Lignocellulose pretreated with dilute alkali and hydrolysed with cellulases was used as substrate for the processing of acetone–butanol–ethanol (ABE) clostridial fermentation followed by the vapour-phase membrane concentration of two alcohols and acetone with up to 99% degree of recovery. ABE concentrate was used for the catalytic synthesis of fuel components over a zeolite catalyst with aliphatic and aromatic hydrocarbons as the main products with up to 60% conversion. The zeolite catalyst was effectively regenerated from coking by hot steam treatment with up to 100% recovery in catalytic activity. The main novelties of the process are in demonstration the effectiveness of vapor-phase ABE concentration, its effective conversion to hydrocarbons followed by of catalyst’ regeneration. The process described paves the way to developing renewable technologies for the production of motor fuel components.

用稀碱预处理并用纤维素酶水解的木质纤维素被用作丙酮-丁醇-乙醇（ABE）梭菌发酵的处理底物，然后是两种醇和丙酮的汽相膜浓缩，回收率高达99％。ABE浓缩物用于在沸石催化剂上催化合成燃料成分，脂肪族和芳香族烃为主要产物，转化率高达60％。通过热蒸汽处理从焦化中有效地再生了沸石催化剂，催化活性的回收率高达100％。该方法的主要新颖之处在于证明了气相ABE浓缩的有效性，其有效转化为碳氢化合物以及随后的催化剂再生的有效性。
