Experimental results show that the feeding rate of liquid into the moving-bed column, liquid rising velocity of riser and height of particles in the moving-bed column have important influence on particles transport velocity, and the reason is given to the system pressure balance.

实验结果表明，密实移动床的进液量、提升液表观操作流速和密实移动床中的交换剂高度是影响固体颗粒提升速率的因素，并从压力平衡的角度对实验现象进行了解释。

With the riser height increases, the mass fraction of heavy oil reduces, while the weight of gasoline, LPG, gas and coke has been increasing.

随着提升管高度的增加，重油的质量分率降低，而汽油、液化气、气体和焦炭的产率增加。

With increasing riser height, the average solid holdup at various axial locations of the riser decreases and becomes more uniformly distributed along the riser height.

提升管高度增加，提升管各高度截面上的平均固含率减小，其轴向分布也更加均匀。

The results show that the radial distribution of particle velocities always becomes less uniform along the riser height and finally reaches a parabolic profile in the upper section.

结果表明：沿提升管轴向，颗粒速度径向分布不均匀性逐渐增加，并最终趋于较为稳定的抛物线分布；

It is found that, with increasing superficial gas velocity, the axial pressure gradients are not always kept approaching a uniform distribution along the riser height;

结果表明，在表观气速增大的过程中气固提升管中的轴向压力梯度并非总是不断趋于均匀分布；

When the riser height is over 10 meters, variations of gasoline concentrations depend on the properties of feedstock and operating conditions.

在提升管高度为10米以下时汽油浓度随提升管高度增加而迅速增加，超过10米时，汽油浓度是增加还是减少取决于原料油物性和操作参数。
