The issue of thermal pyrolysis of waste plastics
Thread Content
What are the process parameters for producing products such as diesel and gasoline from waste plastics? What are the specific values? In my opinion, the key factors are the residence time and temperature in the extruder; a longer residence time leads to more severe cracking, resulting in a higher proportion of gaseous components； The same is true for high temperatures; the temperature of PE plastics is generally above 360 degrees. Another is the catalyst, which can increase oil and gas production rates. Please give better suggestions!
The newly introduced standards state that waste materials should not be used for oil refining; it is likely that various plastic additives, along with the inherent properties of the plastic itself, result in oil products of poor quality, and the production process also generates significant pollution
Many types of waste plastic cannot be reused for granulation, and since they are mixtures, sorting is also of little use. Such plastics only have some value through pyrolysis. Pollution can be reduced by improving process control measures, but if left unaddressed, it causes greater environmental damage.
I would like to have a thorough discussion with you regarding the pyrolysis of waste plastics
I am quite interested in thermal pyrolysis; I have been working on this for two years now. The environmental issues related to this process have been resolved, and oil with a specific gravity between 0.78 and 0.8 is produced
