摘要(Abstract):

煤电化学气化相对于传统的煤气化具有反应条件温和、工艺简单以及环境友好等诸多优点,但由于煤结构与成分的复杂性,导致煤电化学气化的研究多年来一直未有较大进展。以活性炭代替煤,在不同工艺条件下研究了活性炭电化学气化的过程中电流随时间的变化以及阳极气体成分与含量。研究结果表明:活性炭电化学气化过程中,阳极的气体产物主要为CO_2,其中含有少量的CO,两者的比例相差1~2个数量级;随着温度、电解电位以及活性炭浓度的提高,活性炭电化学气化反应的电流和气体产量均增加,最佳硫酸浓度为1 mol/L.
Coal electrochemical gasification has many advantages such as mild reaction conditions, simple process, and environmental friendliness compared with traditional coal gasification. However, owing to the complexity of coal structure and composition,the research on the electrochemical gasification of coal has not made much progress for many years. In this paper, activated carbon was used instead of coal to study the current change with time and the composition and content of gas in anodic cell during the electrochemical gasification of activated carbon under different process conditions. The results show that during the electrochemical gasification of activated carbon, the gas product of the anode was mainly CO_2, and a small amount of CO, and the ratio of the two differed by 1-2 orders of magnitude; with the increase of temperature, electrolytic voltage and concentration of activated carbon, the current and gas production of the electrochemical gasification reaction both increased, and the optimal sulfuric acid concentration was 1 mol/L.
