催化改性活性碳纤维降低NO的实验研究

在微型反应器中对负载离子聚丙烯腈基活性碳纤维（ACF）进行了脱除NO的实际效果对比，定量测定在不同温度下它们与NO的反应产物，通过程序升温脱附（TPD）、热重（TG）及扫描电镜（SEM）的研究，为反应机理探索和催化剂筛选提供了依据。结果显示，金属离子的引入可大大提高催化活性。考察了所选负载铜离子ACF在不同气氛下的变化规律，并进行了化学动力学计算。实验结果表明，以聚丙烯腈基活性碳纤维为载体负载铜离子的ACF具有较高催化还原活性。活性碳纤维既作载体又作还原剂，它本身的性质十分重要。

Experimental Study on Reduction of Nitrogen Oxide by Catalytic Modified Activated Carbon Fibers

The reaction of NO with activated carbon fiber (ACF) modified by Cu was carried out in a micro reactor system and the products of this reaction were analyzed.By use of TG?TPD and SEM,Cu/C was evaluated and selected successfully.Moreover,the influences of O 2,O 2+CO,and temperature on NO reduction were examined.The study was concentrated on the kinetics research of various ACF in air.The test results show that NO concentration may be reduced effectively,Cu/C shows excellent performance.ACF acts as both supporter and reductant and its surface properties become very important.
