How to turn plastic waste into diesel fuel cheaply

[kaguar]

islander,
that`s why refineries have huge cyclones - to remove carbon particles from the stream. My reflux gets always nearly blocked at the end of the process, which is absolutely normal. I`ve got just a simple swirl tube in it which removes just a portion of particles from the stream. Small amount gets deposited in the condenser and the rest flows with the condensed fuel. I`ve noticed that for every 25l of fuel I regularly get about 1l of junk strait from the condenser. Luckily it is heavier than fuel and sits on the bottom of canister. So, that junk is black soot which can`t be mixed with the fuel and that`s why I get clear output.
Regarding your injectors - I don`t know why I`m not surprised and why it sounds so familiar
Centrifuge is a mast in this business, but it is not enough. You have to pass the fuel through 1micron filter as well. I`ve tried centrifuge alone and filter alone. You get good results only if you combine the two.
For your injectors - feel free to use double dosage of Valvoline or WURTH injector cleaner (or if there is anything better). A bit of paint thinner in the fuel will be very helpful as well but it depends on your car`s fuel lines as the thinner will corrode rubber and some sorts of plastic. Good luck

How do you keep it @ 270c ? by air cooling ?

[islander]

Thanks Kaguar ! So I Will invest myself into cyclones soon !
Injectors : mine are the old fashionned bosh, I really don't understand the problem with them. Last Time, they were working well on the test pump but badly smoky on the road with hure loss of power. Never see that before. Maybe the carbon deposit grind them inside ??

islander,
the reflux is air cooled and designed with respect to the operating conditions in the reactor so that it can stay approximately on that temperature.
Injectors - if the injector cleaner doesn`t help you need to take them out and clean in ultrasound bath with a good carb/chocke cleaner.

kerosene condensor

I thought of using iron turnings and the bottom of the refluktor and then a mesh containing the catalyst on top of that.h
All the gasoline will evaporate and diesel should remain. At least I hope so

Hello Jetijs ;
I feel happy everyone is adding the reflux condensor on top of there reactor as I mentioned in my 100-G baby .
The Lid arrangement on top of the reflux condensor is a nice addition for catalyst trials .
How about filling it with iron shavings of lathe machines & Nickel powder used in margarine manufacturing ???

2) You are missing the kerosene condensor .
When I separated the kero range upto-215celsius OUT from the diesel range, the white smoke coming out of my diesel car exhaust almost vanished & the Gravity of the diesel also increased .


I hope U won't mind your students, sending suggestions to U .

Ca(OH)2 works .

To stablize fuel formation H could be added. This might be released by Ca(OH)2 reacting with H2S; I just wasn't focusing on this.

Hello CRMoore ;
1) Pics of your BABY ???
First of all we are still awaiting for you to post the pics of your baby/reactor on this forum . Some of the members have seen them Iam guessing how ?

I don't know why most of the community fellows are shy to send there babes pics , iam quite sure its not PORNO stuff ???

2) Ca(OH)2 works well ; .
With 4% Ca(OH)2 the gasoline range was not performing well the diesel performed well .


I tried again Ca(OH)2 powder again with dosage of 2.50% with the feedstock of (PP/WMO = 85/25) .
All the recovered fuels Gasoline,kero & diesel performance is good .

Bad Smell of the fuel decreased .
Color of the fuels are better but not as good as the 4% one .

So Ca(OH)2 can be added upto 2.50% for sulfur removal I hope this may stabilize the fuel also ???

Any comment would be welcome .

[CRMoore]

Alas no baby

[1) Pics of your BABY ???
First of all we are still awaiting for you to post the pics of your baby/reactor on this forum .

Alas I don't have a reactor (I came to this site looking for one) thus far just the dream/theory.

Catalyst note: Yes straight metal catalyst(Ni, Pd, Rh(for the v. rich)) absorb added H (usually as H2) whereas acidic Zeolites come in with H attached.

Hi
Thank you for the tips. I am learning from you guys as well and every suggestion is apreciated First of all I will try all kinds of different catalysts, including various metals. This setup is perfect for the task.
On the kerosine, as far as I know it is advantageous to have some percentage of kerosine in the diesel as pure diesel is supposed to be very dry without a good lubrication, but kerosine is excelent for this. I am not sure about that. Also, my friend palked to a guy who made his own biodiesel for a while and he also tried Ca(OH)2 in powder form. He also had a centrifuge filter, but he reports that after several thousants kilometers his fuel pump failed due to the high content of calcium hydroxide in the fuel. I have no more info about this, but could it be that Ca(OH)2 somehow dissolves in the fuel or is suspended there in tiny particle form and this can cause fuel pump failures?
Thank you!

Using produced gases

Hi developers, I wanted to point out something that may be of use to you.

At higher pyrolytic temperatures, more gas is produced.

In fact, much gas may be your only desired product, depending on what your needs may be.

There is a thing called a pyro core, which is a tube entering into a porous ceramic cylinder.

Gas is burned on the outer surface of the ceramic cylinder, producing heat.

Here is some connecting information:

http://repository.tamu.edu/bitstream...pdf?sequence=1


and also, Google search engine on "AMERICAN THERMOCATALYTIC CORP. MINEOLA, N.Y. MAKES PYROCORE"

produces these two Google books results:

Popular Science - Google Books

and

Popular Science - Google Books

While these are very old PopSci magazine page reproductions, these are good info.

Also, US Patent Office patent number search on these:

Thermocatalytic Reactors

4416619

3275497

3191659

3179156

and are also good, connecting information, for methods of substantial heating, using produced gases.

To jetijs

I beleive kerosene is dryer than diesel, and it is lighter.

I already distill (not crack) an amount of diesel, and I first got a fraction of white clean kerosene easily.

Then, I had to hear much more to start getting something frol the left diesel, but then it was cracking business clearly.

I can also mention : after a few weeks, I got a black deposit at my distilled kerosene, and it beleive it becames yellowish itself.

For your friend : could it be possible the produced fuel became too high PH, then attack the aluminium areas of the pump ?

I beleive biofuel producers have always the need to check acidic balance of the produced fuel

Kerosene

Using vegetable oil, I was formerly using kerosene to dilute it. About 20/100. After a while, I found my diesel starts not functionning well, power loss and heating a lot.

I poured molybdenum sulfide oil additive into the motor lubricating oil and get immediate positive reasults, later on I stopped using kerosene, and instead, I used gasoline at a rate of around 5/100. Gasoline worked well.

I beleive kerosene is not a good thing for a diesel, Maybe it burns too quickly. I read in a book : the fuel in a diesel has to burn at the good speed. If it burns too quickly you got detonation(1), if burn too slowly you'll get unburn or loss of power and lots of smoke.(i beleive blue smoke)

They have a special experimental diesel motor to determind the cetane rating of a fuel. But maybe we can do it with motor's noise at least !


(1) to my point of view, in this case, you also can have smoke.

[kaguar]

Ca(OH)2 is certainly beneficial in the waste feed because it will remove majority of sulfur and chlorine from the fuel. Furthermore, when heated above 600 C it starts releasing H2O thus you get steam reformation of your fuel which is beneficial too.
I always used non distilled fuel in my machinery and never had issue with smoke. (After distilling I found it never containing more than 5% of lower boiling fractions) The fuel gives the same power as normal diesel and the consumption is on the same level - all that up to the point when injectors and fuel filter get so clogged that the pump can`t suck enough fuel nor deliver enough to the cylinders. Thats the point when the engine becomes very `jumpy` due to uneven distribution of fuel.

[imakebiodiesel]

The heavier the specific gravity ( the weight of one litre) of your fuel the better lubricant it is. Kerosene is not as good a lubricant as diesel. Petrol is not as good as kerosene. Low sulphur diesel in europe weighs 840 gms per litre and some engine manufacturers complain that its lubrication qualities are not good enough.
As a general rule If your diesel type fuel weighs less than 840gms you should add a small proportion of new, non synthetic, motor oil to improve its lubrication quality. Kerosene and petrol is only added to diesel to lower the viscosity or improve the cold weather starting but both reduce the overall performance of diesel fuel.
Im puzzled as to why your friend was adding calcium hydroxide to his biodiesel. Veg oil and biodiesel contain no sulphur or clorine so I cant see the reason for it. it would certainly have changed the ph of the fuel and that would quickly cause damage.

to Kaguar

thanks for your tips, I'm learning from your experience !

I already get my filter clogged, only 3 weeks life for a new filter

This time, I will add a larger filter in addition, I learned Caterpillar have very good quality huge filters for cheap, I'll buy a mount base here :

~WVO~SVO~BIO~Remote 4 u Fuel Diesel Filter Mount~Base~ | eBay

at least I will stop filling expensive small filters. It seems to me it can play a role with smoke sometimes, giving low pressure inside the pump as the advance device of the pump may not be actuated.

Unfortunately the filters are not 1µ. but the VW ones should not be too, and they get clogged. still sludge forming ?


I'll also buy an ultrasound cleaner, that's right it's probably the best way to clean deeply the injectors. until now I was using polishing wax (for mirror finish on stainless steel)

sludge is a real hell. It seems to me it's a real need to get good quality stabilizer for produced fuel

it's a major problem. How to get good one ? the problem the chemicals sold locally for fuel gonna not be specifically designed for a cracked local made diesel !!

otherwise it will only be a story of clogged injectors and blocked filters.

I will post pictures of my sludge, it's a hell.

this is what happens when you store high reactive unstabilized produced fuel into plastic jerrycans :



after about 1 month 1/2 : sludge at the bottom of a drum with 15 liter of produced fuel :
