Abstract
A process for treating waste comprising Mixed Plastic Waste is disclosed. The process includes feeding the waste to a pyrolysis reactor, pyrolysing the waste in the pyrolysis reactor to produce a fuel and using the fuel to run a generator to produce electricity.
Claims17
A process for treating waste comprising mixed plastic waste, the process comprising:
- a. feeding the waste to a pyrolysis reactor, wherein the pyrolysis reactor is a fluidised bed reactor;
- b. pyrolysing the waste in the pyrolysis reactor to produce a pyrolysis product;
- c. passing the pyrolysis product through a condenser to form a liquid fraction and a gas fraction;
- d. measuring an attribute of the liquid fraction, wherein the measured attribute of the liquid fraction is hydrocarbon chain length;
- e. adjusting the temperature and/or residence time of the pyrolysis reactor in response to the measured attribute of the liquid fraction to maintain the attribute of the liquid fraction within a desired range;
- and
- f. storing the liquid fraction as a liquid, a solid, or a mixture of a liquid and a solid in a tank.
