Patent number: 9297366Abstract: A system or methodology for converting thermal energy obtained from solar thermal, photovoltaic, geothermal or industrial waste heat into electrical power is disclosed. The energy efficient way of transferring two steams of liquid solutions containing different concentrations of ionic species is disclosed. The combination of thermal gradient in addition to concentration gradient to improve efficiency, reduce or avoid fouling is disclosed. This invention describes a method of efficient ion migration from concentrated stream to dilute stream thereby improving DC power generation process. The utilization of solar thermal energy from solar collector or concentrating photovoltaic (CPV) generator system or solar thermal power generation (CSP) system provides the additional driving force for ions transport from concentrated stream to dilute stream, apart from the concentration grading to generating power.Type: GrantFiled: September 3, 2013Date of Patent: March 29, 2016Assignees: SuGanit Systems Inc., The University of ToledoInventors: Praveen Paripati, Rahul Patil, Gary Glenn Lipscomb, Mahabala Adiga

Publication number: 20140342420Abstract: The present invention provides a method for the production of an alkanol from biomass. The method for producing an alkanol, including n-butanol, comprises fermenting a carbohydrate to produce a diacid and converting the diacid into an alkanol by solution chemistry or solid phase chemistry. The carbohydrate may be derived or extracted from a lignocellulose, an algae, a grain, or a starch containing root.Type: ApplicationFiled: August 22, 2012Publication date: November 20, 2014Applicant: SUGANIT SYSTEMS, INC.Inventors: Guneet Kumar, Praveen Paripati

Patent number: 8546109Abstract: The present invention relates to a method for lignocellulosic conversion to sugar using an ionic liquid pretreatment for the saccharification of lignocellulosic biomass. Thus, cellulose, hemicellulose, when hydrolyzed into their sugars, can be converted to ethanol fuel through well-established fermentation technologies. These sugars also form the feedstocks for production of a variety of chemical and polymers. The complex structure of the biomass required pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars.Type: GrantFiled: September 1, 2011Date of Patent: October 1, 2013Assignees: Suganit Systems, Inc., The University of ToledoInventors: Sasidhar Varanasi, Constance Ann Schall, Anantharam Prasad Dadi, Jared Anderson, Kripa Rao, Praveen Paripati, Guneet Kumar

Publication number: 20120193046Abstract: A method for lignocellulose conversion to sugar with improvements in yield and rate of sugar production has been developed by using ionic liquid pretreatment. This new pretreatment strategy substantially improves the efficiency (in terms of yield and reaction rates) of saccharification of lignocellulosic biomass. Cellulose and hemicellulose, when hydrolyzed into their sugars, can be converted into ethanol fuel through well established fermentation technologies. These sugars also form the feedstocks for production of variety of chemicals and polymers. The complex structure of biomass requires proper pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars. Current pretreatment approaches suffer from slow reaction rates of cellulose hydrolysis (by using the enzyme cellulase) and low yields.Type: ApplicationFiled: September 1, 2011Publication date: August 2, 2012Applicants: Suganit Systems, Inc., The University of ToledoInventors: Sasidhar VARANASI, Constance Ann Schall, Anantharam Prasad Dadi, Jared Anderson, Kripa Rao, Praveen Paripati, Guneet Kumar
