How to turn plastic waste into diesel fuel cheaply

[wheels]

thanks excalibur...yesterday l was thinking about insulation and i become with the idea of using exhaust insulation.. what about this insulation someone test it?

Exhaust insulation is ideal. But you need a lot of it. The thicker the insulation, the more economical the plant becomes. You need to try to obtain a thickness of about 100mm. Any Fiberglass insulation will work and a layer of Shiny Aluminium Foil aids in reflecting Infra Red heat back in towards the Vessel as well as protecting the Fiberglass insulation.

Black, you must be a fast reader. It took me almost two weeks ;-)

Forget the pics about the retort filling I got to your blog.

Thanks

Hi guys it’s been 5-6 days reading but I finally worked through it all and what a lot I learned! There is so much experience and help that I have decided to start a wmo test plant.
Excalibur when you say you tweak your fuel do you use pump diesel or petrol to get the viscosity were you want it or am I misunderstanding?
How long did the 180L run take and have you got pictures of how you keep filling the retort vessel?

Great forum keep it up all!

Amsoil seems to be a very expensive American synthetic motor cycle oil?

They make a range of products and Diesel Fuel stabilizer is one of them. I have no idea if it would be available in your part of the world though. Another name to try is Mooreys Products.

Yesterday I made 180 liters of diesel which measured .855SG .Feedstock was very ugly WMO, probably diesel engine oil.
I had trouble with pumps, filters and new equipment so I had to cut the run short. The new bigger gasjar worked well. The fuel gives me about 3 - 4 weeks supply.

excalibur did u test your diesel in car? and l read that fuel oxidize after days and turn black....does your diesel turn black also? thanks

Yes. It goes very well, at least as good as bought diesel. I tweak the specific gravity to suit the seasons which I believe helps. None of my fuel turns black after sitting even my runs using plastic feedstock haven't. I can only recall reports of plastic causing the symptom and none with WMO.

Hi FOLKS,
How would one measure the detergent/lubrication value of your diesel product.This seems to be a very important necessity in the finished product!
Any bright ideas?

You need to get a full Chemical analysis of the product you have. A Fuels ability to do those things is determined by what fractions of what Hydrocarbons are in the Liquid. It is the heavier fractions, the ones down on the Oil end of the chains that will be lubricants. The lighter fractions up in the Solvent end will thin those heavier fractions down and make them less able to lubricate. So you need to know exactly what of what is in the batch.
This is where "home made" products become an issue, because no one batch is ever going to be the same. We simply will never have the control, equipment and ability to constantly tweak production to ensure correct and stable chemical mix is created each and every time.
So the easiest way to protect your valuable engine is to add an additive that can ensure you have stability, ant-oxidation and lubrication. I highly recommend Amsoil. It's a real deal Fuel stabilizer unlike many additives on the market. I highly recommend it.

thanks everyone....i try pe plastic without catalyst empty reflux...pp plastic and waste oil comes out yellow at reflux tempreture of 220 but when tempreture rise to 310 it comes black but i find the proplem retort was over 400 so maybe boil over...

All Read - Need to resume

Jetijs

@Jetijs Hi from Argentina, I read all the post from the nro 1 to 121. If it's possible for someone to resume the last model that would work. Jetijs thank you for all that work. Now I'm lost. I undertand the reactor, the coolers for both diesel and gasoline but I get lost in how to avoid wax, use of catalyst and how would be the last model of the invention. If someone could send me a photo or drawing and last result. Thank you!!!

sorry coffee can as retort

thanks, are you sure, may be have oxygen inside??
if i put about 10 kg of used coffe express, how fuel can make??

[wheels]

There are several reasons why you can get wax, so no easy answer. e.g.
The type of plastic used as feedstock.
The temperature of Retort.
The temperature of Reflux.
The use of and temperature of catalyst.
The speed that the gasses are flowing through the system, which determine their heating/cooling time and cracking time. Normally, the hotter the Retort and catalyst, the more cracking and the lighter the Hydrocarbon chains. So you may have your system operating too cold.
This is where you need to play on a small scale and learn all the tricks to best suit your application, before spending money on building continuous feed systems etc, because each change to a design will bring a new set of problems.

hi

can us for feedstock, used coffe express ? like biomasse
