| 摘 要： | 甲烷的二氧化碳重整制合成气是近年来甲烷催化转化的一个重要方面，而所用催化剂的积炭问题仍是影响催化剂活性和寿命的主要因素之一．近年来，对催化剂表面的积炭形式有一些报道［１］，但对积炭的种类及其与催化剂活性的关系很少有报道．本文从经低温焙烧的Ｃｏ／Ａｌ２...

| Abstract: | Temperature programmed oxidation combined with massspectrometry(TPOMS) technique has been used to investigate the burning of carbon deposited on the Co/Al2O3 catalysts during reforming of methane with CO2. Obvious coke and carbon deposition sites were found on the 13%Co/Al2O3, while on the 8%Co/Al2O3 only coke deposition site. The total amount of carbon and coke deposites was much greater on the surface of 13%Co/Al2O3. It is considered the reason that 13%Co/Al2O3 catalyst showed better catalytic activity and stability than the other one. |
