摘要:
A process is disclosed 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.
摘要:
Biomass particles are modified by associating the particles with carbon fibers. The carbon fibers may be coated onto the biomass particles, or may be embedded within the biomass particles. As a result of the association with carbon fibers the particles are more susceptible to conversion to bioliquid.
摘要:
A reactor and/or process is disclosed for fluidized cracking of solid particulate biomass material, including a first mixing zone where a particulate stream comprising solid particulate biomass is mixed with a lift gas and becomes fluidized, and including a second mixing zone where a heat carrier material is mixed with the fluidized solid particulate biomass material.
摘要:
A process and system for separating bio-gasoline, bio-diesel and bio-fuel oil fractions from a bio-oil, and for producing a renewable gasoline including at least in part the bio-gasoline fraction, is provided. The process comprises separating bio-oil into a bio-gasoline fraction and a heavy fraction based on their boiling points. At least a portion of the bio-gasoline fraction is directly blended with a petroleum-derived gasoline, without any prior hydrotreatment, to thereby provide a renewable gasoline composition.
摘要:
Disclosed are substantially non-carcinogenic bio oil-derived residue compositions produced from the pyrolysis or thermo catalytic conversion of biomass, and their use as solvents in the production of tires.
摘要:
Disclosed is a process for biomass conversion which includes co-processing the biomass with thermoplastic and non-thermoplastic polymer based materials in a catalytic pyrolysis reactor to convert such to liquid hydrocarbons; wherein hydrogen atoms originating with the polymer materials can remove oxygen from oxygenated hydrocarbons produced in the conversion of the biomass in the reactor.
摘要:
An improved biomass feed system and processes for transporting biomass to downstream processing locations are disclosed. The system uses a pressurized gas to assist in the transporting of the biomass to the conversion reactor.
摘要:
Disclosed are catalyst compositions including zeolite and silica components, methods of making, and processes of using in the thermo-catalytic conversion of biomass. Such disclosed methods of making include treating the zeolite with phosphorous during formation of the catalyst rather than prior to or after catalyst formation.
摘要:
Renewable fuels are produced in commercial quantities and with enhanced efficiency by integrating a bio-oil production system with a conventional petroleum refinery so that the bio-oil is co-processed with a petroleum-derived stream in the refinery. The techniques used to integrate the bio-oil production system and conventional petroleum refineries are selected based on the quality of the bio-oil and the desired product slate from the refinery.
摘要:
A process for pretreating a solid, cellulose-containing biomass material which pretreatment comprises contacting the solid biomass material with an Ionic Liquid medium under sub-solvating conditions. The pretreatment results in an opening up of the texture of the solid biomass material, while no or a limited amount of biomass material is dissolved. The Ionic Liquid medium preferably is an inorganic molten salt hydrate. The pretreated biomass material can be as a feedstock in any process that benefits from the change in texture resulting from the pretreatment.
