中文摘要：

以生活垃圾衍生燃料RDF（refuse derived fuel）为原料,在750℃下进行了催化气化-改质实验,研究了氧气供应量、Ni基催化剂组分等操作要素对合成气生成特性的影响。结果表明：氧气供应量ER（equivalent ratio）的增加可以提高碳素转化率和冷气体效率;在Ni基催化剂中添加Mg、Ce、K、Ca和Zn等金属助剂可以有效改善改质催化性能,促进焦油分解,提高有效气体收率。在750℃温度条件下,控制供氧量ER=0.04时,通过催化气化-改质处理,可以从RDF获得H2体积分数约29.00%的清洁合成气,冷气体效率和碳素转化率分别为44.41%和82.41%,合成气收率可达0.244 m3·kg-1（RDF）。

英文摘要：

In this study,a series of catalytic gasification-reforming experiments were conducted at 750 ℃ using refuse-derived fuel（ RDF） as a raw material,and the effects of the operating parameters,including the addition of oxygen ER（ equivalent ratio） and Ni-based catalyst components,on the characteristics of synthesis gas generation were studied. The obtained results indicated that the increase of oxygen addition could improve the carbon conversion and cold gas efficiency. The addition of metal additives such as Mg,Ce,K,Ca,or Zn to the Nibased catalyst was beneficial for improving the catalytic performance,promoted tar decomposition,and increased the synthesis gas yield. At 750 ℃ and upon addition of oxygen at ER = 0. 04,clean synthesis gas containing about29. 00% of hydrogen could be generated from RDF via catalytic gasification reforming. The cold gas and carbon conversion efficiency were 44. 41% and 82. 41%,respectively,while the gas yield was 0. 244 m3·kg-1（ RDF）.
