20100069626 | NANO-CATALYTIC-SOLVO-THERMAL TECHNOLOGY PLATFORM BIO-REFINERIES - Methods of making glucose and/or furfural from biomass require one or more supercritical fluids that may be used to process biomass, cellulose from the biomass, and/or xylose from the biomass. Examples of supercritical fluids for use in processing biomass include ethanol, water, and carbon dioxide at a temperature and pressure above the critical points for ethanol and carbon dioxide but at a temperature and/or pressure below that of the critical point for water. A supercritical fluid containing carbon dioxide and water may be used to convert cellulose to glucose or convert xylose to furfural. The fluid has a temperature and pressure above the critical point of carbon dioxide, but at least one of the temperature and pressure is below the critical point for water. | 03-18-2010 |
20110059316 | METHODS OF MAKING CEMENTITIOUS COMPOSITIONS AND PRODUCTS MADE THEREBY - A method of making cementitious particles using combustion synthesis is described. The method uses less energy and produces lower CO | 03-10-2011 |
20110094277 | NANO-SCALE UREA PARTICLES AND METHODS OF MAKING AND USING THE PARTICLES - Methods for synthesizing nano-urea particles are described. The methods involve using a spinning cone reactor, a nano-channel reactor, combustion synthesis or spray drying. Ammonia and carbon dioxide are used as raw materials for producing urea. The methods allow for the production of urea nanoparticles at high conversion rates. The methods allow for better control over the hydrolysis rate of the nano-urea particles. The nano-urea particles can be used as fertilizers and provide for sustained release of ammonia and its conversion to nitrates in the soil. The nano-urea particles have low volatilization rates, low moisture absorption rates and low biuret concentration. The nano-urea particles can be applied to the soil via fertigation. | 04-28-2011 |
