虽然生物乙醇做的人很多,但是通过对ABE发酵过程的改造,丁醇的收率提高占总能量25%左右,如果加上发酵过程中产生的氢气占18%左右,发酵丁醇所得到的产品的能量将比乙醇高20%左右,况且跟乙醇比丁醇有很多优点。
最简单的是丁醇的价格是乙醇的三倍。
但是丁醇受到的重视不够,尤其是跟乙醇相比。
DuPont’s vision for biobutanol is based the following superior fuel characteristics over bioethanol :
• Can be handled in the existing distribution infrastructure without requiring modifications in blending facilities, storage tanks or retail station gas pumps.
• Is expected to be suitable for transportation in pipe lines.
• Can easily be added to conventional gasoline at all ratios and its energy content is closer to gasoline than ethanol .
• Is well suited for current vehicles and engine technologies.
• Will not force automakers to compromise on performance in order to meet environmental regulations.
