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:
Disclosed is a new composition of matter comprising a polymeric material of photosynthetic origin having embedded therein small particles of an inorganic material. The composition of matter is particularly suitable for use in processes whereby the polymeric material is converted to fuels in liquid or gas form, and/or to the valuable specialty chemicals. The polymeric material comprises biomass. More specifically, the polymeric material comprises cellulose and at least one of hemicellulose and lignin.

A process is disclosed for converting Tar Sand to fuels and/or valuable chemicais. The process comprises the steps of a) activating Tar Sand to make it more susceptible to conversion; c) partially converting the Tar Sand to a solubilized material; and d) subjecting the unconverted Tar Sand to a second conversion step. The process optionally comprises a step b) of adding a solvent to the activated Tar Sand. In a preferred embodiment the solubilized Tar Sand obtained in step c) is removed before the unconverted Tar Sand is subjected to step d).
摘要:
A process is disclosed for converting cellulose to nanocellulose. The process comprises dissolving a cellulose feedstock in an inorganic molten salt solvent medium. The solvent medium is substantially proton free. The solvent medium may contain a proton scavenger. The process is carried out at relatively low temperatures, and requires little input of mechanical energy.
摘要:
A process for the separation of a monosaccharide from an aqueous solution comprising the monosaccharide, in particular a hydrolysate of a polysaccharide containing biomass, characterized in that a) the solution comprises one or more salts or mineral acids, b) the solution is contacted with a zeolite adsorbent preferably of BEA zeotype for adsorbing the monosaccharide on the zeolite, c) the zeolite with the adsorbed monosaccharide is separated from the solution, d) the monosaccharide is separated from the zeolite absorbent. The process in a chromatographic process, in particular SMB, produces relatively highly concentrated and pure monosaccharide solution in water.
摘要:
A process for converting cellulose to glucose, said process comprising the steps of: providing a hydrated molten salt; contacting the hydrated molten salt with a cellulose-containing material to form dissolved glucose; removing the dissolved glucose from the hydrated molten salt.
摘要:
A process is disclosed for converting polysaccharides to platform chemicals. The process comprises dissolving the polysaccharides in a inorganic molten salt hydrate, converting the polysaccharides to monosaccharides, and converting the monosaccharides to platform chemicals that are easily separable from the inorganic molten salt hydrate.Preferably the polysaccharides are provided in the form of a biomass, more preferably a ligno-cellulosic biomass.
摘要:
A process is disclosed for converting lipid-containing biomass to a liquid fuel and/or platform chemicals.The process comprises the steps of dissolving the lipid-containing biomass in an ionic liquid, whereby a lipid phase and a hydrophilic phase are formed. The lipid phase contains primarily triglycerides, which can be converted to biodiesel by transesterification to, e.g., methyl esters. The hydrophilic phase comprises dissolved biopolymers, such as cellulose, hemicellulose, and protein. The biopolymers are converted in situ to compounds that are insoluble in the ionic liquid.The ionic liquid is regenerated by removing insolubles, such as lignin, ash from the biomass, and water.
摘要:
A process for the conversion of a cellulose containing feed comprising the steps of: contacting the cellulose containing feed with a molten salt hydrate and mildly hydrolyzing the cellulose to form a solution of partially hydrolized cellulose, separating one or more components of the partially hydrolyzed cellulose from the solution, converting the separated one or more components of the partially hydrolyzed cellulose in a thermo-catalytic process.
摘要:
A process is disclosed for converting a polysaccharide-containing biomass material to platform chemicals.The process comprises dissolving the polysaccharides in an inorganic molten salt hydrate, converting the polysaccharides to monosaccharides, and converting the monosaccharides to derivatized (di) anhydro sugars that are easily separable from the inorganic molten salt hydrate.The derivatized (di) anhydro sugars are useful as fuel additives and fuel substitutes.
