How to produce bioethanol?

[Rabbit]

The system is ingenious but has to pour what it produces
from the tank, there is still a margin.

But it's already a good start if you don't ride too much.

Guide to go illegal!
Sugar beet is essential because it corresponds to the season and fermentation takes place quickly and without much problem because its share of sugar is very high.
Finally, before the principal was said but I do not practice the same dosages as those given before for water and yeast.
Beware of aches after having grated the beets which are very hard and patience, it is a good action accomplished and a kind of bodybuilding exercise!

Otherwise, I forgot!
On the partner of our forum, I found a lot of information there and we can ask any questions we want.

What proportions of water do you recommend?

When I did the experiment I used 3 sachets of yeast
Porto. I have it on hand because I sometimes do
wine of Cassis .

As far as I am concerned, I must say that the beetroot
it smells strong. Even that it is difficult to bear.

it is certain that this production this preparation is far from being any comfort ... or even any rest but I really think that it is worth it.
I put less water, about 800ml per kilo but it is the recipe that I had given me, after, I do not know if putting a liter improves or decreases the quality of the final result

Hello !!

I just wanted to ask a question, not in relation to the experience as such but to a document that we found about bioethanol. This is a diagram showing the different ways of achieving bioethanol. However, in the part corresponding to "sweet plants", only the "extraction" part is entered before fermentation, no hydrolysis. However, we carried out an experiment with beterave and carried out a hydrolysis ... On the other hand, for "starchy" plants and lignucellulosic matter only hydrolysis (with pretreatment for the latter) is indicated before fermentation. : hum:

Finally, we don't see where our error is, except maybe in the document, since we needed to do a hydrolysis with our beet ... So if you could clarify us a little ...

I read the way you describe the extraction of sugar, but we did it completely differently Oo: we peeled / cocettes the beets, then acidified the medium with hydrochloric acid of high concentration to finally neutralize it with soda .... um not quite what you say ... I guess the cause is that there are several exploitable protocols (at least I hope !! History that we do not have all missed !!)

Nice indeed the plastic still.

but indeed, such a simple distillation is not enough to obtain an alcohol usable at 90-95%. Several successive distillallations are necessary in fairly tall columns.

It is entirely possible to distill with solar energy by passing the water coming from the collector through a coil immersed in the must, regulation may nevertheless be necessary

as far as the law is concerned, the industries are supervised by excise employees who constantly check the proportion between the incoming raw materials and the quantities produced.
Material yields are known and can be cross-checked, eg; by also checking energy consumption.
The alcohol produced is then denatured, e.g. eg with methanol or ether to make it unfit for consumption

I am surprised that you bring this subject to the surface since the
beet season is more than completed, as is beet
who survived the winter must be stunted and more than
low in sugar.
Either way, sugar beets contain sucrose
and that’s what makes them interesting.
rapping them and adding yeast and water.
The ideal being obviously to extract the sugar before fermentation.

In addition it is not all about producing alcohol, it is also necessary
purifying it which is no small matter (energetically
speaking) .Especially when we aim for 95 -99%.

Hello
I read the different comments and I was wondering
is there a simple way for an individual to make a usable fuel directly from beet.
Indeed from what I read to ferment it ok but after?
Anyone among you doing it? and is it driving with a vehicle running at 100% with this distillation?
Thank you for your direct and concrete answers
