Abstract:
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.
Abstract:
A process for producing renewable biofuels from biomass is provided wherein a bio-oil containing stream is hydrotreated in an integrated system which uses streams and components generated or obtained from the biomass treatment and conversion.
Abstract:
Disclosed is a method for determining properties of hydrocarbonaceous samples including a component prepared from: 1) the thermo-catalytic conversion of biomass, or 2) the pyrolytic conversion of biomass with subsequent upgrading. The determination of the property(ies) is by use of a near-infrared spectra based correlation.
Abstract:
A renewable fuel may be obtained from a bio-oil containing C3-C5 oxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C6+ oxygenates. In a second step, the stream is hydrotreated to produce C6+ hydrocarbons.

Abstract:
Spent catalyst or regenerated catalyst from a biomass conversion unit may be rejuvenated by treating at least a portion of the spent catalyst or regenerated catalyst with a treatment acid, the treatment acid comprising an inorganic acid or an organic acid or a mixture thereof.
Abstract:
A process for enhancing the conversion of biomass into a bio-oil containing liquid feed wherein the processability index, PI, of the biomass is optimized prior to introducing the biomass into the biomass conversion unit where catalytic pyrolysis of the biomass occurs. The PI is dependent on the ratio (S/G) between the S-unit population and the G-unit population of the biomass as well as the weight percent acetate, the weight percent alkaline (Group I metals), the weight percent of non-metals in the biomass of Group 15, Group 16 and Group 17 elements, the weight percent of metalloids (Group 13 and Group 14 elements), the weight percent xylan and the weight percent of alkaline earth (Group II metals) in the biomass feedstream.
