Celanese Corporation, developer of a hydrocarbons - to -
ethanol production process derived from its acetyl technology (earlier post) announced plans in June to enter the industrial ethanol market in China by revamping the market entry strategy to allow the company to enter 6 - 12 months sooner than originally planned.
When we assume
the ethanol production process is fully renewable, it would take all the corn in the country to displace about 3.5 percent of our gasoline consumption — only slightly more than we could displace by making sure drivers» tires are inflated properly.
Not exact matches
And Brazil, arguably the world leader in making
ethanol from crops, has been turning sugar cane into fuel for nearly three decades — a
process that is 30 % cheaper than corn - based
production in the U.S.
Using Patzek's methodology for every aspect of
ethanol production save the conversion
process itself, a gallon of Corn Plus
ethanol consumes less energy than it contains — even before factoring in credit for coproducts.
In another experiment, bagasse was used as a starting plant biomass for
ethanol production without washing / separation
processes.
The cellulosic
ethanol process we developed was unique because it did not require multiple
processing steps and the use of expensive laboratory - modified enzymes, the
ethanol bioprocessing system uses significantly less water and energy in
ethanol production resulting in larger yields per ton of biomass.
At a biofuels energy symposium hosted by the Institute of Medicine of the National Academies last week in Washington, D.C., professor Jerald Schnoor said corn
ethanol production facilities require large quantities of high - purity water during the fermentation
process.
The new yeasts accelerate the wort fermentation
process and improve the
production of
ethanol.
AE Biofuels uses an enzyme - based approach to the
production of cellulosic
ethanol and has designed our
process to be integrated with existing corn
ethanol production, in addition to building cellulose - only plants.
«(i) is in one of the following industrial sectors:
ethanol production; ferroalloy
production; fluorinated gas
production; food
processing; glass
production; hydrogen
production; iron and steel
production; lead
production; pulp and paper manufacturing; and zinc
production; and
The two scientists calculated all the fuel inputs for
ethanol production — from the diesel fuel for the tractor planting the corn, to the fertilizer put in the field, to the energy needed at the
processing plant — and found that
ethanol is a net energy - loser.
However, the
ethanol concentration yielded from a cellulosic
ethanol process tends to be significantly lower than the concentration obtained in a conventional
ethanol production.
Q Microbe ™ converts a wide array of cellulosic biomass directly into
ethanol in a single step, consolidating enzymatic hydrolysis and fermentation, largely eliminating costly enzymes and associated pretreatment, and simplifying the entire
production process.
The
production and use of
ethanol merely recycles in a different way the CO2 that has been fixed by plants in the photosynthesis
process.
It does not release carbon that would otherwise stay stored underground, as occurs with fossil fuel use, but when starch, such as corn, is used for
ethanol production much energy, including fossil - fuel energy, is consumed in the
process of fertilizing, plowing, and harvesting.

Wayne Hoovestol, Chief Executive Officer said: «Algae is potentially a by - product of
ethanol that makes the
process cleaner and greener through carbon sequestration... Algae
production fits into Green Plains» business model since we are already in the business of marketing biofuel and feed products.»
So, researches are hard - at - work to uncover different methods to separate these tough structures in order extract the sugars needed for the
process of
ethanol production.
Since cellulosic
ethanol is created by using all of the parts of the plant being used (instead of the 10 %, mainly the edible part, of the plant), in all likelihood, if this
process turns out to work as advertised, we could use the discarded parts of corn, or non-edible plants such as switchgrass, so food
production would not have to be drastically increased.
To get the whole picture you have to consider
ethanol's entire life cycle — the energy inputs and global warming pollution arising from every step in the
production process, such as:
