摘要:
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.
摘要:
Emissions of polynuclear aromatic hydrocarbons (PAHs) from diesel engines may be reduced by blending a renewable hydrocarbon distillate with a base diesel fuel. The base diesel may be a fossil diesel fuel, a Fischer-Tropsch diesel fuel as well as a hydroprocessed biodiesel fuel or a combination thereof. The renewable hydrocarbon distillate is a fraction from hydrotreated bio-oil having a boiling point between from about 320° F. to about 700° F.
摘要:
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.
摘要:
More stable and valuable bio-oil produced from biomasses are provided. More specifically, more stable and valuable bio-oil useful as heating oil, alone or in combination with an oxygenated acyclic component, 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, alone or in combination with an oxygenated acyclic component, without the need to hydrotreat the bio-oil or use a similar deoxygenating process.
摘要:
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.
摘要:
A process and system for separating and upgrading bio-oil into renewable fuels is provided. The process comprises separating bio-oil into a light fraction and heavy fraction based on their boiling points. The heavy fraction is then subjected to hydrotreatment, while the light fraction is not subjected to hydrotreatment. At least a portion of the un-hydrotreated light fraction and at least a portion of the hydrotreated heavy fraction are blended with petroleum-derived gasoline to thereby provide a renewable gasoline, and at least a portion of the hydrotreated heavy fraction is blended with petroleum-derived diesel to thereby provide a renewable diesel.
摘要:
Disclosed is a process for the reduction of the electrical conductivity of a product mixture containing the oil and water phases resulting from the conversion of biomass to liquid products, including the at least partial breaking of any oil/water emulsion, which aids in the separation of the oil and water phases.

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. 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.
摘要:
A process is described for reducing the oxygen content of a high-oxygen feedstock. The process is particularly suitable for biomass-based feedstocks. The process comprises contacting the feedstock with carbon monoxide and/or coke in the presence of a catalyst. Conveniently, the coke may be present in the form of a deposit on the catalyst. Carbon monoxide may be generated in a regeneration step of the catalyst. The process may be carried out in conventional refinery equipment.
