摘　　要：在实验基础上对Bio-SR工艺应用于天然气脱硫净化机理进行了分析。通过单因素实验,考察了不同原料气浓度、初始Fe3+浓度、吸收液喷淋量、停留时间、pH值及压力变化等因素对脱硫效率的影响,初步确定了适宜的控制参数。结果表明,该工艺是由氧化亚铁硫杆菌和Fe3+协同催化氧化脱除H2S,因而其效率优于单纯的液相Fe3+化学氧化作用;氧化吸收反应速率远大于气液传质速率,气液传质速率为影响天然气脱H2S净化吸收的限速步骤。Based on experiment,we analyzed the desulfuration mechanics of Bio-SR applied in natural gas.Single factor test was designed to test the variety of desulfurization efficiency under different concentrations of inlet gas,initial [Fe3+],amount of absorption solution,reaction time,pH and pressures etc,and optimal proper operating parameters were gained initially.Because of the co-operating of Thiobacillus ferrooxidans and [Fe3+],as a result,its efficiency is better than the pure [Fe3+].The experimental results showed that oxidation reaction rates were quicker than rates of gas-liquid mass transfer,and the subsequent was the dominant influencing factor of desulfurization efficiency.
