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:
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.The suspension may be used in manufacturing a bio-fuel.
摘要:
A process is disclosed for the conversion of cellulosic biomass, in particular ligno-cellulosic biomass. The process comprises heating the biomass to a conversion temperature in the range of from 200 to 500° C. in the presence of a catalyst system. The catalyst system comprises a basic functionality comprising an alkali metal component and a multivalent metal component. The catalyst system optionally further comprises an acidic component.
摘要:
A countercurrent process is disclosed for converting solid biomass material. The solid biomass material travels through a reactor system in countercurrent with hot heat carrier materials, such as particulate heat carrier material and hot gases. The solid biomass material is subjected to a first conversion at a first temperature T 1, and a second conversion at a second temperature, T 2, such that T 2>T 1. Bio-oil produced to at T 1 is not exposed to the higher temperature T 2. As a result, secondary reactions of the bio-oil components are minimized.
摘要:
The present invention relates to the conversion of solid biomass to liquid fuels and specialty chemicals. The process utilizes an activating step to make the biomass more susceptible to conversion, that is the biomass is broken down such that the components of the biomass are dissociated. Subsequently, the activated biomass undergoes a reaction to convert it to a bio-oil.
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 process is disclosed for regenerating or derivatizing cellulose. The process comprises the steps of providing a source of unrefined cellulose, and dissolving the unrefined cellulose in a molten inorganic salt.The source of unrefined cellulose may be a biomass, such as wood.The process permits the regeneration or derivatization of cellulose having a high degree of polymerization.
