Reaction Formula and Phenomenon of Desulfurization in Refining1. **饱和类含硫化合物(硫醇、二硫化物和硫醚)** - 反应方程式:在加氢精制条件下,\(C - S\)直接裂化成饱和烃和硫化氢(以硫醇\(C_{2}H_{5}SH\)为例)\(C_{2}H_{5}SH + H_{2}=C_{2}H_{6}+H_{2}S\)。 - 现象:饱和类含硫化合物较容易脱除,在加氢精制过程中,在催化剂和氢气的作用下,\(C - S\)键断裂,生成相应的饱和烃和硫化氢气体。 2. **噻吩** - 反应方程式: - 直接加氢氢解脱硫路径:\(C_{4}H_{4}S + 4H_{2}=C_{4}H_{10}+H_{2}S\)(产物为丁烷和硫化氢); - 先加氢饱和后加氢氢解脱硫路径(最终产物同样为丁烷和硫化氢)。 - 现象:噻吩在加氢精制过程中,通过两种路径进行加氢脱硫反应,最终都转化为丁烷和硫化氢,在反应过程中,需要在适宜的温度、压力、催化剂等条件下,使噻吩中的硫原子以硫化氢的形式脱除。 3. **苯并噻吩** - 反应方程式:苯并噻吩经过加氢脱硫后产物主要含有乙苯和少量的二氢苯并噻吩,最终产物为乙苯和硫化氢,但具体反应历程较为复杂。 - 现象:在加氢精制反应条件下,苯并噻吩逐步反应,最终生成乙苯和硫化氢,反应过程中,分子结构发生变化,硫原子逐步被脱除。...
