中文摘要：
采用化学还原法制备了Ni—B和Ni-Co—B非晶态催化剂，并采用X射线衍射（XRD）、BET比表面积、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和电感耦合等离子体光谱（ICP）进行了结构表征．结果表明，在110℃及氢冷压4．0MPa时，在Ni—B或Ni—Co—B催化下，丙酮、糠醛和苯酚的转化率和饱和醇的选择性分别达到99．99％和95．00％以上．对于Ni—B催化生物油真实体系，在150℃及氢冷压4．0MPa下，饱和醇的收率达到47．54％．温度过高易导致催化剂转晶从而降低反应活性．为生物油的有效利用和饱和多元醇的制备提供了新思路．
英文摘要：
Ni-B amorphous catalysts were prepared by chemical reduction of nickel chloride with potassium borohydride aqueous solution and characterized by X-ray diffraction（ XRD）, Brunauer-Emmett-Tetter（ BET）, scanning electron microscopy （ SEM）, transmission electron microscopy （ TEM）, inductively coupled plasma （ICP） techniques. The catalytic performances of model compounds and bio-oil to produce saturated alcohols were evaluated in a semi-batch reactor. The results showed that the conversion of model compounds （ acetone, furfural and phenol） and the selectivity of saturated alcohols reached 99. 99% and 90. 00% at 110 ℃ , 4. 0 MPa（initial pressure）. Under the conditions of 150 ℃ and 4. 0 MPa, the yield of saturated alcohols reached 47.54%. High temperature of above 150 ℃ resulted in the transformation of amorphous phase to form crystal, which was attributed to the low catalytic activity. This work provides a new alternative for the production of saturated alcohols from bio-oil.
