Biofuels are used for transportation sector but not good for electricity
generation or burning. Biomass may be the sole sustainable primary energy
source for transportation sector. So it is why it is important to develop
better biofuels. (Note: transportation fuels accounts for ~20 % of the total
energy market based on BTU. In the USA, it is about ~30% of total market).
Biofuels R&D is like dotcom. Most researches are trash, including famous

做一些QA, Process design, analysis,hse ,这些比较适合女孩子的工程工作。 |

► Cellulosic ethanol and butanol are the best short- and middle-term
biofuels.
► Sugary hydrogen would be the best ultimate biofuel.

y********a 发帖数: 77 | 9 It depends on whether energy crop can be successfully produced in large area
or not. And the definition of biomass could be broader.
Your concern is reasonable, that's why this kind of work is mainly in the
lab orpilot scale now. However, many other researches have the same
situation before they were fully commercialized. The technical breakthoughs
are needed in this area. But is this different with others?

s*********e 发帖数: 68 | 31 That's why they pay more attention to "biomass energy".
According to USDA, they've planned to develop more "cellulose ethanol"
instead of "corn ethanol". There are bunch of arguments. A famous representative is from Cornell University, but they actually
doubt if bio-ethanol is environmental friendly. Then other people jump out
to prove bio-ethanol is environmental friendly. Many debates on if food
price is driven by the ethanol plant. Someone said yes it is. Then there are
reports said no,ethano |

S*****n 发帖数: 6055 | 41 biodiesel就是概念提出的比较早,被很多地方用来作秀,其实没啥前途
biofuel要真想做大规模应用,还得在lignocellulose上下功夫
发酵也好,热解也好,只有lignocellulose才有足够的产量能够在energy market上占
据一定的share |

u***n 发帖数: 1263 | 42 关键是lignocellulose不能直接吃
所以好啊 |

S*****n 发帖数: 6055 | 43 bio-oil的产量比lignocellulose至少小一个数量级,也有可能是两个,我记不清楚了 |
|
u***n 发帖数: 1263 | 44 现在大部分的lignocellulose都烧了,发电了 |
|
S*****n 发帖数: 6055 | 45 关键是如何弥补transportation fuel的缺口?
是把lignocellulose用来发电,省出煤来做煤液化?
还是继续用煤发电,研究lignocellulose to transportation fuel?
而且其实lignocellulose和煤转化成transportation fuel的途径多少有些类似。。。
当然,每个人都有自己的看法 |
