Organics Recovery From The Aqueous Phase Of Biomass Catalytic Pyrolysis, And Upgrading Therof

摘要

Disclosed is a process for recovering a water-soluble complex mixture of organic compounds from an aqueous stream through extraction and/or through contact of the aqueous stream with a sorbent or sorbents selected from the group consisting of polymeric microreticular sorbent resins, zeolite-based adsorbents, clay-based adsorbents, activated carbon-based sorbents, and mixtures thereof; and including methods to recover and upgrade the removed organic compounds.

主权项

1. A method comprising:
a) passing an aqueous stream comprising a water-soluble complex mixture of organic compounds to a removal zone A for contact with a sorbent A comprising a polymeric microreticular sorbent resin for removal of at least a portion of the water-soluble complex mixture of organic compounds from said aqueous stream forming a removed quantity A comprising water-soluble organic compounds; b) passing said aqueous stream from said removal zone A to a removal zone B for contact with a sorbent B for removal of at least a portion of the water-soluble complex mixture of organic compounds from said aqueous stream forming a removed quantity B comprising water-soluble organic compounds; c) recovering at least a portion of said removed quantity A from said removal zone A forming recovered quantity A and recovering at least a portion of said removed quantity B from said removal zone B forming recovered quantity B; d) utilizing a reactor feed comprising a component selected from the group consisting of: at least a portion of said recovered quantity A, at least a portion of said recovered quantity B, and combinations thereof, wherein said reactor feed comprises light oxygenated compounds; and e) charging said reactor feed to a basic catalyzed reactor containing a basic catalyst for conversion of said light oxygenated compounds to heavier oxygenated compounds.
