| 20100065128 | CELLULOSE PRETREATMENT PROCESS - A process for the production of ethanol from biomass is disclosed. The process relates to the pretreatment of corncob biomass and includes the steps of exposing corncob to steam in a reaction vessel at an elevated temperature and reaction pressure for a preselected exposure time. Volatile compounds are continuously vented during pretreatment. The reaction pressure is released for explosive decomposition of the corncob biomass into fibrous solids and condensate. The exposure is preferably carried out at a temperature of 190-210° C. and a pressure of 190 psig to 275 psig and an exposure time of 3 to 10 minutes. | 03-18-2010 |

| 20080206126 | Higher than 30% concentration lime slurries, preparation and uses thereof - The present invention relates to a composition comprising water, more than 30% w/w of calcium hydroxide, and >0.2% w/w dispersant. A process for preparing such a composition is also disclosed. The composition which can be in the form of a 45-55% concentration lime slurry is particularly useful for converting concentrated ammonium lignosulfonate into calcium lignosulfonate, for converting ammonium lignosulfonate into low sulfate calcium, potassium, sodium, or magnesium lignosulfonate and mixtures thereof, for removing soluble sulfate from concentrated sodium, potassium, ammonium or magnesium lignosulfonate or for treating a weak liquor obtained from the pulp and paper industry. | 08-28-2008 |

| 20100159552 | PROCESS FOR ALCOHOLIC FERMENTATION OF LIGNOCELLULOSIC BIOMASS - A process for the production of ethanol wherein a hydrolyzed lignocellulosic biomass is fermented in the presence of a stillage residue. The fermentation of cellulosic hydrolysates is improved by adding prior to and/or during fermentation a stillage residue side stream from a corn starch-to-ethanol process as a nutrient source for the yeast organisms used in the fermentation. Stillage residues from the grain dry mill ethanol producing process, including the whole stillage, wet cake, thin stillage, and/or syrup are added to assist as a nitrogen and nutrient source for the fermentive processes. The stillage residue is produced by any grain-to-ethanol process. | 06-24-2010 |
| 20100255554 | FED BATCH PROCESS FOR BIOCHEMICAL CONVERSION OF LIGNOCELLULOSIC BIOMASS TO ETHANOL - A method for optimization of a fed batch hydrolysis process wherein the hydrolysis time is minimized by controlling the feed addition volume and/or batch addition frequency of the prehydrolysate and optionally also the enzyme feed. The increase over time in hydrolysate consistency and volume and/or concentration of sugars released in the reactor, so that the enzymatic hydrolysis is controlled, significantly reduces the impact of cellulase feedback inhibition, especially for enzyme contents lower than 0.5%. The overall time to reach conversion of the total prehydrolysate feed is reduced significantly where the batch addition frequency is equal to one batch each time 70% to 90%, preferably 80%, conversion of the previous batch is reached in the reaction mixture. At an enzyme load of 0.3% in the reaction mixture, the optimum frequency each time 80% conversion was reached was found to be one batch every 105 minutes. | 10-07-2010 |
| 20100263814 | PRETREATMENT OF LIGNOCELLULOSIC BIOMASS THROUGH REMOVAL OF INHIBITORY COMPOUNDS - A process for the pretreatment of lignocellulosic biomass is disclosed. The process is intended for use in connection with biomass to ethanol processes and is directed in particular to an economical removal of inhibitory compounds generated in biomass pretreatment, which are inhibitory to downstream hydrolysis and fermentation steps. The process includes the steps of heating the lignocellulosic biomass with steam to a preselected temperature, at a preselected pressure and for a preselected time to hydrolyze and solubilize hemicelluloses in the biomass; explosively decomposing the biomass into fibers; and extracting from the resulting reaction mixture a liquefied portion of the lignocellulosic biomass before or after explosive decomposition. The liquefied portion is extracted to remove compounds from the lignocellulosic biomass which are inhibitory to enzymatic cellulose hydrolysis and sugar fermentation to ethanol. For improved efficiency and economy, the inhibitory compounds are not completely removed. Furthermore, xylose has been found to be a good indicator compound for the general level of inhibitory compounds in the reaction mixture and the extraction step is therefore controlled on the basis of the xylose content in the reaction mixture. In particular, the extracting step is discontinued once a dry matter (dm) content of xylose, as monomer or oligomer, in the reaction mixture of 4% to 8% (w/w dm) is achieved. This most economically balances the practical need for inhibitory compound removal with the economical need to control and preferably minimize the costs of the overall ethanol production process. | 10-21-2010 |
| 20100269990 | SEPARATION OF REACTIVE CELLULOSE FROM LIGNOCELLULOSIC BIOMASS WITH HIGH LIGNIN CONTENT - A process for separating the components of lignocellulosic biomass for the purpose of producing a pure reactive cellulose is disclosed. The process has two stages. In the first stage, the lignocellulosic biomass is pretreated with steam, with or without an acid catalyst, and then pressed, with or without the presence of an eluent, to remove hemicellulose and other impurities. In the second stage, the pretreated biomass is extracted with a solvent such as ethanol with or without acid catalysts in order to remove lignin and release a purified cellulose stream. The extracted cellulose is then rapidly decompressed to rupture the fibrous structure. The process provides a purified cellulose stream that is relatively easy to hydrolyze with enzymes and ferment to biofuels and other chemicals such as ethanol. | 10-28-2010 |
| 20100313882 | FRACTIONATION OF BIOMASS FOR CELLULOSIC ETHANOL AND CHEMICAL PRODUCTION - A process is defined for the continuous steam pretreatment and fractionation of corn cobs and low lignin lignocellulosic biomass to produce a concentrated cellulose solid stream that is sensitive to enzymatic hydrolysis. Valuable chemicals are recovered by fractionating the liquid and vapor stream composed of hydrolysis and degradation products of the hemicellulose. Cellulosic derived glucose is produced for fermentation to biofuels. A hemicellulose concentrate is recovered that can be converted to value added products including ethanol. | 12-16-2010 |

There is an apparatus including a container comprising a sunlight-resistant compartment containing a pathogen disinfectant liquid, a propellant, and an actuator coupled to a valve for opening and closing the valve, wherein opening of the valve causes the propellant to move at least a portion of the pathogen disinfectant liquid through an orifice in the container. Also disclosed are a system and method for dispersing a pathogen disinfectant liquid into the air in an indoor environment where a pathogen disinfectant liquid is dispersed into circulating air in a HVAC system to disinfect the air in the indoor environment.

| 20110303499 | Roller Bearing Having an Electric Solenoid Powered Brake - What is presented is a mechanical arm assembly with a novel roller thrust bearing. The mechanical arm assembly comprises a first arm having a first end and a second end. A first roller thrust bearing is mounted to the first end and to a ceiling. A second roller thrust bearing mounted to the second end. Each roller thrust bearing comprises a first bearing body and a second bearing body able to rotate relative to each other. Each roller thrust bearing has a solenoid powered brake comprising two brake shoes each with a high friction brake pad mounted to a hinge body affixed to the first bearing body, a brake drum mounted to the second bearing body, a tension spring pushing the brake shoes against the brake drum, and a mechanism for disengaging the brake shoes from the brake drum. The mechanism comprises a slider body with space for two pins, two ball bearings, and a plunger with sloped surfaces on one end and a mounting provision on the other. A solenoid is attached to the mounting provision. The sloped surface is shaped such that when the solenoid is activated and the solenoid moves the plunger, the sloped surface pushes the ball bearings apart which pushes against the pins apart which in turn pushes against the brake shoes thereby disengaging the brake shoes from the brake drum and permitting the first bearing body to rotate relative to the second bearing body. | 12-15-2011 |
