传统上，生物丁醇是用ABE（丙酮丁醇乙醇）工艺生产的，该工艺使用梭菌属物种从生物质中发酵糖。然而，该路线与一些缺点相关，例如丁醇产率低和副产物（丙酮和乙醇）形成。另一方面，丁醇可以通过金属氧化物/羟基磷灰石催化剂上的羟醛缩合由乙醇直接制备。本文认为化学转化路线比ABE工艺更优选，因为与发酵路线相比，反应进行得更快，并且获得产物所需的步骤更少。
Traditionally, bio-butanol is produced with the ABE (Acetone Butanol Ethanol) process using Clostridium species to ferment sugars from biomass. However, the route is associated with some disadvantages such as low butanol yield and by-product formation (acetone and ethanol). On the other hand, butanol can be directly produced from ethanol through aldol condensation over metal oxides/ hydroxyapatite catalysts. This paper suggests that the chemical conversion route is more preferable than the ABE process, because the reaction proceeds more quickly compared to the fermentation route and fewer steps are required to get to the product.
