How to turn plastic waste into diesel fuel cheaply

[Beyond Biodiesel]

I got a question, is this patent? Or can I use this construction and the idea in my schoolproject?

The pyrolysis process and other methods that we have been discussing are old, have been around since the 19th century, and are common laboratory practices today, so anyone could duplicate our practices and methods without violating a patent.

I have read the initial thread, however i didn't have the time to go through all the replays so my apologies if I ask same question again.

Actually I have 2 simple questions regarding this invention.

1st what is total ROI after subtracting cost of electricity and plastic (which probably will be zero if just get it from the garbage) and also the cost for the refining process of the hard oil into diesel fuel.

And my second question is: can the same method be used to turn plastic into gasoline rather diesel.

I have a scooter that runs on gasoline and I will primarily need it for it.

Thank you.

Your questions are far too broad for a good answer. Only YOU can determine ROI and risk. Each case wil be different, depending on feedstock, and decisions you choose to make regarding capacity, location, safety measures, etc.

The reality is, this is only useful for low tech backyard processing, at high safety risks, no taxes/regulations to deal with, and significant amount of operator labor. If you're wiling to deal with a home project that will keep you busy on a continuous basis, and consider your time, collection cost, aggravation, and labor are free, then your ROI would be very high, compared to those looking to automate the process, increase safety margin, go to low volume commercial scale, and pay regulatory compliance, licensing, monitoring, taxes, etc.

As for the gasoline fraction, you will find plenty of info in this thread regarding the correct condensing temperature window for gasoline, based on your feedstock and possibly catalyst, too.

C to F. The temp of the plastic

What is the temp of the plastic heater while melting the plastic
400 f or C.

thank you for your whole reply. Can you give me a direct link of some threads regarding your last sentence ?

I have read more of the thread and got few insights. However I still have few more questions in mind. Home someone give a quick reply to them.

1. What kind of air-proofed tank is most appropriate for a boiler? (give give some suggestions?

2. What kind of thermometer could be used if I don't heat it via electricity but with propane gas and how could I attach safely it inside the boiler without air to gets in? Like the one on this video.

3. What catalyst is best suited to make gasoline and where exactly I should put it.


Thanks to those who can give detailed answers.

1. What kind of air-proofed tank is most appropriate for a boiler? Old LPG cylinder

2. What kind of thermometer?
Like this .
Put the tiny probe inside a blind steel tube that protrudes into the reactor.

how can we check the properties of fuel obtain from plastic
thanks

Thanks but how do you put the plastic in? Or you need to cut the top and weld it again with a flange ?

Another point that came to my mind is: you will probably agree that is a good idea to have some pressure relief valve. What should be it and where to put it ?

See Jetijs flanges on the first pages, especially here

I have discovered why we have not heard from Jetijs for a while. In fact it is remarkable that he has time to post at all considering that he was pedalling 60,000 km from China to London for the last two years

It more looks like the inside of an old boiler rather used LPG cylinder. But thanks anyway.

By the way do you know what catalyst does he uses and where exactly he puts it - in the reactor or in the condensers and does it matter what catalyst to use for the different types of fuel?

Gasoline (naptha) production from pyrolysis of plastics is about 50%. The Diesel fuel fraction is about 35%.

3. What catalyst is best suited to make gasoline and where exactly I should put it.

As has already been discussed here cat cracking only increases the yield by 10%, while increasing the complexity of the design by 75%. So, the conclusion is cat cracking is strictly for high volume applications.

I haven't read thought the whole thread but thanks for sharing this.

I have one more question regarding the condensers. Is there some filter or cooling substance inside them or are they just empty?

I understand that from the 3 condensers come out 3 different types of fuel depending on the temperature. How do you cool and heat them ?

I talk about those 3 condensers. Also give some tips of what pipes you have used and could be best appropriate for them.
