How to turn plastic waste into diesel fuel cheaply

[piccolo chimico]

ciao rozier56, il mio reattore prima di modificare riusciva a riscaldare da 20/400 gradi in 25 minuti ma troppo potente. tu che tipo di bruciatore usi? a gas o elettrico?

[piccolo chimico]

Nice proper flanges on your pyrolysis unit. Are you going to insulated the upper section? The upper section looks like it is more than reflux, but also fractionation? I look forward to hearing about your results.

ciao BB, non so se fare l' isolamento sul mio reattore perchè sto provando a togliere la pompa del vuoto quindi avrò bisogno 400 gradi nel mio reattore e di temperature più basse nel reflusso e nel frazionamento, quindi ci siamo o lo spero oppure isolerò

Hi Excalibur,can you tell me how long it takes with your turk burner to reach a temp 330-350*c.I also seem to have a period in my system when the temps stabilize{128*c} and even drop down10-15*c before increasing again.Does anybody else have this problem.Also this last run of yours was it all done around 350*C.
DEREK.

tra pochi giorni l' accensione

da quello che ho visto in foto dedooo utilizza come isolamento del reattore solo un barile molto sottile e quindi dispersivo.ci credo poco che riesca a portarlo a 400 gradi. dedooo hai usato plastica a pellet oppure di grandi dimensioni?

ecco l' immagine

In a few days the 'ignition. from what I've seen in pictures dedooo used as insulation of the reactor only a very thin barrel and then dispersivo.ci not think she can take it to 400 degrees. dedooo you used plastic pellet or large? here 's picture

Very tidy work piccolo chimico,
Wishing you good luck and am hoping it runs as good as it looks.

Thank Excalibur, and wait for what is new for you

Dedooo, thanks. Yes I've identified a number of things to improve with my system. I'll do the changes within a couple of weeks and retest.

With regard to yours, if any of the things I asked about are lacking, I suggest standing back and having a really good think about your set up. There's much that can go wrong for the unwary.

Please tell us what the insulation is around your reactor? It looks really interesting.

Please help me, today filled reactor Plastic entirely, because the pieces were not small, and I have added one liter of engine oil waste, and set on fire slowly, after two hours out liters of oil, then start the diesel out a little bit and all of a sudden, came the plastic melted quickly in a scene scary and intense , where a bug, please help me thank you for all

Dedoo. I'm struggling to understand, sorry.

I'm wondering if you have over-filled the reactor? Have you experienced boil-over? Are you trying to crack plastic without a thermocouple? Do you have a reflux chamber fitted above the reactor?

The pipe on your reactor top flange looks too small?? If that plugs with plastic, you have potential bomb!

Maximum 3/4 full for the reactor for safety with plastic feedstock.

I just completed a 13.5 hour run making 262 liters of diesel and 3 liters of gasoline. The diesel has a specific gravity of .848
Feedstock was waste mineral oils. First drips were after 1.5 hours. The burner heat was from diesel about half the time or alternatively off-gases the remainder.
The gasjars' water level over flowed a number of times. There was at least 3 boil-over events. The oil feed strainer plugged once. A retort feedstock level device did not work quite as expected giving confusing results. (Details on blog, retort page). Reflux temperatures was up to 370°C. A high powered 12v fan recycled from a car radiator was put to good use as ventilation for the retort area.
So I have to be happy with a record amount made!
There is still much to do to improve though. What is apparent is the feedstock being pumped into the retort quenches the temperature too much so there's a lot of downtime waiting for it to recover. Trying to match feed flow to any kind of constant rate was frustrating. There also appears to be a sweet spot for retort level. When it gets low the drip rate flow reduces while too high invites boil-over. If only we could see inside the retort....!
Blog gets an update by the weekend.

Dedooo, it sounds like you need to work on your reflux.

Dedooo, looks like your reactor waste is not fully cracked. When a run is totally completed the residue is like dry carbon char, something like biscuit in texture. I suggest to do multiple runs before clearing out the reactor, but on the last run be sure and bake well so the contents is absolutely dry.

In theory, as fuel is extracted the remaining liquid hydrocarbon will become heavier and heavier. Therefore the boiling point will trend slightly higher and higher.

I've only cleared my Orion reactor just once and I struggled because it is 1.5m deep. All the carbon was on the reactor floor. So the next time I do this task, my plan is to pound the carbon biscuit char to dust and suck it out with a vacuum cleaner.

Hope this helps.
