Intensification of Higher Alcohols Biosynthesis - An Advanced Feedstock for Biofuel Production

At present the problem of alternatives to fossil fuel is so critical that it sets an objective to search optimal renewable feedstock for biofuel. Being an alcohol production by-product fussel oil consists of higher volatile alcohols and can become such feedstock. Fusel oil is theoretically possible to process by the alcohol to jet (AtJ) method converting it into biojet fuel. Thus, it is reasonable to intensify the higher alcohols biosynthesis to increase the efficiency of biofuel production. However, it tends to be problematic to reach higher than average 0.35% of ethanol yield of higher alcohols within industrial conditions. This paper shows the increase of up to 0.82% of ethanol under modeled industrial conditions. Also the theoretical maximum of achievable increasing of up to 3.5% of ethanol has been calculated.
