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.
Claims18
A method of processing pyrolysis oil, the method comprising mixing the pyrolysis oil with at least a portion of char derived from pyrolysis of plastic, wherein the mixing causes the char to adsorb at least some chlorides from the pyrolysis oil to form a purified pyrolysis oil and used char.
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 at least a portion of char formed from the pyrolyzing of the plastic to remove at least some chlorides from the pyrolysis oil by adsorption of the chlorides onto the char 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.
