Abstract:
We investigated high catalytic activity of Ni/HZSM-5 catalysts synthesized by the impregna-tion method, which was successfully applied for low-temperature steam reforming of bio-oil. The influences of the catalyst composition, reforming temperature and the molar ratio of steam to carbon fed on the stream reforming process of bio-oil over the Ni/HZSM-5 catalysts were investigated in the reforming reactor. The promoting effects of current passing through the catalyst on the bio-oil reforming were also studied using the electrochemical catalytic re-forming approach. By comparing Ni/HZSM-5 with commonly used Ni/Al2O3 catalysts, the Ni20/ZSM catalyst with Ni-loading content of about 20% on the HZSM-5 support showed the highest catalytic activity. Even at 450 oC, the hydrogen yield of about 90% with a near complete conversion of bio-oil was obtained using the Ni20/ZSM catalyst. It was found that the performance of the bio-oil reforming was remarkably enhanced by the HZSM-5 supporter and the current through the catalyst. The features of the Ni/HZSM-5 catalysts were also investigated via X-ray diffraction, inductively coupled plasma and atomic emission spectroscopy, hydrogen temperature-programmed reduction, and Brunauer-Emmett-Teller methods.

摘要:
利用浸渍方法制备的Ni/HZSM-5催化剂在生物油低温水蒸汽重整合成中表现了较高的催化活性. 探讨了催化剂的组成、重整温度、水碳比例对重整过程的影响.在电催化重整研究中,发现催化剂上通过的电流可以显著地促进生物油水蒸汽重整.通过对不同负载量的Ni/HZSM-5催化剂和Ni20/Al2O3催化剂的催化活性的比较,NiO在催化剂中负载量为20%(Ni20/ZSM)时表现出了最高的催化活性; 即使在450 oC时, 在Ni20/ZSM催化剂上也可以达到碳转化率接近完全, 氢气产率约为90%的效果. 利用XRD、ICP/AES、H2-TPR、BET等表征手段对Ni/HZSM-5催化剂的形态和结构进行了表征.
