The steam reforming of bio-oil-derived acetic acid over the developed Ni/CeO-ZnO nanoparticle catalysts for hydrogen production was studied. The correlations of CeO to ZnO mass ratio (CZMR) and nickel loading with the properties and performances of Ni/CeO-ZnO catalysts were explored. The H, CO, and potential H yields followed a Gaussian normal distribution with increasing the CZMR. An exponential function equation was established to correlate the H, CO, and potential H yields with Ni loading. As the CZMR increased from 0 to 1/3, the H yield increased from 57.8 to 69.4%, with a growth rate of 20.1%. Further, on increasing the CZMR from 1/3 to 3, the H yield decreased by 37.6%. The CO yield showed a similar trend for the H yield on increasing the CZMR, which first increased to a peak value, then started to decrease rapidly and finally stabilized. The yield of H increased significantly from 20.6 to 73.5%, with the increase of nickel loading from 0 to 15%. Further, on increasing the nickel loading from 15 to 25%, the H yield increased by only 5.8%. With the CZMR of 1/3 and the nickel loading of 15%, the selectivities of H and CO were as high as 91.6 and 42.3%, respectively.
研究了在开发的用于制氢的Ni/CeO-ZnO纳米颗粒催化剂上生物油衍生的乙酸的蒸汽重整反应。探讨了CeO与ZnO质量比（CZMR）和镍负载量与Ni/CeO-ZnO催化剂性能之间的相关性。随着CZMR的增加，H、CO和潜在H产率遵循高斯正态分布。建立了指数函数方程以关联H、CO和潜在H产率与镍负载量的关系。随着CZMR从0增加到1/3，H产率从57.8%增加到69.4%，增长率为20.1%。此外，当CZMR从1/3增加到3时，H产率下降了37.6%。随着CZMR的增加，CO产率与H产率呈现相似趋势，即先增加到峰值，然后开始迅速下降，最终稳定。随着镍负载量从0增加到15%，H产率从20.6%显著增加到73.5%。此外，当镍负载量从15%增加到25%时，H产率仅增加了5.8%。在CZMR为1/3且镍负载量为15%时，H和CO的选择性分别高达91.6%和42.3%。
