摘要：文章研究了不同加氢催化剂对富酚的模拟生物油轻质组分与甲醇加氢共裂化制备芳香烃过程的影响。研究结果表明,酚类在加氢阶段的加氢效率与整体的加氢共裂化表现呈现出一致性;以Ni/ZrO2为催化剂时,酚类在加氢阶段的转化率最高,加氢共裂化的油相产率也最高,为24.8%,且油相中芳香烃的相对含量在99%以上;其他加氢催化剂对酚类的转化效率相对较低,较多酚类的存在导致裂化阶段的催化剂快速失活,加氢共裂化的油相产率明显降低。
This article studies the effects of different hydrogenation catalysts on the production of aromatic hydrocarbons from co-cracking of phenol-rich simulated bio-oil light fraction and methanol.The results show that the hydrogenation efficiency of phenols in the hydrogenation stage is consistent with the overall hydrogenation co-cracking process;when Ni/ZrO2 is used as the catalyst,the conversion rate of phenols in the hydrogenation stage is the highest,while the oil phase yield in the hydrogenation-cocracking stage is also the highest,which is 24.8%,and the relative content of aromatic hydrocarbons in the oil phase is above 99%;the conversion efficiency of other hydrogenation catalysts to phenols is relatively low,and the presence of more phenols leads to the rapidly deactivated of catalysts in the cracking stage,while the yield of the hydrocracked oil phase is significantly reduced.
