简介：在FCC汽油的硫混合物的形成上的石蜡的效果在在从400～500的温度联合起来的一张小规模的固定的使流体化的床(FFB)上被学习，重量时时10h-1的空间速度(WHSV)，和6的催化剂/油比率。结果证明在FCC汽油包含的C4-C6石蜡能与H2S反应主要形成thiophenes，alkyl-thiophenes以及thiols的部分数量，当象heptene那样的大分子的石蜡能与形成benzothiophenes的氢硫化物反应时。在不同催化剂上在不同温度形成的硫混合物的数量与在化工物品的石蜡的集体部分成比例，与在REUSY催化剂超过上形成的硫混合物的数量，那些在石蜡变换的度上由于催化剂性能的效果和催化剂的影响在形状上形成了选择沸石催化剂。因为为硫的形成的热力学、运动的常数上的温度的影响，在450点的最大值和在400点的最小象在石蜡变换degree.Based上一样加重在上的产生的硫混合物和他们到达的增加的数量上述学习，为与H2S在FCC汽油在石蜡的反应之上产生的硫混合物的预言的一个反应网络和一个模型被建立。
