Abstract:
Autothermal steam reforming (ATR) of bio-oil, which couples the endothermic steam reform-ing reaction with the exothermic partial oxidation, offers many advantages from a technical and economic point of view. Effective production of hydrogen through ATR of bio-oil was performed at lower temperature with NiCuZnAl catalyst. The highest hydrogen yield from bio-oil reached 64.3% with a nearly complete bio-oil conversion at 600 oC, the ratio of steam to carbon fed (S/C) of 3 and the oxygen to carbon ratio (O/C) of 0.34. The reaction con-ditions in ATR including temperature, O/C, S/C and weight hourly space velocity can be used to control both hydrogen yield and products distribution. The comparison between the ATR and common steam reforming of bio-oil was studied. The mechanism of the ATR of bio-oil was also discussed.

摘要:
在较低的温度下,通过将放热的部分氧化反应和吸热的水蒸汽重整反应耦合起来的自热方式实现了高效的制氢过程. 在氧碳比(O/C)为0.34,水碳比(S/C)为3,温度为600 oC时生物油接近完全转化,得到最高氢产率为64.3%. 自热水蒸汽重整反应条件温度、O/C、S/C、质量空速等可以用来控制反应氢产率和气体产物分布. 对自热过程和普通水蒸汽重整过程做了比较,并对反应机理进行了探讨.
