以萘/苯为生物质气化焦油模型化合物，对Ni/MgO催化剂进行了循环使用试验。焙烧和还原的Ni/MgO催化剂均表现出相同的催化活性，而与H2预处理无关。用10%O_2/Ar混合气体在873 K下氧化40 min，可使废催化剂上的碳物种完全氧化。该催化剂表现出稳定的活性（碳基转化率：平均值为1.5%）。55%）。然而，催化剂在循环使用测试（蒸汽重整→氧化→蒸汽重整）期间失去其活性。
The cycle usage test of Ni/MgO catalyst for the steam reforming of naphthalene/benzene as model tar compounds of biomass gasification were conducted. Both calcined and reduced Ni/MgO catalysts showed same catalytic activities regardless with H2pretreatment. The carbon species on used catalyst could be completely oxidized by 10% O2/Ar mixture at 873K for 40min. This catalyst showed stable activity (carbon based conversion: av. 55%) at 1073K for 10h. However, the catalyst lost its activity during cycle usage tests (steam reforming→oxidation→steam reforming).
