formation under wider aromatic distribution of catalytic slurry
