Abstract:
PURPOSE: A method for extracting butyric acid from fermented liquid and chemically converting the butyric acid to a bio fuel is provided to produce butyl butyrate as the bio fuel. CONSTITUTION: A method for producing bio fuel from fermented butyric acid comprises: a step of providing fermentation liquid containing butyric acid through fermentation of carbohydrate to liquid extracting tower; a step of using trialkylamine as extraction solvent to produce the butyric acid in the form of trialkylammonium butyrate; a step of adding the extracted trialkylammonium butyrate to isolate butyric acid and trialkylamine; a step of supplying trialkyl amine to the liquid extracting tower as a extraction solvent; and a step of reacting the butyric acid with butanol to convert to butyl butylate.
Abstract:
A method for preparing bio-butanol is provided to prevent the deterioration of the activity of microorganism and to improve the productivity and economical efficiency of bio-butanol. A method for preparing bio-butanol comprises the steps of pulverizing, washing and hydrolyzing the biomass or the organic waste; inoculating Clostridium bacteria to the obtained carbon source and culturing it by anaerobic culture to collect the culture solution containing butyric acid and a hydrogen gas; adding butanol in a mole identical to that of butyric acid to the culture solution; adding a strongly acidic catalyst such as zeolite, heteropoly acid, silica-alumina, Nafion resin, p-toluenesulfonic acid. SO4^2-/ZrO2 or SO4^2-/TiO2-La2O3 to convert the butyric acid and butanol of the culture solution into butyl butyrate; and reacting the butyl butyrate with the collected hydrogen by using a catalyst of (CuO)a(ZnO)b(CoO)c(FeO)d(YO)e to produce butanol, wherein a is 0.1-80, b is 0.1-60, c is 0.1-80, d is 0.1-20, e is 0-5, and Y is W, Pd, Pt, Ru, Cs, Ma, Ca or Ba.
Abstract:
본명세서에는이산화탄소로부터말라리아치료전구물질인아모파디엔을생산할수 있는형질전환된시네코코커스일롱게투스균주가개시된다. 상기균주는이산화탄소를탄소원으로사용하여아르테미시닌의전구체인아모파디엔을대량생산할수 있다. 또한, 상기균주는, 빛과대기중에존재하는이산화탄소를탄소원으로사용하여고가의아르테미시닌의전구체인아모파디엔을생산하기때문에경제적이며, 미생물을사용하여, 대기중의이산화탄소를제거또는저감하는데활용될수 있으므로, 친환경적이다. 또한, 균주배양에기후의영향을받지않기때문에안정적으로아모파디엔을생산할수 있는이점이있다.
