How to turn plastic waste into diesel fuel cheaply

[wheels]

What is the ideal temp range for retort and reflux to produce liquids when using hdpe and ldpe research give a bunch of different ranges. Still i would like mostly diesel range. Pe plastic seems to have a temper mental thing about it. One day fantastic the other not so fantastic at same temp range. Will water in retort affect results so dramatically. i am using clay pots that are made in areas of bauxite mining. Is there any other catalyst that can be added i cant get zeolite ill have to ship that in.

We have discussed the temperatures many times in past posts and some of those discussion were not so long ago. You need to do some reading, of which we encourage because of the dangers with what this process can come with.
Zeolite is basically Bauxite. Although there are many mixtures depending on the areas the Zeolites are mined. So some can have other Chemicals like Magnesium etc. in the make up. Unless you are heating the catalyst, it is probably not doing anything. Try doing a run with and without and see if there are any variations in the final product.
Yes water can have a huge impact. You can not raise the temperature of water above boiling till it has turned to steam. Once it is steam, the temperature can then rise. Steam can also affect cracking. In fact, the Oil refining industry uses steam in a process called Hydro cracking. It is high temperature and high pressure, so having steam at low pressure and temperature in the retort could possibly cause a negative result rather than positive.
However, the main issue with water is that you will get a flow of gasses come through early in the process and you are falsely lead to think things are working well. Then it all goes dead for awhile and has you scratching your head as to what has happened. After some time, the gas starts to flow again and you are into the actual Hydrocarbon gasses coming through.

What is the procedure if you have diesel with a lower flashpoint?This will not effect run ability of product but may effect volatility whilst handling? Any way to increase this value?

The way I see it is this. Hold the diesel at a temperature that allows the lighter fractions to evaporate off. More or less, the lightest fraction will come off first, followed by the next lightest, etc.
60°C is what I use but higher or lower would work depending on the desired target flashpoint and the timeframe to achieve it.
So, in effect the more light fractions you can extract, the higher the flashpoint figure will be. I suggest to save energy, do it "on the fly" as you are making the diesel. Also it would be worthwhile to re-condense those extracted light fractions for other uses. An ice quench condenser could maximize the fractions condensed, else any non-condensables could be flared off or used as heat.

Excess Gas

Hello.

Is there any way to completely scrub the excess gases and turn them into water or non - flammable state as the BLEST machine claims to do? I currently just burn the excess gases but would like to just get rid of them completely. Any ideas?

flashpoint?

Yes, perfectly OK to blend heavy fractions with lighter fractions like gasoline to make diesel at a usable viscosity. I normally limit the gasoline to 20% max. Gasoline with an ethanol content is more of a problem because the injector pump seals compatibility. In your case I expect you are meaning gasoline and naphtha that you make from plastic. When I'm cracking diesel, I don't separate the gasoline's, naphtha's etc and I do it by only maintaining the diesel reservoir at about 60°C. In this way only the most volatile fractions LPG, benzenes, etc are removed. My condensers are of course in series.

On the subject of waxing, this has been talked about over and over. There are numerous posts detailing the causes and fixes. In short, reducing the reflux temperature has cured the problem. Also taming down the heat force applied to the retort so the contents does not superheat. Careful monitoring the temperatures in the retort, reflux and actual applied-heat temperatures are recommended.

The quality of fuel is more flexible with boilers i don't try to mess with piston engines just as long as long as i distil the naphtha gasoline and keep the diesel fractions i measure viscosity just by comparing times to pump diesel at room temp over a meter long 2mm rod longer it is more accurate for me i would like to know if blending my wmo diesel with the naphtha gasoline from plastic is feasible say between 85%-90% wmo diesel plastic naphtha gas 15%-10% to adjust viscosity along with sta bil fuel stabilizer diesel 100liter to 0.3 stabilizer also i find it hard to mess up pp plastic hdpe ldpe may give waxing question how would prevent waxing from pe as i do not want to make candles factors temp catalyst ect. There maybe something I'm overlooking at times any good experienced advise would be nice

Hello, I've been reading this forum for over a year I've been slowing increasing the size of my setup im now building a 500 gallon reactor will be done next week, i am pursuing this as a business. I live in Jamaica and per liter of diesel costs 1.17 USD yes not gallon liter and that's not ulsd i have been supplying boiler companies as i am up for a grant so i can afford the proper equipment i operate out of the dump at a scrap metal yard wmo= free pp/pe plastic = 1 cent per pound USD so at least living in 3rd world countries has its advantages anyway thanks to the people on this site i am able to do this so much easier to read and learn from other peoples experiences and results will post pics when finished the 500 gallon.

Well done and I wish you an exciting future. You will have some challenges ahead and the first one will be trying to ensure you have a pure plastic type of the PE/PP type, without other types slipping through.
The other challenge will be the Fuel produced, as in, creating a product of quality that can be sold. Producing Fuel of quality is really the most complex and challenging issue. The Pyrolyzing of plastics becomes the easy part.

How to make base oil and gasoline from natural gas?

It's via a very complex and difficult process and in a basic reply, if you don't know, you won't be able to do it and if you do know, then you wouldn't be asking
To expand on that, what I mean is that you would need a really major solid knowledge of Hydrocarbon Chemistry. It requires a specialized process and specialized catalyst. Basically you are taking short Methane and Hydrogen and firstly making Syn Gas. Then you take the Syn Gas chains and join them to make long Hydrocarbon chains. Once that has been done, the long chains then go back through a Fractionating process to be made into the specific hydrocarbons wanted. This process originally took about 40yrs to crack and there are 3500 individual patents covering each step of the entire process. So that tells you how complicated the process is. Yet even though it is complex, it is still done because very pure Hydrocarbon chains are created and they use these a a Base stock for making Synthetic Oils. Hence why good synthetic Oil is expensive.

hello to everyone
How is the base oil and natural gas? Does anyone know?

From Plastic??
The Gas is mainly Hydrogen and a little Methane.
The oil or Hydrocarbon liquids will vary depending on what plastic type you are pyrolyzing and are many different types and the exact make up will vary for everyone, depending on how their Plant cracks the Chains. However, PE and PP both create two basic ranges of Hydrocarbons. Which one are you melting? or is it a mixture of both?
