20100175309 | PROCESS FOR IMPROVED BIODIESEL FUEL - A process for preparing biodiesel having improved filterability characteristics including inducing transesterification of a triglyceride feedstock with cavitation to form an intermediate reaction product. Glycerol by product is separated from the intermediate reaction product before finishing the transesterification reaction in a pressurized reaction tank to yield a biodiesel reaction product. The biodiesel reaction product can be further purified by removing glycerol. | 07-15-2010 |
20110136194 | METHOD FOR INCREASING ETHANOL YIELD FROM GRAIN - A process for increasing ethanol yield from grain comprising mixing grain, water and enzyme to for a grain-based liquid medium. The grain-based liquid medium is passed through a cavitation device at a velocity and pressure capable of generating a cavitation activation energy of at least 0.4 kJ per kilogram of grain-based liquid medium to enhance the activity of the enzyme and increase ethanol yield. | 06-09-2011 |
20120157699 | PROCESS FOR PRODUCTION OF BIODIESEL - A multi-stage reactor system for preparing biodiesel is used to increase efficiency and yield and reduce impurities. A three-stage transesterification reaction for preparing biodiesel can include one high-shear cavitation reactor and two low-shear cavitation reactors, preferably in series, and optionally one or more separation vessels for removing waste and recycling triglyceride feedstock, catalyst and alcohol to the high-shear cavitation reactor. | 06-21-2012 |
20120181216 | METHOD FOR UPGRADING HEAVY HYDROCARBON OIL - A process for upgrading hydrocarbon oil including mixing hydrocarbon oil with hydrogen gas and heating the hydrogen-enriched hydrocarbon oil before passing the oil through a cavitation apparatus to induce hydrotreating. Hydrotreating is achieved by hydrodynamically generating hydrogen-filled cavitation bubbles and collapsing the bubbles in the hydrocarbon oil under static pressure. The hydrotreating process can increase the API gravity of the hydrocarbon oil and reduce the viscosity of the hydrocarbon oil. | 07-19-2012 |
20130062249 | METHOD FOR PROCESSING HEAVY HYDROCARBON OIL - A process for treating hydrocarbon oil including passing heated oil through a cavitation apparatus to statically induce cavitation treatment of the oil. The oil is passed through the cavitation apparatus in the absence on non-hydrocarbon oil substances such as hydrogen, water or other organic materials and solvents. The cavitation treatment process can increase the API gravity of the hydrocarbon oil and reduce the viscosity of the hydrocarbon oil. | 03-14-2013 |
20130273627 | METHOD FOR INCREASING ETHANOL YIELD FROM GRAIN - A process for increasing ethanol yield from grain that includes mixing grain, water and cavitated enzymes to form a grain-based liquid medium wherein the cavitated enzymes have increased activity and promote increased ethanol yield form the grain. The enzymes are passed individually through a cavitation apparatus at a velocity and pressure capable of generating a cavitation activation energy of at least 0.4 kJ per kilogram of liquid medium to enhance enzyme activity and increase ethanol yield. | 10-17-2013 |
20140051141 | METHOD FOR INCREASING ALCOHOL YIELD FROM GRAIN - A process for increasing alcohol yield from grain that includes adding cellulase enzymes or a mixture of cellulase enzymes to break down cellulostic feedstock, which is typically discarded. The cellulase enzymes or a mixture of cellulase enzymes may be added to a conventional alcohol production process either through a joint or separate fermentation process. | 02-20-2014 |
20150093789 | METHOD FOR ENHANCING OIL PRODUCTION FROM GRAIN - A process for increasing oil yield from grain that includes passing a grain-based liquid stream of an alcohol production process through a cavitation apparatus to apply cavitational energy to the grain-based liquid stream, wherein the cavitational energy is applied to the grain-based liquid stream prior to a distillation phase of the alcohol production process. | 04-02-2015 |
