Abstract: The noxious gas H2S generated during oil shale retorting pollutes natural environment and harms human health. A numerical model was established according to experimental data for the research on the release characteristics of H2S in retorting gases. Aspen Plus was used for the calculation，and the result approximately complied with that of the experiment. The effects of final retorting temperature on the release amount and rate of hydrogen sulfide were analyzed. For a specific temperature range，the amount of H2S release and total gas release increased as final retorting temperature increased. The calculation result was in good agreement with the experimental data，providing theoretical foundation for the conversion and distribution of sulfur during oil shale retorting.

摘要： 油页岩干馏过程中产生的以H2S为主的有害气体污染环境、危害人体健康。针对干馏气中H2S的释放特性进行理论研究，结合试验数据进行油页岩干馏过程中H2S释放特性的数值模拟。所建立模型采用Aspen Plus进行模拟计算，模拟结果与试验结果基本相符。通过模拟计算分析了干馏终温对H2S释放量和释放速率的影响。在特定温度段内，H2S气体释放量和总气体释放量均随干馏终温的升高而增加。模型计算结果与实验值相近，可为研究油页岩干馏过程中硫的转化与分布特性提供有益参考。
