Abstract
Compositions are provided for hydrocarbon separation applications. In some embodiments, the composition comprises lignin, in particular technical lignin, and at least one strain of bacteria capable of biosurfactant production and/or a biosurfactant produced by at least one such isolated strain of bacteria. Also provided is a method for separating hydrocarbons from a hydrocarbon-containing material.
Claims8
A method for separating hydrocarbons from a hydrocarbon-containing material, the method comprising:
- a) combining the hydrocarbon-containing material, wherein the hydrocarbon-containing material comprises hydrocarbon-containing particulate matter, a hydrocarbon-containing liquid, or a combination thereof, with a composition comprising i) lignin and ii) at least one isolated strain of bacteria capable of producing at least one biosurfactant and/or at least one biosurfactant produced from the at least one isolated strain of bacteria, wherein the composition has a solids content of about 50% or above, to form an admixture;
- b) separating out at least a portion of the hydrocarbons from the admixture;
- and
- c) recovering at least a portion of the composition from the admixture remaining after step b) for further processing, re-use, or disposal of the composition.
