  • liquid catalyst

    Seems like using zeolite directly in the reactor makes things alot simplier. I just wonder how long you can continue to use it before it needs to be changed. I found this interesting video online. What else can be used directly on the reactor for cracking?

    • My experiments with catalysts in the liquid phase were not successful but that does not mean it cant be done.
      My current method involves adding conditioners to the liquid phase plastic ( lime, wood ash etc) and using a clay based catalyst in the gas phase.
      Zeolites are just highly refined alumina silicates. Nearly all common clays will contain a significant proportion of alumina silicates so can be used instead.
      So far my clay catalysts dont last long, a couple of batches and then they deteriorate. However with common clay, its cheap and plentiful so it does not matter.
      Obviously local clays vary from region to region, so you just have to try it and see.

      • fuel from plastic website

        well its been a while since I have been able to mess with this stuff and my info is old news compared with what you people have done so I opened the website for all to see. Fuel From Plastic

        • Hi Carbogger, It was you who got me started on all this, I subscribed to your site a year or so ago and it was a great help.
          Since then I have built a small reactor and done 23 "burns" testing different mixes of plastic, types of catalyst, additives and temperature ranges. Im now starting on a larger reactor which I hope will be up and running by next year. It will start with about 30-40 kilos in the pot and more can be added as the burn progresses.
          Many thanks for your help.

          • Carbogger,
            This is OUTSTANDING!!! And thank you for sharing!
            How do you plan on implementing the continuous feed through the 3" valve? From an evacuated chamber prior to opening the valve?
            The other question is how do you plan on continuously collecting the leftover carbon and other remains out of the system?
            Good stuff! Keep up the good work!

            • Hi all!

              Does anyone know about sintetic zeolite european (per tonne) price?
              How many batches can you reuse them?
              Some european providers?

              Thanks in advance!

              • What about benzene and others polycyclic aromatics. Aromatics are very cancerogenic.

                • As part of our school science project we had a sample of our fuel analysed by gas chromatography and mass spectrometer. the results were very interesting. The fuel was made up of mostly unsaturated hydrocarbons in the C10 to C18 range peaking at C15.
                  Cyclic hydrocarbons (aromatics) were almost absent,less than 2% which is good news as these are quite toxic.
                  Currently diesel in the US can contain up to 30% aromatics and new legislation is on the way to reduce this to 10% eventually.

                  • Thanks, Imakebiodiesel!
                    Nice job!


                    What was your feedstock?

                    Comment


                    • The sample that was tested was 75% polyethylene and 25% polypropylene. This is typical of my mixes. Some times I will add up to 5 % polystyrene, but no more.

                      • the bubbler system

                        I'm new to this process but I had a man over here telling me about his system and I was curious about it in reference to yours. He uses 2 55 gallon steel drums. He puts the plastic/tires into one. He heats it using wood, then it goes into a copper tube into the other barrel that is half filled with water. From there it is release into a large 300 gallon tank and leftover gases run through a pipe that is run under his first tank to help fuel the process. He filters it twice to get home heating oil and 3/4 times to get gas that he runs his truck with. Is this similar to your system or am I missing something? Could you also tell me if styrafoam is safe to use and what are the best plastics? I read what you said about how the plastics were made but not what kind to use. We have numbers on all our plastics from a 1 to a 9. If you know about that system can you tell me which numbers are the best to use? Thank you so much for the videos and charts.

                          • White spirit from waste plastic

                            [QUOTE=Asad Farooqui [/QUOTE]

                            Hello everbody .
                            NO NEWS is not a good news .

                            There is a complete silence at the forum , its very bad . I would request the community that We should keep it alive .

                            Anyway Nowadays i was experimenting with a different liquid product made from waste Plastic .
                            Following is its detail, In my next message I will explain how I did it .


                            White spirit
                            [CAS 64475-85-0][1][2][3], also known as Mineral spirits. It is a paraffin-derived clear, transparent liquid which is a common organic solvent used in painting and decorating.
                            In 1924, an Atlanta dry cleaner named W. J. Stoddard worked with Lloyd E. Jackson of the Mellon Research Institute to develop specifications for a less volatile dry cleaning solvent as an alternative to more volatile petroleum solvents. Dry cleaners began using it in 1928 and it was the predominant dry cleaning solvent in the United States from the late 1920s until the late 1950s.

                            It is a mixture of aliphatic and alicyclic C7 to C12 hydrocarbons with a maximum content of 25% of C7 to C12 aromatic hydrocarbons.
                            Initial boiling point of 149 F (65 C),
                            Dry point of approximately 156 F (69 C),
                            Specific mass of 0.7 g/cc.


                            White spirit is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products.

                            In western Europe about 60% of the total white spirit consumption is used in paints, lacquers and varnishes. White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after decorating. Its paint thinning properties enable brushes to be cleaned (by preventing the paint from hardening and ruining the bristles), enabling them to be reused.

                            The best thing about White spirit is that there is no restriction of producing it in my country .
                            Hopefully same would be the case in other countries also .


                            Love U all .

                            • Dreaming forward.

                              Have you seen GEK set-ups for home-based gasification? That's analogous to what I'd like to see for plastic-to-oil units as I don't have the skill/tools to build one. There are several levels of gasification kits from plans that start with cutting the sheet metal to those that include part to be welded to the wench ready/assembled type. The GEK staff run demos and an online forum.
