摘要/Abstract

摘要： 在高温固定床反应器中，对木屑半焦进行高温水蒸气气化制备富氢燃气。在温度700~900 ℃、水蒸气流量0.11~0.32 g/（min·g）（以焦炭计，下同）条件下，研究了气化温度和水蒸气流量对水蒸气气化制备燃气中的氢气含量、产气率、热值以及燃气中各组分体积分数的影响。研究表明：水蒸气通入过量会造成燃气热值的降低；在气化温度900 ℃、水蒸气流量0.32 g/（min·g）时，燃气中氢气达到62.53%，燃气热值为8.99 MJ/Nm³，燃气产率为2.75 L/g。利用容积反应模型和未反应收缩核模型拟合试验数据得到了相应的动力学参数，发现未反应收缩核模型比容积反应模型可以更好的描述木屑半焦的水蒸气气化行为，容积反应模型所得到活化能为88.67 kJ/（mol·K），指前因子为2 976.55 min^-1，未反应收缩核模型所得活化能为91.78 kJ/（mol·K），指前因子为2 872.82 min^-1。

Abstract: Steam gasification of sawdust char for the production of hydrogen-rich gas was studied in a high-temperature fixed bed reactor. Experiments were carried out at 700-900℃ with steam flow rate of 0.11-0.32 g/(min·g)(based on the char, the same below).The effects of temperature and steam flow rate on the volume fraction of H₂,gas yield, heat value and compositions were studied. The results showed that the excess steam led to a decrement of the gas heat value. Under the reaction conditions of temperature 900℃ and the steam flow rate was 0.32 g/(min·g), the volume fraction of H₂ reached the maximum(62.53%), the heating value of the fuel gas was 8.99 MJ/Nm³ and the gas yield was 2.75 L/g. And the homogeneous volumetric model and shrinking core model were employed to obtain the corresponding kinetic parameters. The shrinking core model fitted the experimental data better than the homogeneous volumetric model.The acitivity energy and the pre-exponential factor obtained with homogeneous volumetric model were 88.67 kJ/(mol·K)and 2 976.55 min^-1. The activity energy of the shrinking core model was 91.78 kJ/(mol·K)and the corresponding pre-exponential factor was 2 872.82 min^-1.
