Abstract
【解決手段】 細孔性炭素材に貴金属の1種以上または貴金属とランタニド金属の各々1種以上が担持されていることを特徴とするメタン水蒸気改質用触媒を用いる。
【選択図】図2
Description
発生水素量=MH/(MH+MM+MCl+MC2)×100(%)
となる。
実施例2:Ru/SWNH(Ru 2wt%担持)
実施例3:Eu・Pt/SWNH(Pt 4wt%、Eu 0.1mmol/SWNH
1g当たりを担持)
調製に際しては、たとえば実施例1の場合にはSWNH 96mgにPtの量で8mgのPtアンミン(IV)溶液を加えて1時間攪拌した後、ろ過を行い10mLの純水で3回洗浄を行った。そののち、フィルター上に残った試料を窒素流通下で乾燥させ(室温)、Pt/SWNH触媒を得た。
比較例2:Eu/SWNH(Eu 0.1mmol/SWNH 1g当たりを担持)
比較例3:Ni/Al2O3(Ni 4wt%担持)
比較例4:Ru/Al2O3(Ru 4wt%担持)
これらの触媒を用いて、理論水素SV=1250hr-1、水蒸気メタン比3.5の条件下にメタン水蒸気改質反応を行った。なお、測定装置にはアジエント社のマイクロガスクロを使用した。
