20120144730 | PROCESS FOR PRODUCING HIGH QUALITY BIO-OIL IN HIGH YIELD - A process is disclosed for converting a particulate solid biomass material to a high quality bio-oil in high yield. The process comprises a pretreatment step and a pyrolysis step. The pretreatment comprises a step of at least partially demineralizing the solid biomass, and improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass. In a preferred embodiment the liquid pyrolysis product is separated into the bio-oil and an aqueous phase, and the aqueous phase is used as a solvent in the demineralization step and/or in the step of improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass. | 06-14-2012 |
20120304529 | Temperature-Optimized Conversion of Lignocellulosic Biomass - A process is disclosed for converting lignocellulosic material to liquid fuels. In the process the cellulose is dissolved in an Ionic Liquid. The conversion process may comprise pyrolysis, thermal cracking, hydrocracking, catalytic cracking, hydrotreatment, or a combination thereof. Undissolved lignin is removed from the Ionic Liquid medium, and is converted in a separate conversion process. The Ionic Liquid preferably is an inorganic molten salt hydrate. | 12-06-2012 |
20120323057 | Process for Converting Cellulose and/or Hemicellulose in a Liquid Fuel Comprising Dissolution in Ionic Liquid - A process is disclosed for converting cellulose to liquid fuels. In the process the cellulose is dissolved in an ionic Liquid medium. The conversion process may comprise pyrolysis, thermal cracking, hydrocracking, catalytic cracking, hydrotreatment, or a combination thereof. The Ionic Liquid medium preferably is an inorganic molten salt hydrate. | 12-20-2012 |
20120330074 | Simultaneous Catalytic Conversion of Cellulose and Lignin to a Liquid Fuel in an Ionic Liquid - A process is disclosed for converting lignocellulosic material to liquid fuels. In the process the cellulose is dissolved in an Ionic Liquid medium. The conversion process may comprise pyrolysis, thermal cracking, hydrocracking, catalytic cracking, hydrotreatment, or a combination thereof. The conversion reaction is carried out in the presence of lignin. The lignin is at least partially converted in the process. The Ionic Liquid medium preferably is an inorganic molten salt hydrate. | 12-27-2012 |
20130245252 | SIMULTANEOUS HYDROLYSIS AND HYDROGENATION OF CELLULOSE - A process is disclosed for conversion of cellulose in an Ionic Liquid medium. The process is characterized in that a cellulose-containing feedstock and an Ionic Liquid are mixed at a temperature below 80 ° C. The mixture is heated to a conversion temperature in the range of 80 ° C. to 220 ° C. under a hydrogen atmosphere. The presence of hydrogen during the heating step significantly reduces the formation of degradation products. | 09-19-2013 |
