How to turn plastic waste into diesel fuel cheaply

[Babataku]

Hi All,

Need some help:

1.I have found some BHT Food grade available, has anyone tried this or i need to use some other BHT for Industrial or specifically for petroleum industry?

2. In what proportion should i add the BHT to the produced fuel? 1Kg to how many liters,etc?

Please help, i need to deal with stability of produced fuel.

Hi Jetijs, I'm in the process of buying the parts to create this fantastic plastic/diesel converter. Just a question about the aluminium oxide bricks - can they be simply firebricks cut into the correct shape ?

Yes,

What are the dimensions (how thick is necessary)?

I found 4" thick insulation is necessary for efficiency; however, only the first inch (2.5cm) needs to be high temperature, the rest does not need to be fire brick, it could be cardboard that is coated with a thin layer of steel or aluminum sheet metal.

Also where did you buy your metal cage from ?

I believe a friend welded it for him.

What type of metal is it made out of ?

The cage is steel.

And lastly, the heating coils - what voltage are they supposed to be,

220 V is common.

is the type of metal important,

Yes, nichrome wire.

and what lengths are we talking ?

Length is relative to how much resistence you want in the wire, which is related to how many watts you want to dump into your retort, which is related to watt density, which you will have to figure out on your own, but I covered my retort with nichrome wire.

I'm buying a 200 L steel drum. Thanks in advance,
Georgia

A steel drum, or barrel is insufficient gauge for a retort. You will want something more substantial, like 1/16" (1.5mm) (14 AWG) steel, preferably stainless steel.

BHT Butylated hydroxytoluene

Butylated hydroxytoluene, also known as butylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties.

Thanks, AAS, that is really useful information for people who are cracking plastics into diesel fuel.

Thanks AAS,

Where are you buying from in South Africa? which company and do they accept purchases in small qty?

regards

Sigma Aldrich should provide lab quantity, expensive though. LArge quantities needs to be imported via Sasol(Merisol) from America.

Literature confirms BHT as the bench mark for stabilization, however not there yet, still sorting out my quality of my fuel product.

AAS,

Many Thanks. also got a quote from a company called CJP Chemicals in Joburg, they sell 25Kg packs.

Is Food Grade OK for our intended use?

AN educated guess would be definitely, we are looking at say 50 parts per million for a start, with that amount of dilution, I really don't care if it's 90% or 95% instead of closer to 100%.

Please let me know what your results are. Degradation in these tipes of fuels is higher that conventional fuels due to excess free radicals. Perhaps you should try to go up to 250 or even 500 ppm.

Do you have a lab in mind to do your degradation studies?
Probably a 3 month accelerated aging would be appropriate.
Remember your two control samples using normal diesel and one of your fuel fractions without stabilization.
Sediment or gum formation should be clearly visible.

PErhaps as a start just put samples in an over at say 50 degrees and possibly a UV light if you have or just leave in sun light for a month and let me know the results.

Visual result should be enough to get a feeling of what percentage you need before expensive lab testing is needed and then you can possibly only send one sample for testing.

I will let you know in a week or so, i have to place an order and then do the experiments

Welcome

Is the plant to be electrically heated? Else is it to be fired with LPG, retort gases, diesel, kerosene, etc.?

Agreed. 20liter retort is small for commercial purpose. What size were you considering?

Hello all I have now finished reading the 107 page 'I would like to thank all who contributed to the publication of his ideas on the subject' do not blame Jetijs and imb have returned to what they're writing 'but I would encourage
Excalibur and Beyond Biodiesel to provide support to all and thank you

[Chris@NL]

First i thought iT would be a good idea to use the fuel and gas for heating the device. But after some Reading electric heating looks better.
Its not so expensive as i thought it would be.
Also it works cleaner i guess.

I have a very big power supply, so that won't be an issue.

[Chris@NL]

To answer your last question. I would go for a device for about 500 kg.

And i would like to have an automatic feed for plastic and maybe also automatic char removal. (Sorry for my bad english)

I was thinking to use an old extruder from an injection moulding machine to preheat the plastic and to inject it into the reactor.

Can someone explain the different types of metal because in Holland i think they use other names for this?

What you have thought about pre heating in extruder is very correct idea . You are on right track .

Welcome Chris, building a pilot plant is a necessary developmental process for each and everyone who wishes to design and build a pyrolysis unit, because in a pilot plant you can make lots of mistakes without killing a lot of people.

Using an old extruder from an injection molding machine to preheat the plastic and to inject it into the reactor sounds like an excellent idea. We should all go looking for such a device.
