| 7. | Simulating results reveal that hydrodynamics of catalysts in riser reactor is very complex due to the effect of injection and catalysts backmix dramatically near the nozzle , reaction products unevenly distributie along the riser height , there exists apparently temperature gap between gas - phase and solid - phase near the nozzle and the temperture of two phase is nearly equal at middle - top part
模拟结果表明，由于原料油射流的影响，提升管反应器内催化剂颗粒的流动特征非常复杂，在喷嘴附近的催化剂颗粒存在明显的滑落返混；裂化产物浓度沿提升管存在非均匀分布；气粒两相间温差在喷嘴附近显著，在中上部气粒两相温度几乎相等。 |
| 8. | Abstract : large time delay exists in complicated practical processes . for example , in fccu ( fluidized catalytic cracker unit ) reactor - regenerator , the feed is preheated through heat exchanging from fractional column slurry , thus results in large time delay . a predictive control system is designed for such processes , where the kernal algorithm is dynamic matrix control . application results show that the control behavior is improved than original pid control
文摘:实际的复杂工业过程，往往具有大的时滞，例如：炼油厂催化裂化装置的反应再生系统，其原料油预热通过油浆换热实现，因此时滞特别大.本文针对这一类大的时滞过程，设计了以动态矩阵控制为核心算法的预测控制系统，运行实践表明：这一控制方案比原pid控制在控制质量上有较大提高 |

| 10. | It is shown that the gam and alsphene in the seven catalytic stocks were not very high except in residual oil ; the saturate hydrocarbons in all seven were hig her ; aromatic contents were lower except in slurry oil and recycle oil , therefore , t he s even catalytic stocks except slurry oil and recycle oil are all good feedings of catalytic cracking unit
分析测定结果表明，这7种催化原料油除常渣外，胶质沥青质含量均不高；饱和烃含量均较高；芳烃含量除油浆、回炼油外，其余原料含量均较低，所以除油浆、回炼油外，均是作催化裂化的良好原料。 |
