Produce fuel from plastic

License :

Introduction

Plastic pyrolysis is a distillation process that allows plastic waste to be converted into fuel. Plastic waste is heated above 400°C in a first tank into a gas. Depending on condensation (cooling) temperatures, several types of fuel are produced : - between 390 and 170°C, the gas condensates into diesel fuel. - between 210 and 20°C, the gas condensates into gasoline. - below 20°C, there remains non-condensable residual gas that can be burned to provide heat to the process.

In this prototype, we are only using polypropylene (PP) and/or high density polyethylene (HDPE) and low density (LDPE). Please note that using mostly polypropylene will produce more gasoline, while using mostly polyethylene will produce more diesel fuel. It is however possible to mix both.

Materials

  • 1 large stainless steel tank with lid
  • 3 small stainless steel tanks
  • copper pipes (diameter 6mm)
  • 7 copper uniseal joint (for watertightness of joints)
  • O-ring (for watertightness of tanks)
  • Plastic waste PP and/or HDPE/LDPE

Tools

  • Solder
  • A heating system (min. 400°C)
  • butane/propane gas canister (375mL)

Step 1 - Pack the first tank with plastic

For this test, plastic waste is mostly polypropylene.



Step 2 - Preheat the second tank

Preheating is necessary. It allows for the condensation of gases at high temperature before passing through the last two tanks.



Step 3 - Formation of residual gas

Let plastic waste consume itself until non-condensable gas forms. It comes as an addition to the gas initially used. For this test, 125mL of canister gas has been used, to which has been added residual gas.



Step 4 - Retrieval of fuel

Here, the machine was heated during roughly one hour. Switch off the system and let it cool down before opening the tanks. We get around 125mL of fuel in tank n°2 and 30mL of fuel in tank n°3.

  • Result of test to confirm in the lab
