空速对焦化汽油产物分布的影响

Effects of Weight Hour Space Velocity on the Products Distribution of Fushun Delayed Coking Gasoline

以抚顺焦化汽油为原料,采用小型固定流化床为反应装置,考察了空速对产物分布、轻油产品族组成、干气组成和液化气组成影响规律,同时通过实验数据建立了空速与干气收率、液化气收率、焦炭收率、轻油收率和总收率的关系式。实验结果表明,随着空速的增加,焦炭、干气和液化气收率逐渐下降,轻油收率逐渐增加,芳烃含量缓慢下降,而饱和烃含量基本没有变化。

By using delayed coking gasoline obtained from fushun as a feedstock,the effects of weight hour space velocity （WHSV）on the products distribution and composition of light oil and dry gas and liquefied petroleum gas were researched in a small confined fluidized bed reactor over RGD-1 catalyst and CC-20D catalyst. At the same time the equation of dry gas yield,liquefied petroleum gas yield,coke yield,light oil yield and total yield with WHSV were established through experimental data.The experimental results show that with the increasing of WHSV,the yield of coke,dry gas and liquefied petroleum gas gradually decreases,light oil yield gradually increases,aromatics amount drops slowly and saturated hydrocarbon amount is almost unchanged.
