Abstract
Description
上記した実施例および比較例において使用した改質触媒(CuO単独触媒とCu/ZnO触媒)を用いて、実施例1および比較例1と同一の条件で触媒性能の耐久試験を実施した。その結果を図3に表す。図3においては、横軸は運転時間(改質反応器1から改質ガスが安定的に排出され始めた時点からの経過時間)を表し、縦軸は当該運転時間が経過した時点における全メタノール反応率を表す。本発明に係るCuO単独触媒の場合には、700時間経過時点においても全メタノール反応率は約99%と高い値を維持していた。これに対し、Cu/ZnO触媒の場合には、全メタノール反応率は、運転開始初期には約99%と高い値を示している一方、時間経過にともなって徐々に低下する傾向を示し、700時間経過時点では、80%程度まで低下している。いずれの触媒を用いた場合にも、改質反応部3における高温領域のピーク温度は約400℃程度に達していたが、Cu/ZnO触媒は、シンタリングによる触媒活性の低下に起因して、全メタノール反応率が低下したものと考えられる。
