Abstract
Systems and methods of processing pyoil are disclosed. A pyoil is treated by an adsorbent to trap, and/or adsorb gum and/or gum precursors and other heteroatom containing components, thereby removing the gum and/or gum precursors from the pyoil and producing a purified pyoil. The purified pyoil can then be cracked to produce chemicals including olefins and aromatics.
Claims19
A method of processing pyrolysis oil (pyoil), the method comprising the following steps:
- treating the pyoil with an adsorbent and thereby removing gum and/or gum precursors from the pyoil to produce a purified pyoil;
- and
- cracking the purified pyoil under reaction conditions sufficient to produce olefins and aromatics,
- wherein the adsorbent comprises:
- an activated charcoal (carbon);
- and
- a molecular sieve comprising K12 [(AlO2)12(SiO2)12]·nH2O, Na12[(AlO2)12(SiO2)12]·nH2O, Ca4.5[(AlO2)12(SiO2)12]·nH2O, Na86[(AlO2)86(SiO2)106]·nH2O, or combinations thereof.

A method of processing pyoil, the method comprising:
- treating the pyoil with one or more non-silica based adsorbents and thereby removing gum and/or gum precursors from the pyoil to produce a purified pyoil;
- and
- utilizing the purified pyoil as a liquid fuel,
- wherein the non-silica based adsorbents comprise:
- an activated charcoal (carbon);
- and
- a molecular sieve comprising K12[(AlO2)12(SiO2)12]·nH2O, Na12[(AlO2)12(SiO2)12]·nH2O, Ca4.5[(AlO2)12(SiO2)12]·nH2O, Na86[(AlO2)86(SiO2)106]·nH2O, or combinations thereof.
