Abstract
Systems and methods for removing contaminants from pyrolysis oil are disclosed. The removal of the contaminants, such as chlorides, involves mixing the pyrolysis oil with char, in a mixing unit, wherein the char was formed as a by-product of the pyrolysis of plastic to produce pyoil.
Claims20
A method of processing pyrolysis oil, the method comprising mixing the pyrolysis oil with char derived from pyrolysis of plastic and thereby remove at least some material from the pyrolysis oil.
A method of processing pyrolysis oil, the method comprising:
- pyrolyzing plastic, in a pyrolysis reactor, to form pyrolysis oil and char;
- mixing the pyrolysis oil with char formed from the pyrolyzing of the plastic or from pyrolyzing of other plastic to remove at least some chloride compounds from the pyrolysis oil and thereby form a purified pyrolysis oil and used char;
- separating the used char from the purified pyrolysis oil;
- and
- cracking the purified pyrolysis oil to produce one or more olefins.
