Abstract

There is a residue gas which contains CH₄ unconverted in LNG reformer and H₂ unrefined in PSA, when H₂ station produces H₂ through LNG reformer. 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, and 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, BaMnA ₁₁O₁₉ showed good CH₄ conversion through adding H₂ in fuel.
