Wiki page for members bio oxidisation tests

[Julian]

Thought Id' start a new thread to hopefully start this idea of using the wiki to collate collaborative tests done by members and detail experimental processes they may be trying.

This idea originated from this thread ... http://www.biopowered.co.uk/forum/index.php/topic,2518.15/topicseen.html

Page is here ... http://www.biopowered.co.uk/wiki/Biodiesel_and_oil_oxidisation_collaborative_trial


I've started filling in the table and will complete it tomorrow once I've set some bio aside in a saucer.

I really hope others will join in.

Can any one suggest the frequency needed between observations?

Welcome any comments good or bad!

Does Weekly sound good?

[Julian]

We can try that but I was thinking we may need to look at months.

I'll make it weekly and we can see how it goes.

I will put some by. Are you using bio after settling or straight from the processor?

[Julian]

Nick may have a better idea than me ... it was his idea, but I'd suggest people use whatever they consider their finished bio.

Perhaps brief notes as t the production methods and type of washing if any would be helpful ... I'll add to the wiki page.

We know that certain metals promote oxidation, copper in particular and iron to a lesser extent. I think it would be interesting to include some samples that contain copper fillings or iron fillings. This would better simulate conditions in our fuel system that have many metal parts.

Sounds like an idea.  It might be easier for people to obtain small scraps rather than filings although the surface area wouldn't be as great.  Feel free to modify the page to include this or would;d you like me to do it?

Just updated the wiki page with a photo of my efforts plus some text.

Great start Julian. I think we could also investigate feedstock as it looks like iodine value is a factor. I think all my oil these day is GM Soya but it would be  good to include palm oil and rapeseed (& sunflower?) in the trials. Palm oil has the lowest iodine value and so I think we would expect this to be less susceptible to oxidation.

[Julian]

Yes, it may be a good start but it's a little futile if I'm the only one participating!

I have three jars on the go - one plain bio, one with copper wire and one with iron wire. Nothing to report so far.

[Julian]

I was going to use beakers, but thought that may effect the level of oxygen at the surface ... I believe nitrogen is slightly heavier than oxygen.  Don't know it that makes any sense but that was my Muppet level reasoning?

Similarly having the samples outside I thought might allow better air movement over the surface.

Copper sample is already showing signs of "green" around the wire.

Just added comments for the last two weeks.

Nick you deleted a post.  I agreed with what you said about the science, but I think exercises like this are valuable in the future if lots of people get involved.

Yes, I wrote it last night when I was wound up (don't ask) and dog tired. After sleeping on it, I thought it was unduly critical so I removed it. I fully agree, what we're doing is a useful exercise and should hopefully give us some ideas for future, more scientific testing

Cheers
