Publication number: 20220298532Abstract: Method for the production of ethanol from corn fibres. Invention relates to a process for the preparation of ethanol from a corn fibre containing feedstock by using a set of process steps specifically identified for the treatment of the said feedstock. It particularly relates to the use of a soaking followed by mix acid and enzyme treatment that release fermentable C5 and C6 sugars from said feedstock. It further relates to using a recombinant yeast to convert both C5 and C6 sugars to ethanol.Type: ApplicationFiled: June 8, 2020Publication date: September 22, 2022Inventors: Siddhartha Sourav PAL, Prasanna Sham PAI, Ajit Prabhakar DESHMUKH, Sandip Uttamrao NALWADE, Nilesh Ankush BORAGE, Ghanshyam Baburao DESHPANDE, Pramod Shankar KUMBHAR

Patent number: 7491855Abstract: Use of a specific combination of catalysts for the first and second steps of the process for the conversion of CHP to BPA provides high yields of BPA and low impurity yields, without a requirement for the intermediate purification steps. In the first step, CHP is cleaved in the presence of an acid treated clay such as acid treated Montmorillonite clay to produce phenol and acetone. In the second step, the phenol and acetone produced is reacted, preferably without intermediate purification, in the presence of a cation exchange resin catalyst that includes a cation exchange resin and a mercaptan or mercaptoalkanoic acid promoter to produce BPA.Type: GrantFiled: June 4, 2003Date of Patent: February 17, 2009Assignee: Sabic Innovative Plastics IP B.V.Inventors: Pramod Shankar Kumbhar, Jegadeesh Thampi, Bharat Singh, John W. Fulmer, Prashant Anil Tatake
