FYI, We have significant experience with Eco2pure and I state the following as confirmed fact. #1 it is nothing more than oak as a byproduct of furniture manufacture with the aforementioned molecular sieves inconsistently mixed, i.e. settled out mostly at the bottom of the barrel or bag.It acts as both an adsorbent and oak contains tanic acid which breaks the soaps. #2 It can and will auto ignite, we just had the last spent load from 3 towers catch fire after 12 hours, our chemist says this is caused by oxidation in relation to hydrogen peroxide. #3 It does not last anywhere near as long as it is purported to. We have a very comprehensive commercial processor with methanol recovery and centrifugal glycerin removal and know for a fact we are delivering first rate FAME to the tower, at 410 to 500 PPM soap the best throughput we have achieved is 15,000 liters for 3 towers holding 120 kilos of media. At 1600 to 1800 PPM soap we have never gotten better than 6000 liters through before soap exceeds ASTM specs.To get our soap from 1600/1800 to 500/600 we started water washing to see what kind of life we would get out of it. We were told that at 1800 ppm we should get the advertised low end thru put of 131 gallons per kilo. For those of you who don't care if your fuel has soap in excess of allowable numbers you will inevitably damage your injectors (coking) and or get carbon residue in the cylinders. I know I have run **** fuel in my 05 sprinter and paid the price. Gospel truth.

Yep. That sounds about right...

I know this guy went through his Eco2Pure really fast...

Interesting about it auto-igniting.
Makes sense though.

Maybe they can pack up spent Eco2Pure and sell it as auto igniting logs.

KTM,

We have also not seen the Eco2Pure live up to its advertised ability to "purify" crude biodiesel. I have posted more realistic numbers in previous post and more realistic cost per gallon of production.

Having said this we do see it as a great knock down filter media or in other words: if you do a lot of methanol removal (demethylation) from your biodiesel prior to processing with the macroporous resin then soap rapidly starts to coagulate and this slime can then be knocked out by the wood chips.

This saves the resin from getting wasted yet allows the biodiesel producer to rapidly go from methanol removal to very good fuel...

Lastly we have also observed the molecular sieves settle out however if the saw dust ratio to "chippy" content is kept at the correct ratio the saw dust tends to hold the molecular sieves more consistently.

On these batches of Eco2Pure we have seen a fairly consistent 60/40 split by weight...
