Abstract The pyrolysis char from waste peat with impregnated metal (Fe/Ni/Ca) were investigated for catalytic reforming of toluene in a laboratory dual-stage reactor. The prepared catalysts were examined in microstructure and textural characterization to analyze catalytic performance and stability. The results indicated that under the optimized conditions, the toluene conversions are greater than 92.7% for three types of peat char-supported catalysts, and the maximum molar ratio of syngas (CO + H2) can reach up to 94.7% using Ni/peat char catalyst. The promising results demonstrated that the H2 and CO are favored for Fe/peat char and Ni/peat char catalysts while the H2 and CH4 are favored for Ca/peat char catalyst. After 320 min of experiment, the mol% of syngas decreased by less than 30% for three types of peat char catalysts. Significantly, peat char (C-SiO2) as a carrier can enhance the performance of catalyst through interaction with the metal, and it can be used as an adsorption carrier to absorb unreacted toluene. Such peat char-supported catalysts are thus promising for tar conversion and useful syngas production.

废泥炭负载Fe/Ni/Ca催化剂上甲苯重整反应及失活机理

摘要 在实验室双级反应器中研究了浸渍金属（Fe/Ni/Ca）的废泥炭热解焦对甲苯的催化重整。对制备的催化剂进行微观结构和结构表征以分析催化性能和稳定性。结果表明，在优化条件下，三种类型的泥炭炭负载催化剂的甲苯转化率均大于92.7%，使用Ni/泥炭炭的合成气（CO+H2）最大摩尔比可达94.7%催化剂。有希望的结果表明，H2 和 CO 有利于 Fe/泥炭炭和 Ni/泥炭炭催化剂，而 H2 和 CH4 有利于 Ca/泥炭炭催化剂。实验 320 分钟后，对于三种类型的泥炭炭催化剂，合成气的 mol% 降低了不到 30%。显着地，以泥炭炭（C-SiO2）为载体，通过与金属的相互作用提高催化剂的性能，可作为吸附载体吸附未反应的甲苯。因此，这种泥炭炭负载催化剂有望用于焦油转化和有用的合成气生产。
