What is the newest pyrolysis technology?
Newest pyrolysis technology:
Waste plastic usually takes the
pyrolysis technology to do recycling usage.Pyrolysis technology is the industrial process of breaking down large molecules of plastic/tire into smaller molecules of oil,gas and carbon black.The pyrolysis technology of waste plastic not only no pollution to the environment but also recycle the energy effectively.That is to say,pyrolysis technology of plastic is the inverse process of manufacturing plastic products by crude oil materials.Our doing company add different catalyst to the different plastic materials for pyrolysis.Comparing with the domestic pyrolysis technology,we improve the oil yield and quality.
- Because the plastic is made of different raw material, the pyrolysis process is also a little different.PE,PP and PS are decomposed at 300-400 centigrade degrees.But the PVC is decomposed at two stages which are 200-300 and 300-400 centigrade degrees.The PVC may release HCL and hydrocarbon,and then break down step by step.Due to the corrosivity of HCL,and it will effect the pyrolysis catalyst,life span and the oil quality.Then the pyrolysis technology requests that the PVC should be less than 30% of the waste plastic.
- The molecules of different plastic is very different,so the final product and oil yield is different.Generally,there are four kinds of final pyrolysis products: hydrocarbon gas(C1-C5), oil (gasoline is C5-C11,diesel oil is C12-C20,the heavy oil is C20), paraffin and coke.
