Abstract:
Embodiments of methods and apparatuses for forming a low-metal biomass-derived pyrolysis oil are provided. The method comprises the steps of filtering a biomass-derived pyrolysis oil with a high flux rate filter arrangement having a flux rate of about 10 L/m2/hr or greater to form a low-solids biomass-derived pyrolysis oil. The low-solids biomass-derived pyrolysis oil is filtered with a fine filter arrangement having a pore diameter of about 50 μm or less to form an ultralow-solids biomass-derived pyrolysis oil. The ultralow-solids biomass-derived pyrolysis oil is contacted with an ion-exchange resin to remove metal ions and form the low-metal biomass-derived pyrolysis oil.

Abstract:
In a method for producing high carbon content products from biomass, a biomass oil is added to a cracking reactor vessel. The biomass oil is heated to a temperature ranging from about 100° C. to about 800° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to crack the biomass oil. Tar is separated from the cracked biomass oil. The tar is heated to a temperature ranging from about 200° C. to about 1500° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to reduce the tar to a high carbon content product containing at least about 50% carbon by weight.

Abstract:
Bio-oil from a feedstock selected from mustard family seeds, mustard family seed presscake, mustard family seed defatted presscake, and mixtures thereof. The bio-oil is produced by a method involving (1) pyrolyzing the feedstock to produce bio-oil, bio-char and non-condensable gases, (2) removing the bio-char from the bio-oil, (3) condensing the bio-oil, and (4) precipitating the bio-oil.
Abstract:

Abstract:
A computerized method of using a data processor having a memory to account for carbon flows and determine a regulatory value for a biofuel includes (i) storing, in memory, a first set of one or more carbon flow values characterizing the production and use of a biofuel, wherein the biofuel is derived from a first fraction of an agricultural biomass, (ii) storing, in memory, a second set of one or more carbon flow values characterizing the sequestration of solid phase biomass carbon, wherein the solid phase biomass carbon is derived from a second fraction of the agricultural biomass and wherein the sequestration mitigates anthropogenic greenhouse gas emission, and (iii) calculating, using the data processor, a regulatory value for the biofuel from the first and second sets of carbon flow values.
Abstract:
Mixed alcohol formulas can be used as a fuel additive in petroleum, synthetic or bio-derived gasoline, diesel fuels, jet fuel, aviation gasoline, heating oil, bunker oil, coal, petroleum coke or as a neat fuel in and of itself. The mixed alcohol formulations can also be utilized as a thinning agent to improve the transportation of heavy petroleum crude oils or bitumen produced from tar sands. The mixed alcohol formulations can contain combinations of two or more, three or more alcohols, or blend of C1-C5 alcohols, or C1-C8 alcohols or higher C1-C10 alcohols in order to boost energy content. The primary benefits of mixed alcohols are increased combustion efficiencies, improved fuel economies, reduced emissions profiles and low production costs. These improved combustion efficiencies result in increased miles per gallon of blended fuel.
