以甲苯为生物质气化焦油的模型化合物，以Ni-CeO2/SBA-15为催化剂，在自行搭建的固定床电化学催化（电催化）水蒸气重整实验台上进行了甲苯的电催化水蒸气重整实验，考察了电流强度、反应温度和水/碳摩尔比（S/C）对甲苯转化率、产气组成的影响，并对该催化剂进行了长时间活性测试。结果表明，电流的引入可以显著提高催化剂对甲苯的转化效率；在电流为4 A、反应温度为800℃、S/C为3时，甲苯转化率可以达到94.7%。

Electric current enhanced catalytic steam reforming of toluene, which was selected as the model compound of biomass gasification tar, was performed by a fixed-bed electrochemical catalytic steam reforming experimental set using the Ni-CeO2/SBA-15 catalyst. Experiments were performed to reveal the effects of several factors on the toluene conversion and product gas composition, including the electric current intensity, reaction temperature and steam/carbon (S/C) ratio. Moreover, stability test of the catalyst was conducted over a long experimental period. The results indicated that the presence of the electric current enhanced the catalytic activity remarkably. The toluene conversion reached as high as 94.7% under the electric current of 4 A, temperature of 800 °C and S/C ratio of 3.
