Abstract

The present disclosure relates to a liquid composition that includes an alkane concentration between 40 wt % and 55 wt %, and an alkene concentration between greater than 0 wt % and 20 wt %, where cyclopentenone accounts for greater than 65 wt % of the alkane concentration. In some embodiments of the present disclosure, the liquid composition may further include phenol. In some embodiments of the present disclosure, at least a portion of the liquid composition may be bioderived.

         2 . The liquid composition of  claim 1 , further comprising phenol. 
     
     
         3 . The liquid composition of  claim 1 , wherein at least a portion of the liquid composition is bioderived. 
     
     
         4 . A liquid composition comprising:
 a concentration of single ring aromatics of less than 40 wt %;   a concentration of two ring aromatics of less than 60 wt %; and   a concentration of oxygenates of less than 20 wt %.   
     
     
         5 . The liquid composition of  claim 4 , wherein greater than 70 wt % of the oxygenates comprises at least one of butanone or butenone. 
     
     
         6 . The liquid composition of  claim 4 , wherein greater than 25 wt % of the oxygenates comprises pentenone. 
     
     
         7 . The liquid composition of  claim 4 , wherein:
 about 20 wt % of the oxygenates comprise a methyl phenol; and   about 20 wt % of the oxygenates comprise an alkyl phenol.   
     
     
         8 . The liquid composition of  claim 4 , wherein about 55 wt % of the oxygenates comprise benzene diol. 
     
     
         9 . The liquid composition of  claim 4 , wherein at least a portion of the liquid composition is bioderived. 
     
     
         10 . A method comprising:
 thermally reacting a biomass to produce a bio-oil; and   upgrading the bio-oil to produce a liquid product, wherein:   the thermally reacting is performed in a pyrolysis reactor, and   the upgrading is performed an upgrading reactor.   
     
     
         11 . The method of  claim 10 , wherein:
 the liquid product comprises:   a concentration of single ring aromatics of less than 40 wt %;   a concentration of two ring aromatics of less than 60 wt %; and   a concentration of oxygenates of less than 20 wt %.   
     
     
         12 . The method of  claim 10 , wherein the upgrading reactor is a fluidized bed reactor. 
     
     
         13 . The method of  claim 10 , wherein the pyrolysis reactor is a catalytic fast pyrolysis reactor. 
     
     
         14 . The method of  claim 10 , wherein the biomass comprises at least one of a wood or a grass. 
     
     
         15 . The method of  claim 10 , further comprising:
 prior to the upgrading, combining the bio-oil with a second oil, wherein:   the upgrading further comprises the second oil.   
     
     
         16 . The method of  claim 15 , wherein the second oil comprises at least one of a vacuum gas oil, a light cycle oil, or a naphthenic. 
     
     
         17 . The method of  claim 15 , wherein the combining comprises mechanically mixing the bio-oil and the second oil to form a suspension. 
     
     
         18 . The method of  claim 17 , further comprising:
 before the upgrading, phase separating the suspension to form a light phase oil and a heavy phase oil.   
     
     
         19 . The method of  claim 18 , wherein the upgrading is performed on the heavy phase oil. 
     
     
         20 . A method comprising:
 thermally reacting a biomass to produce a bio-oil;   mixing the bio-oil with a second oil comprising at least one of a vacuum gas oil, a light cycle oil, or a naphthenic to form a suspension;   phase separating the suspension to form a light phase oil and a heavy phase oil; and   upgrading the heavy phase oil to produce a liquid product, wherein:   the thermally reacting is performed in a pyrolysis reactor, and   the upgrading is performed an upgrading reactor.
