Abstract
Disclosed is a process for the alteration of the ratio of the specific gravities of the oil and water phases resulting from the conversion of biomass to liquid products, the reduction of the conductivity and of metals of the product mixture, which each can aid in the removal of solids contained in the oil phase.
Claims91
A method comprising:
- a) providing a first mixture comprising reaction products produced from catalytic conversion of biomass at temperatures ranging from 300° C. to 1000° C., wherein the reaction products include a first oil phase comprising biomass-derived, carbon-containing compounds and a first aqueous phase comprising water, wherein the ratio of the specific gravities of the first oil phase to the first aqueous phase (SGR1) is greater than 1.0;
- b) modifying the specific gravity of at least one of said first oil phase and said first aqueous phase, thereby resulting in a second mixture having a second oil phase and a second aqueous phase, wherein the ratio of the specific gravities of said second oil phase to said second aqueous phase (SGR2) is less than 1.0;
- and
- c) separating at least a portion of said second oil phase from said second mixture.

- wherein a specific gravity modifier comprising light cycle oil is combined with said first oil phase of said first mixture, thereby forming said second mixture, wherein the ratio by volume of said light cycle oil to said first oil phase is in the range of from about 0.05:1 to about 1:1;
- and wherein the specific gravity of said second oil phase is lower than the specific gravity of said first oil phase;
- and
- c) separating at least a portion of said second oil phase from said second mixture.
