To operate H2 station efficiently, we have researched combustion catalysts to generate heat using residue gas as fuel. Catalytic combustion was performed by Mn-substituted La, Ba, Sr –hexaaluminate. Activity test was carried under two conditions: the first condition (1% CH4, 20% O2 in N2 balance) and the second one containing H2 (1% CH4, 6% H2, 20% O2 in N2 balance). Total flow rate was 1,000cc/m and GHSV was 120,000 cc/h∙g-cat. By adding H2 in fuel, conversion of methane shifted to low temperature. For all the catalysts tested, BaMnAl1O19 showed good CH4 conversion through adding H2 in fuel. Extended Abstract Status: File Uploaded | ||
