载体和反应条件对生物油模型分子苯酚的加氢去氧性能影响
The Effects of Catalyst Carrier and Reaction Conditions on the Hydrogenation Deoxidation of Bio-Oil Model Compound Phenol
摘要: 采用活性炭(AC)、碳纳米管(CNT)、石墨烯(RGO)和类石墨相氮化碳(g-C3N4)为载体制备Pd负载型催化剂,我们研究了载体和反应条件对生物油的催化加氢去氧性能(HDO)的影响。通过制备Pd负载型催化剂,分别实验探讨了4类载体对HDO反应的影响规律。结果表明:当活性炭和碳纳米管作为载体时,在反应温度达到150℃~180℃时才表现出较好活性,并且对加氢产物环已醇和环已烷的选择性相差不大,表明这2种载体与Pd的协同效应有限;而石墨烯和类石墨烯氮化碳为载体时,在90℃~110℃范围内即展现良好活性,且对加氢产物环已烷的选择性明显高于环已醇,尤其是Pd/g-C3N4的选择性达到85.4%,表明其与Pd的协同效应最好。
Abstract: Activated carbon (AC), carbon nanotube (CNT), graphene (RGO) and graphite-like carbon nitride (g-C3N4) were used as carriers to prepare Pd supported catalysts. The influence of carriers and re-action conditions on HDO reaction was investigated by us through experiments. By preparation of Pd-supported catalysts, we investigated the effects of four kinds of carriers on HDO reaction ex-perimentally. The results showed that the activity of AC and CNT was reflected when the reaction temperature reached 150 - 180 degrees, and the selectivity of the cyclohexanol and cyclohexane was not significantly different, indicating that the synergistic effect between the two carriers and Pd was limited. However, when graphene and graphene-like carbon nitride were used as carriers, they exhibited good activity within the range of 90 - 110 degrees, and the selectivity of cyclohexane was significantly higher than that of cyclohexanol, especially the selectivity of Pd/C3N4 reached 85.4%, indicating the best synergistic effect with Pd.
