Very exciting....have you tried broken flower pots as the catalyst? Terra Cotta.
A cracking plant will derive its heat from burning off the carbon from the zeolites. So instead of using kerosene to heat the retort...look at the water gas process, specifically how the "benches" were fired alternately and Siemens Regenerators where used to save the heat. It could be possible to have two alternating catalytic chambers to provide the activation heat for this process.
Another thought is that glycerine can be used as the heat carrier to melt the plastic, as anyone who runs a recovery still, finds out, when they pour the dry glycerine into the cubies after a run.....
"I don't work with collectives. I don't consult, I don't co-operate, I don't collaborate."
Every type of clay has some catalytic properties. ZSM-5 synthetic zeolite would be classed as high catalytic action, unbaked clay would be medium and kiln baked clay would be low. But low does not mean bad, in fact a medium or low catalytic action can prevent overcracking which is a common problem in backyard cracking projects.
I only use 250 gms of catalyst per batch so there would not be enough to provide a significant amount of energy although I know from reading about commercial cracking plants where hundreds of tons of catalyst are used they do recover heat from the regeneration process.
In a way I do recover the energy in the catalyst. I use the wax byproduct mixed with waste sawdust and the spent catalyst to produce fire logs. I burn them in my woodstove and they burn hot and clean.
I did tests without the use of catalysts. successful. 1000 kg for plastic, how many kg of catalyst should I use? What happens if we put into the retort catalyst? I used plastic granules. pp Although who was not vapor. What could be the reason?, I recently'm thinking of doing a system 2000 kg. with electric heating. I put into the retort resistance, although contact with plastics is that okay?
Plastics can be cracked without a catalyst, but more energy is required and it is more difficult to produce a specific fuel. My catalyst comes in contact with the vapours as they leave the retort and I use 1kg of catalyst per 100kg of plastic. You can put a catalyst into the retort with the plastic but you will need more catalyst per kg of plastic.
Using electric heaters within the retort should work ok providing no air can enter the retort at any stage. It may make cleaning and maintenance more difficult.
Thank you for interesting imakebiodiesel.
I've used PP granules. The first batch was very nice. 3 and 4 batch has melted, but did not steam. Why can it?
When cracking plastics, very accurate temperature control is important. You must monitor and control temperature in the retort and at the head of the reflux column to within a couple of degrees C. What temperatures did you use in the batches you have done so far?
Thanks for all the usefull info on your website & videos. I have learned a lot about biodiesel
& kerosene production.I am a handyman myself & started to build a CP Waste Plastic to Kerosene
Processor as per the sketch on one of the posts.If I use a 2" pipe for the catalyst column, what
length should this column be. To produce kerosene, I need clay pot fragments . Must this be coarse
or small pieces. Hope to hear from you soon.
IMB posted on here recently that he will not be checking in here very often anymore due to other priority's.
I would suggest you send him an email or contact him through his website as there is a good chance he will not see your question here...

Thanks for your effort, I do appreciate your time
