摘要:采用固定床等温积分反应器,以不同组成的含硫化合物作为模型化合物,在消除催化剂内外扩散影响的基础上,考察了反应温度、苯并噻吩浓度、噻吩浓度以及硫化氢分压对加氢脱硫反应速率的影响,建立了苯并噻吩和噻吩单独加氢和共加氢的LHHW型反应动力学方程,并表明以真实的原料组成和在实际操作条件下进行动力学实验的重要性。
Hydrodesulfurization of thiophene and/or benzothiophene was carried out on Co-Mo/γ-Al2O3 catalyst in an isothermal integral reactor under different reaction temperatures, sulfur-containing compound concentrations and hydrogen sulfide partial pressures. LHHW reaction kinetic equation for hydrodesulfurization of thiophene alone or together with benzothiophene was established. The importance of kinetic study using real composition of raw materials under actual industrial operating conditions has been demonstrated.
