| titleOfInvention | Method for fermentation and differential pressure distillation of butanol by stalk dilute acid hydrolyzate |
| abstract | The invention relates to a method for the fermentation and differential pressure distillation of butanol by stalk dilute acid hydrolyzate, which comprises the following steps of: with the stalk dilute acid hydrolyzate as a carbon source and corn extract and starch milk as nutrient substances, fermenting by utilizing Clostridium.acetobutylicum to obtain 1.8-2.3 percent of total solvent; and leading fermented mash to pass through a positive pressure tower and a negative pressure tower for carrying out rough distillation and obtaining 45-55 percent of total solvent at the tower top. The invention produces the butanol by fermenting cheap stalks and reduces the cost of raw materials; the differential pressure distillation is adopted in the rough distillation process of a fermenting liquid, the consumption of steam only accounts for 50 percent of that of the traditional rough distillation tower, the production energy consumption of solvent separation is reduced, and the method has favorable economic benefits. |
