Re: [Biofuel] Biodiesel "New Process"

2007-04-20 Thread Thomas Kelly
Joe,
  In US (elsewhere?) ethanol must be rendered unfit for consumption.
 For example: Add 2 gal of unleaded gasoline to 100 gal of ethanol.
Gasoline may make the ethanol unfit for making biodiesel.
It could be denatured with methanol which would be good for making 
biodiesel, but not so good for use in cars.
 The question is: Will there be enough demand for fuel grade ethanol 
denatured with methanol?

The list of references we do have hasn't been updated for years 
because there's nothing new to add, it was "just around the corner" 
then and it's still "just around the corner" (like biodiesel from 
algae). Unless you want to use the old "Fuel From Sawdust" method 
with concentrated sulphuric acid:

Fuel From Sawdust

http://journeytoforever.org/ethanol_link.html#cellulose
Ethanol from cellulose

I suppose ARS is one of the best sources for research:
http://www.ars.usda.gov/is/search.htm
ARS : News & Events ARS News

Search for "ethanol +cellulose" (without the quotes).

Eg.:

But I don't think that's of much interest to small-scale producers. I
don't think it's easy to sell small-scale production of glycerin,
even if it's refined, so this is really only a concern for
large-scale producers.

Tom said previously the cost of phosphoric acid for separating the
by-product was covered by the recovered methanol, and you end up with
crude glycerin that accelerates a compost pile or improves production
of an anaerobic digester. Good enough I think.



>The project has  merit surely , but have  very  poor content as they

That might be the reason, or they might just be fishing for financial
support and don't really have anything much except some preliminary
results, the claims they make could be true or could be just theory,
or a mix of the two.

I think we should probably be sceptical. We've seen so many things
like this, and so few of them ever emerge into practice. I doubt this
process will contribute much to a sustainable green future.

Re: [Biofuel] Biodiesel "New Process"

2007-04-14 Thread Pagandai Pannirselvam

Hi, Keith, Ken and Tom

   Tom there is no for your apology, as we can have different views.

We, Acadamics , engineers , researchers  need to learn a lot from all the
people like
Keith and  Tom who are very practical  always work very  near to the process
problems.
What always happens to all the new and old engineers  who are good in
process synthesis , but   lack always
and also  very bad in critical analysis of the project with regard to
materials used, the complexity and viability.
Thus several millions money spent by university research  are all going as a
waste such as supercritical extraction for BiD good results at laboratory ,
but no use for largescale use.
The combination of practical and concepts based on the theory need to go
together in this list to evolve a better catalysts, prcoessos, equipments,
process seperations.

The reactive distillation means  doing  the  reaction together with the
distillation and I agree with Keith that, yet this
can be only research level.

  After Keith explanation about mixing by recirculation is an effective
way to  reduce the product revers reaction of glycerol , moreover , the
sediment ion  of glycerol , made possible means a better  way to filter out
the glycerol , thus preventing unwanted byproducts.

 Thus understanding of the process is vital to operate the plant.


At the beginning mixing can favour the reaction , the can be slow so that
the  product can be pulled out of reaction.


I also agree with Keith , there is no point to bother about glycerol
recovery as this can be easily used as liquid soap , sold soap , combustible
, , for bio gas production , even as the source for rural wood energy  and
hence  the high cost of recovery to get ultra purity glycerol is out of
question as far as the small scale process are concerned.


Yet  I have one  one question to Keith regarding the use of Methanol
instead of ethanol.

Will this two stage process can be possible with ethanol only or the mixture
of  methanol and ethanol can be possible as methanol is not ready avaialable
in several developing countries.

let us again wish others do participate actively in our list, as  this list
used to be very dynamic , let us come back all again to make this as leading
one .

Kind regards to all

It looks like an unholy marriage of the acid-base process and the
famous "supercritical methanol" process (Saka et al) that was getting
everyone excited a few years back - methanol at 5080 PSI and
350-400C. Um, no thankyou, I don't want big business doing that
anywhere near me, let alone backyarders. High temperature + high
pressure + lots of methanol as with this "new" process is likely to
kill someone, I fear.

 Agreed  as long as there is excess methanol (20% vol/vol). If it 
was possible to remove glycerin without removing methanol and caustic, less 
methanol would be required; maybe shorter reaction time.
 I'm simply struggling with the idea that reactive distillation and 
"filtration" can provide advantages to homebrewers. How do we separate "good 
grade glycerol" using temperatures that are safe? I don't know much about 
reactive distillation, and maybe the process referred to as "filtration" is 
different from what I have in mind. I would like to hear more from anyone 
with knowledge about reactive distillation as it would apply to biodiesel 
production and what is involved in the process referred to as "filtration".
   Best to All,
 Tom

Our 90-litre processor allows a good proportion (maybe half) of the
by-product to drop out and settle, with another proportion of it
being recirculated much more slowly than the rest of what's being
processed, which keeps that much methanol in action, and the GC tests
showed 99+% ester content.

See:
http://journeytoforever.org/biodiesel_processor10.html#settle

Recirculation is fast in this processor. I add the first-stage
methanol (slowly) and let it mix thoroughly with the WVO, which makes
it look like milky coffee, and then I pour in 60ml of sulphuric acid
at the top, which turns it chalky, and the colour change happens in
about one second. So it mixes efficiently, but at the same time lots
of by-product drops out as it's being formed.

Simple processors that don't seem to allow for this can nonetheless
get high-quality results even with single-stage base. So I don't
think the reverse reaction from glycerin formation can be that much
of a constraint. I can't see a need for multiple or any filtration
steps or centrifuging or whatever to remove glycerin.

 I understand that removing the glycerol will "pull" the reaction towards 
ester formation. Is there a way to remove the glycerol and "diverse di glcerol 
byproducts" (by "filtration") as they form without also removing methanol and 
caustic? Does "filtering" refer to something different from simply draining the 
glycerine layer?

It looks like an unholy marriage of the acid-base process and the 
famous "supercritical methanol" process (Saka et al) that was getting 
everyone excited a few years back - methanol at 5080 PSI and 
350-400C. Um, no thankyou, I don't want big business doing that 
anywhere near me, let alone backyarders. High temperature + high 
pressure + lots of methanol as with this "new" process is likely to 
kill someone, I fear.

But I don't think that's of much interest to small-scale producers. I 
don't think it's easy to sell small-scale production of glycerin, 
even if it's refined, so this is really only a concern for 
large-scale producers.

Tom said previously the cost of phosphoric acid for separating the 
by-product was covered by the recovered methanol, and you end up with 
crude glycerin that accelerates a compost pile or improves production 
of an anaerobic digester. Good enough I think.



>The project has  merit surely , but have  very  poor content as they 
>do not wish to share the technical information.

That might be the reason, or they might just be fishing for financial 
support and don't really have anything much except some preliminary 
results, the claims they make could be true or could be just theory, 
or a mix of the two.

I think we should probably be sceptical. We've seen so many things 
like this, and so few of them ever emerge into practice. I doubt this 
process will contribute much to a sustainable green future.

Robert said something similar recently. It has been quieter than

Dear Thomas, Ken, Trevon and everyone:

I think it is safe to say that we are all in agreement that there's nothing
in the process that we don't already know. 

The last "new" thing I found about biodiesel production was sulfonated
charcoal as catalyst. I made some and got some decent reaction but the
process of making the stuff was a complete turn-off.

If you guys do find something new do share.Thanks.

Best,
Chris

 My apologies to the authors of the study. My criticisms  "Sounds like a 
poorly written science project" and "it doesn't seem to make any sense" 
sprouted from my own ignorance. 
 I am doing my homework on the subject of reactive distillation.  

 I must admit to a bias that may compromise my acceptance of any "new 
process." I like the idea of being able to make what I believe to be high 
quality biodiesel, myself, on my own spot of land, using little more than what 
I can scavenge from my local scrap metal dump. A new process that goes beyond 
the reach of an average "Tom" and puts control back into the hands of big 
business may be new, but not necessarily better. As you said:

Looks like he is using high heat and pressure as the
aid in the process and apparently a lot of methanol.
This doesn't look like a homebrewer's use but someone
with a controlled lab might be able to do it.  And
possibly someone who has a little more money.

Hi,

I guess using high temperature and pressure can push
the reaction to completion but it did not say how high
a temperature and pressure.  It would be dangerous for
backyarders like myself to tinker with such extreme
conditions without proper facilities and equipment. 
Maybe thats why the "founders" of biodiesel used the
process today.  Simple, easy and safer.

Though i'm open to try other stuff, some guidance is
very much appreciated starting with what temperature
and pressures are we talking about.

Best Regards to everyone.
