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.
Abstract:
Processes for making a catalytic system and catalytic systems for converting solid biomass into fuel or specialty chemical products, or for upgrading bio-oils are described. The catalyst system may comprise a non-zeolitic matrix with a hierarchical pore structure ranging from 300 to about 104 Angstrom pore size, a zeolite, such as MFI-type or IM-5 zeolite, and a binder.
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 and system for separating a light fraction, a bio-distillate fraction, and a heavy fraction from a bio-oil, and for producing a renewable distillate including at least in part the bio-distillate fraction and a stabilizing additive, is provided. In addition, a process and system is provided for upgrading a bio-oil by use of a diluent and/or a recycle stream from the upgrading process to reduce fouling in upgrading equipment, such as a preheater and a hydrodeoxygenation unit.
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:
A process for preparing a renewable biofuel consists of subjecting a bio-oil mixture to deoxygenation in a hydrotreater and then separating hydrocarbon fractions from the deoxygenated product to form the biofuel. The bio-oil mixture contains a biooil feedstream and a treated bio-oil feed. The treated bio-oil feed is a stream from which undesirable heavy materials and solid materials have been removed.
Abstract:
Disclosed is a process/system for the fractionation of bio-oil, produced from the thermo-catalytic conversion of biomass, into boiling point fractions. The fractionation of the bio-oil is performed using molecular distillation under conditions which minimize the thermal stress to the bio-oil and fractions obtained therefrom.
Abstract:
Processes for making a catalytic system and catalytic systems for converting solid biomass into fuel of specialty chemical products are described. The catalyst system may comprise a non-zeolitic matrix and an in situ grown zeolite, such as MFI-type zeolite, with a meso-micro hierarchical pore structure. In some embodiments, the non-zeolitic matrix has a meso-macro hierarchical pore structure.
Abstract:
Naphtha compositions with enhanced reformability are provided. The naphtha compositions can be derived from biomass, can exhibit improved N + 2A values, and can be used as a reformer feedstock with little or no processing.
Abstract:
More stable and valuable bio-oil produced from biomasses are provided. More specifically, more stable and valuable bio-oil useful as heating oil is provided. Particularly, various embodiments of the present invention provide for a bio-oil having sufficient heating value and stability to be useful as heating oil without the need to hydrotreat the bio-oil or use a similar deoxygenating process.
