For production of biodiesel from bio oils by heterogeneous catalysis, high performance catalysts of transesterification and the further utilization of glycerol have been the two points of research. The process seemed easy, however, has never been well established. Here we report a novel design of catalytic distillation using hierachically integrated CNTs-based holistic catalyst to figure out the two points in one process, which shows high performance both for the conversion of bio oils to biodiesel and, unexpectedly, for the conversion of glycerol to more valuable chemicals at the same time. The method, with integration of nano, meso to macro reactor, has overwhelming advantages over common technologies using liquid acids or bases to catalyze the reactions, which suffer from the high cost of separation and unsolved utilization of glycerol.
用于生物油通过多相催化生产生物柴油的过程中，高效的酯交换催化剂和甘油的进一步利用一直是两个研究重点。该过程看似简单，但从未得到很好的建立。在这里，我们报告了一种使用分层集成 CNTs 整体催化剂的催化蒸馏的新设计，以在一个过程中解决这两个问题，该设计在将生物油转化为生物柴油方面表现出了高性能，同时也出人意料地将甘油转化为更有价值的化学品。该方法将纳米、介孔到宏观反应器集成在一起，与使用液体酸或碱催化反应的常见技术相比具有压倒性的优势，后者存在分离成本高和甘油利用问题尚未解决的问题。
