Patent number: 8956836Abstract: The present invention provides a simpler and more energy efficient process for the preparation of fatty acid methyl ester (biodiesel) from sun dried whole seed capsules of Jatropha curcas integrated with value addition of seed shells, deoiled cake and crude glycerol co-product stream. More specifically, the invention relates to a method of dispensing with the need for excess methanol recovery through distillation, cost-effective resin treatment for the refining of methyl ester and utilization of co-streams for preparation of high density energy briquettes and Polyhydroxyalkanoate biodegradable polymer in efficient and cost-effective manner.Type: GrantFiled: March 29, 2010Date of Patent: February 17, 2015Assignee: Council of Scientific and Industrial ResearchInventors: Pushpito Kumar Ghosh, Sandhya Chandrika Prasad Mishra, Mahesh Ramniklal Gandhi, Sumesh Chandra Upadhyay, Parimal Paul, Pritpal Singh Anand, Kiritkumar Mangaldas Popat, Anupama Vijaykumar Shrivastav, Sanjiv Kumar Mishra, Neelam Ondhiya, Ramesh Dudabhai Maru, Gangadharan Dyal, Harshad Brahmbhatt, Vinod Boricha, Doongar Ram Chaudhary, Babulal Rebary, Krushnadevsingh Sukhdevsinh Zala

Patent number: 8741628Abstract: An energy efficient process for the preparation of marine microalgae Chlorella fatty acid methyl ester (CME) from hydrolysate of deoiled cake of Jatropha (JOCH) and crude glycerol co-product stream (GL7 and GL8) along with seawater diluted with tap water (1:2). A small part of the crude glycerol layer in case of JME is processed to recover glycerol for glycerol washing and the otherwise problematic still bottom is utilized for microbial synthesis of PHAs and the rest is utilized for Microalgal conversion of JME byproducts into CME. The remaining part of the methanol-depleted glycerol layer is utilized, along with hydrolysate of the Jatropha deoiled cake (JOCH), for single-stage Microalgal production of lipids by a marine Microalgal isolate (Chlorella sp.) without the need for any other nutrients. Waste streams from the microalgal processes can be discharged directly into agricultural fields as biofertilizer or recycled back in the mass cultivation.Type: GrantFiled: September 22, 2011Date of Patent: June 3, 2014Assignee: Council of Scientific and Industrial ResearchInventors: Pushpito Kumar Ghosh, Sandhya Chandrika Prasad Mishra, Mahesh Ramniklal Gandhi, Sumesh Chandra Upadhyay, Sanjiv Kumar Mishra, Imran Pancha, Anupama Vijaykumar Shrivastav, Deepti Jain, Bhumi Shethia, Subama Maiti, Krushnadevsinh Sukhdevsingh Zala

Patent number: 7695707Abstract: A method for preparation of iodizing agent for the use in the formulation of iodized salt that offers excellent stability of iodine in iodized salt is developed and the unrefined salt iodized with this compound was tested for its stability in presence of moisture, temperature and metal salts at higher temperature. The hydrotalcite type layered compound was used to prepare such compound and part of carbonate was substituted with iodate anion. The iodizing agent exhibited excellent stability of iodine in iodized salt.Type: GrantFiled: June 30, 2004Date of Patent: April 13, 2010Assignee: Council of Scientific and Industrial ResearchInventors: Pushpito Kumar Ghosh, Satish Hariray Mehta, Jatin Rameshchandra Chunawala, Mrunalben Vinodray Sheth, Mahesh Ramniklal Gandhi

Patent number: 6865942Abstract: The present invention relates to a novel device that enables a person to gauge the brine density in solar salt works from afar without recourse to sampling of the brine. The device—which can be considered as an improvisation over the conventional laboratory type Baume meter—an be placed directly in the salt pa. The device remains sunk, and therefore invisible, until the desired density of brine is approached. Thereafter it gradually floats up and becomes visible from afar. From appropriate markings on the rod connected to the top end of the device, it can be gauged whether the brine is yet to attain the desired density, or has attained the desired density range, or has exceeded the desired density range. The device is resistant to corrosion and able to combat extreme weather conditions prevailing in solar salt works. The control of brine density from afar helps eliminate the need for frequent sampling of brine for density measurement that would make adherence to the optimum process of salt production easier.Type: GrantFiled: March 20, 2003Date of Patent: March 15, 2005Assignee: Council of Scientific and Industrial ResearchInventors: Pushpito Kumar Ghosh, Kishor Manmohandas Majeethia, Mahesh Ramniklal Gandhi, Jamnadas Naranbhai Parmar, Ajoy Murlidhar Bhatt, Shanti Amritlal Chauhan, Puthoor Mohandas Vadakke, Abdulhamid Usmanbhai Hamidini
