how much tempertur of reactor

plz any member send me anser of my qution tanks

I just happened to be passing by one of the scrap metal dealers today. Sure enough there were some 3-4"pipe flanges I could have had.

Scrap was closed today but I was able to see something what could be modified for burner under the reactor as well as a flange - brake drums from semi or its trailer


Hopefully, I'll be able to go again either tomorrow or Tue.

The key is lack of oxigen inside the pyro chamber, so using SVO may work.
WVO with all those acids inside, i dont like it,but what the hell, ABS gives out an acid acid too

As soon as i have my setup ready i will test some WVO

Oh, cool. Please keep us posted if you get to it before I do.
No doubt that whichever way you go there's issues, things to know and difficulties to overcome. That's where this forum is so great in that it gives us opportunity to help each other.
So, a big thanks to the forum moderators and to those who contribute.

V, that's good lateral thinking. I like the idea. Funnily enough, on Saturday at a scrapyard I was saying that a possibility to make a tank could be to fabricate it from used truck rims. The idea being that the vessel could be made to whatever height by welding together enough rims in a stack. Even at a later stage, the vessel could be lengthened by adding another rim. Your idea of using the flange for the hatch was something that didn't occur to me at the time. Nice one!

Faki, Is this the answer to your question: Reactor vessel between 380-450 ° C.

I have to figure out how to make this unit with available parts which are often laying around. I could get two drums today for free but want to see if I can get two matching. A twin from semi trailer. I have couple projects and I want to get them done this summer, if I can.
There is a guy in mainland AU who makes a stoves from three of them stacked together @ $350 a piece. The walls on these drums are almost 1/2" thick.

Thanks

Nice to see the thread so active. A testament to jetis's genius.

I got 7 replies fro CN. Now, I have to determine which are legitimate and which are fraud attempt . I'm gonna try to negotiate a sample.
It would be nice if this could work since I'll be able to order more and share with those who are into building. I want 12" - 14" set of flanges which would fit any small size (10 - 200L) reactor vessel. Will keep posted.

@Excalibur Nice to see your setup going

I was looking at the Wikipedia article on vegetable oils to try to get an idea of how much potential they actually have in producing hydrocarbons in the right range for our purposes. It looks like they might produce some usable fuel based on the amount of hydrogen and carbon in some of the longer fatty acids, but they also contain a significant amount of oxygen. My guess is that fuels produced from pyrolyzing WVO will probably suffer from a lot of oxidation as a result. :/

One thing I don't recall seeing mentioned at any point in this thread, though, is asphalt shingles. They are about 40% asphalt and 60% aggregate, but they are incredibly dense, easy to chop up, and you can get sometimes get a ton of them for free if you find someone replacing their roof (Like, a literal ton, not a figurative one...).

Asphalt has a very high vaporization temperature, so the reactor would probably have to be incredibly hot to get it to start cracking into the smaller fractions. It would almost certainly require a catalyst to help reduce the energy needs, but several of you guys have already cracked that particular nut with clay.

I don't have a reactor or the ability to build one any time soon, but perhaps someone who has one would like to give shingles a try at some point?

My thermocouple arrived yesterday from HongKong. It took exactly 6 days to land on my doorstep. One of the main reasons I went with this is because the feedback for the seller was so much better than some of the others.

So I got down to business staying with my simplified reactor. I fitted a bigger flue which worked much better.
The thermocouple was inserted in the top of the reactor, into a tube which was brazed to the BSP blanking plug.
I started the fire going and ran it for about 5-6hours. There were a few issues. Some of wood was wet and it rained as well.
At first white lumps were appearing, floating in the water. I soon realized this was wax and not bits of plastic.
So I made some liters of creamy yellow wax.

Ok, so next I need to get my condensers arranged. I picked up some great vessels for this purpose from a scrap metal dealer yesterday.
With regard to piping of reflux condensers, I notice that the "in" and "out" are sometimes in the top and sometimes in the side, near the top. Is there particular advantage to favor either top or side,near top?

Also, I've got various oils I'd like to try, amongst them is about 400L of vegetable oils. Is the theory the same for vege oils in a Pyrolysis reactor? Logically I'd think it is.

I've just started my 3rd sweep of reading all the posts from the start. I hope to be finished by the end of the week. It's amazing how much more the info makes sense each subsequent time it's read. Of course my memory isnt what it used to be either!

In regard to the piping. I would place the reflux (catalyst) right above the main reactor. This way any impurities will fall back into it. As for the condensers, I would have inlets on the side and outlets of vapors from the top.
As far as veggie oils, I would say it is the same process but the temperature may need to be adjusted.

Thanks.
I made the condensers earlier today. They got side ins & outs. I was undecided right up untill I brazed the last of the sockets on. After the first socket went on, I saw that there would be only 4inches gap to a centrally fitted outlet. If I put the outlet at 180degrees, it would be 8inches. I went with 8inches and the 180degree position. Should this work OK, it saves extra plumbing elbows, not to mention the expense of those elbows!

Re: catalyst, I'll have to have a refresher course on that. Agreed as to position... right above reactor looks like a good spot.

Veggie oil. Yes of course... the temperature might very well be something different. I need to be ready to test a variety of temperature range. It will be interesting trying it out. Thanks.

I hope that goes well. I'd not know who to trust. Good luck.

Good day like you would ask if anyone knows how to make a catalyst if a sketch or drawing shall release the board and whether there should be water in the three cylinders diesel, kerosene and gasoline

[aleksandarrado]

Tell me how to make catalysts, whether in bottles to put water
