Asphalt binder modifiers derived from the thermo-catalytic conversion of biomass are provided. The asphalt binder modifiers are useful as anti-stripping agents and in increasing tensile strength ratios for asphalt concrete, asphalt-containing roofing materials, and other asphalt applications.
摘要:
Liquid suspensions are disclosed comprising a suspending medium, small particles of biomass, and small particles of an inorganic material. The inorganic material stabilizes the suspension, so that it may be transported by pipeline or tank car without developing a sediment.
摘要:
A process is disclosed for making a biomass susceptible to depolymerization or liquefaction under mild conditions. The process comprises introducing into the biomass a material susceptible to the absorption of electro-magnetic radiation to form a radiation absorbent biomass. The radiation absorbent biomass is subjected to electro-magnetic radiation to form an activated biomass.
摘要:
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. The process comprises separating bio-oil into light, bio-distillate, and heavy fractions based on their boiling points. At least a portion of the bio-distillate fraction and a stabilizing additive are blended with a petroleum-derived-diesel-range stream, without any prior hydrotreatment, to thereby provide a renewable distillate composition.
摘要:
A process for producing fuel from biomass is disclosed herein. The process includes torrefying biomass material at a temperature between 80° C. to 400° C. to form particulated biomass having a mean average particle size between 1 μm and 1000 μm. The particulated biomass is mixed with a liquid hydrocarbon to form a suspension, wherein the suspension includes from 1 weight percent to 40 weight percent particulated biomass. The suspension is fed into a unit selected from the group consisting of a pyrolysis reactor, a fluid catalytic cracking unit, a delayed coker, a fluid coker, a hydroprocessing unit, and a hydrocracking unit, and then at least a portion of the particulated biomass of the suspension is converted into fuel.
摘要:
More stable and valuable bio-oil compositions produced from biomasses are provided. Particularly, various embodiments of the present invention provide for a bio-oil composition that has chemical and physical properties that make it more cost effective and useful as a fuel without having to undergo deoxygenating processes such as hydrotreating.
摘要:
A process is disclosed for fluid catalytic cracking of oxygenated hydrocarbon compounds such as glycerol and bio-oil.In the process the oxygenated hydrocarbon compounds are contacted with a fluid cracking catalyst material for a period of less than 3 seconds. In a preferred process a crude-oil derived material, such as VGO, is also contacted with the catalyst.
摘要:
A process is disclosed for converting biomass to fuels and/or valuable chemicals. The process comprises the steps of a) activating biomass to make it more susceptible to conversion; c) partially converting the biomass to a solubilized material; and d) subjecting the unconverted biomass to a second conversion step. The process optionally comprises a step b) of adding a solvent to the activated biomass. In a preferred embodiment the solubilized biomass obtained in step c) is removed before the unconverted biomass is subjected to step d).
摘要:
A method is disclosed including co-processing a biomass feedstock and a refinery feedstock in a refinery unit. The method can include producing a liquid product by catalytically cracking or hyrocracking or hydrotreating a biomass feedstock and a refinery feedstock in a refinery unit having a fluidized reactor. Catalytically cracking can include transferring hydrogen from the refinery feedstock to carbon and oxygen from the biomass feedstock. Hydrocracking or hydrotreating can include transferring hydrogen from a hydrogen source to carbon and oxygen from the biomass feedstock, and to carbon from the refinery feedstock.
