I've finally got round to sticking the samples in the freezer.  Not a scientific test at all as it's just one batch and not chilled in increments as I did for the HMPE water washing tests and there are no control samples.

BUT, the samples have been sitting for three days at -18°C and are still at least 50% liquid!  I have to say that's the best cold weather fuel I've produced.



Sample on the right is straight bio,  The one on the left has Cold Flow added.

They are thawing as I post ... I'll report any sediments (possible HMPEs) if they occur, but in my opinion the bio should be chilled slowly over a long period to be a fair test.

Hi Julian
I can't see the pick's but will take your word for the quality of winter bio.
To make things easer to mix I'm getting some anhydrouse powdered sulphuric acid in January so will see how it mixes with meth and if it goes well I will send some out for trials.

Are you saying the one on the right which is more bio and less whites is the non treated fuel ?

Strange you can't see the photo, try this link  http://www.palmergroup.co.uk/Bio/Methacid%20samples.JPG 

The powdered sulphuric sound interesting, but if it's equally as strong, won't it behave in the same way?

To make any tests meaningful, we really need samples from several people along with controls.  If we can achieve that, I'll buy a controller for the freezer and replicate the chilling tests.  I think it would be a good idea to try and run tests on your titrated acid wash too.  Far more people are using that method and I'm sure most wouldn't mind mailing a sample or two.

The samples have thawed now.  The non treated sample is clear with no apparent drop out.  The Cold Flow sample has a very small amount of precipitate, but it went cloudy when treated.  So I'm guessing the freezing has some how made the cloudiness drop out.

Yup.  I think the photo might be a bit misleading, when they came out of the freezer, they looked pretty similar.  The treated bio was slightly clearer when frozen (it wasn't at ambient).

For the first couple of days the wax dropout would move quite freely when the jars were tilted.  I think they may have compacted slightly as they were fairly solid today.

Carrington is probably using a mobile device. Julian's hosting breaks images for mobile devices. His avatar doesn't show either on my mobile for the same reason.

Hi Julian
If I get the powder mixes well with the meth which I realy believe it will then I will see who wants to do the trials and send out the powder so we are all working with the same product , this should give us more accurate results and also make the procedure more straight forward in the future for all.
Still can't see the picks but in my head the one with the cold flow looks a bit grim and the one processed in the new crazy way looks fab (but I could be wrong).

I should take delivery of the powdered sulphuric on jan 4th so will get on it ASAP

Paul

Yes on mobile so this is why I'm not able to see picks

Am I right in seeing that the pot with the coldflow, has got almost twice as much lard in the bottom as the pot without the coldflow???

Thanks, Tony.  Not sure what "breaking images" is but is there anything I can do to change that in my hosting control panel?

Cheers Julian just got the mail
So if I get this right the one on the left which looks to have more whites is the one with cold flow , but  they where taken out from the freezer they both where about the same.
If this is right then maybe -18 is just to cold for both but as they warm the the untreated is returning to normal at a lower temp. Can I give you a ring tomorrow just so I can get things straight in my head

Yes, no problem, but like I said I think the photo's misleading ... I had been tipping the jars to see how solid the wax was.  I was more impressed with the clear bio above!

I'll put them back in the freezer for a couple of days and take more care with the photo.

A big thanks for another great thread!  That's what we're interested in, pushing the boundaries of what we currently think we know.

Not my idea ... Paul (Carrington) should take any credit, I just followed instructions and, after a quick change of skiddies, wrote it up.

We really need more samples and controls to determin if there's any merit in the process.
