Japanese Scientist Invents Portable Machine That Reconverts Plastics to Oil - August 23, 2010, 12:10 AM

I'm still waiting for my genius moment/idea.


We're getting there ....

We have been doing this with a plasma lance at MIT for like 20 years...

There is a company in Mongomery County Md, I believe out of their recycling facility thats been doing this for years.

Company Recycles Plastic Into Oil

Pilot recycling program turns plastics into oil

Hahahaha...and the one we had makes a plasma torch look like a cigarette lighter...it was like 400kW if I remember correctly, the bus bars were as big as my wrists (2-4000 amps). But whatever you put in the chamber went away, it was designed to reduce trash to it's component elements...all that came out was a molten metal mix, carbon, and a variety of gases

By definition, it would have to be. Bear in mind that "synthetic" lubricating oil is still made from petroleum. Synthetic just means the feedstock materials are altered chemically. Non-synthetic lubricating oil is simply a blend of specific hydrocarbons extracted during the normal refining process. Synthetics take those materials and chemically modify them to enhance specific properties.

Although, since any plastics-to-oil process results in a relatively non-specific hydrocarbon blend (depending on the process) without tailored properties, the oil created would be closer to non-synthetic lubricating oil blended with gasoline or diesel (basically, crude oil) than it would be to synthetic oil.

But to your point, there is more than one way to extract oil from petro based products however the amount of energy needed to get gas to ionize up to plasma temperature can be pretty high depending on if you want Hot or Cold plasma.

There is a company that turns all trash into usable oil, not just plastics. it was on the science channel.

You actually aren't ionizing the waste stream into a plasma, in most of these processes, you have a jet of plasma (preferably hydrogen a oxygen yields too much CO2 in the process) that delivers heat and ionized atoms to the waste--it ends up breaking down the chemical bonds in the waste materials more efficiently than heat alone due to the extreme reactivity of the ionized and excited gas atoms impacting it. It's more like a catalyzed reaction, without the catalyst--energy balance depends on the waste material and gas used in the plasma jet. While the efficiency of converting electricity into energy in the jet is very high (70-90%), the energy cannot be easily recovered (it becomes heat), and the process is used as it permits less overall efficiency loss in the overall chemical conversion of the waste. With proper design (using the high temperature exhaust of the conversion to preheat and vaporize the waste stream to allow a good gas-to-plasma interaction), it can be pretty efficient, but at it's root, it's similar to the process of making charcoal or coke--by heating a hydrocarbon (wood, coal, or oil) in an oxygen free environment, the material is reduced, leaving a high carbon solid (charcoal or coke) and a low carbon gas (syngas, coke-gas, etc) that can be burned at high temperature and efficiency. The plasma just permits this to happen more rapidly and at lower bulk reactor temperatures...in effect, it's like coal gassification, but yielding a solid carbon byproduct rather than normal (water-gas shift reaction) co2 gas byproduct (and it's much easier to sequester a solid)

Oil is easy and abundant.

Cheap oil is harder.

In the places I think he'll market this no on has jobs, and there is a lot of trash. Offering a system that would reward trash conversion to profitable by products in third world countries could serve multiple purposes, but specifically waste recycling and profit.


SV650s for SALE!!!

Especially when the government won't let you drill in places where there is oil (shallow east, west, and gulf coast, national petroleum reserve), then claims we are running out of places...
