How to turn plastic waste into diesel fuel cheaply

[Beyond Biodiesel]

thanks my friend when l finished my bubbler l try what you say thanks alot

Keep us posted on your results, because every report here helps us all learn.

Find it difficult to believe normal ash would work,as ash is inert,cannot add any catalyst properties.

Almost any porous material will work as a surface catalyst. And, if you watch more carefully a recently posted link to a video of a university in England doing exactly what we are doing the narrator said that they found better results by recycling the ash from their process as catalyst.

It will be in one of these three links:

If you mean PVC, then no. Same with ABS. They are halogenated hydrocarbons, so if you pyrolyze them, then you are likely to kill yourself and anyone withing 50 feet of your pyrolysis unit, unless you go to great lengths to capture, contain and neutralize the HCL and HFL gases that are released. Even if you do, the oils that result from cracking these halogenated hydrocarbons is only going to cause seal damage in most diesel engine IPs. So, stay away from any halogenated hydrocarbons such as: PVC. ABS and PTFE

Hi Thank you for this info. As far as I know numbers 2, 4 and 5 work just fine, number 6 should also work fine.




I don't know about that, it needs to be tested.



Hi, we usually pour off the fuel as the reactor is running, the fuel is hot at this time and if there is wax in it, it is dissolved. But as soon as the poured off liquid fuel cools down, you can see some wax forming. The wax can then be easily separated from the fuel using a coarse filter. There are methods on how to elliminate the wax from forming, but I don't know anything more about that.

I am still developing my WMO distillation apparatus, so I am not at all interested at this time in cat cracking. Although I know that just taking any hydrocarbon up to 800F (425c) will crack a significant amount of it.

I also have read that crushed terracota will work as a catalyst, as well as various volcanic ashes, diatomaceous earth, and even plane old ash from the fire place, or you can burn your coke that you remove from your pyrolysis unit, then use that ash as catalyst.

The take home message is, most of us are backyard enthusiasts, so we do not have to obsess over catalysts. There are a wide range of materials that can be used to crack our plastics back into fuel, so use what you have available to you.

catalyst

thanks so much beyond biodiesel so did you try put clay pots in reflux and retort whats the different? did you make experiment ?

[Beyond Biodiesel]

thanks my friend l weld them. l will try the system if its work l will modify them later l hope it work l will try clay pots

Crushed clay pots will work as catalyst. Ash will work also as catalyst. Volcanic ash, tuffa, perlite, pumice, etc. will also work as catalyst.

condensors

thanks my friend l weld them. l will try the system if its work l will modify them later l hope it work l will try clay pots

[Beyond Biodiesel]

The catalyst goes in either the retort (boiler) or the refluxing column before the first condenser, or both. You are not going to want to weld your condensers shut, because you are going to find you need to take everything apart to service it, or modify it from time to time. This is why tapered thread, or compression fittings are more common and useful in pyrolysis units.

condensor question

l build the retort reflux column and condensors when l have time lmake the bubbler and safty valve my question is this? l don't put any catalyst in condensors l meant they are closed with welding now. so can l test my system? or it doesn't work without catalyst in condenser? thanks

ladanivaca, you might find that gasoline blending works better than diesel fuel blending. You will use less gasoline than diesel fuel to thin out your waste oils.

Post your photos of your plastic pyrolysis system here, because I am sure we all would like to see your system.

Welcome, ladanivaca, my Spanish is not great, and maybe others here are not so good with it, so I translated it for you with the Google translator. Good luck with your process, and do share with us your results.

Since you started out as a blender, I too am a blender, but I found blending gasoline at 20% with WVO at 80% worked best on my engine, and is cheaper than 50% diesel blends.

Those who make their fuel through pyrolysis essentially will be blending their fractions to make fuel, much as we blenders do.

Yes. I already started collecting the informative posts from the most experienced folks. I started with imbd's posts and I will scan through yours too if you don't mind use them.

Whatever I have posted here is public domain, so feel free to use it.

I like your chapter headings. Go for it.
