  • Publication number: 20210246474
    Abstract: The present invention relates to a process for continuous production of second-generation ethanol from lignocellulosic biomass via continuous simultaneous saccharification and co-fermentation (SSCF) process, wherein the process includes a first fermentor vessel for selectively fermenting C5 sugars and then Continuous transferring the fermented biomass to a second fermentor vessel for hydrolyzing the fermented biomass and then Continuous transferring the hydrolysate to a third fermentor vessel for selectively fermenting C6 sugars to obtain ethanol. Overall, the ethanol yield achieved was up to 70% for both C5 and C6 sugars from pretreated biomass; and C5 utilization exceeded 95% after SSCF.

  • Publication number: 20210047661
    Abstract: The present invention relates to a process for production of ethanol from lignocellulosic biomass via modified simultaneous saccharification and co-fermentation (SSCF), wherein the process includes transferring or recirculation of residual biomass from a first batch of SSCF to a second batch of SSCF at the time of enzymatic hydrolysis and then transferring the residual biomass in part or completely from the second batch of SSCF to a third batch of SSCF process to its hydrolysis reaction step. Overall, the average ethanol yield from three conjugative batch of SSCF is 5.06% higher compare to the single batch of SSCF without adding any additional enzyme, and hydrolysis time.

  • Publication number: 20190276857
    Abstract: The present invention relates to a process for production of ethanol from lignocellulosic biomass via modified simultaneous saccharification and co-fermentation (SSCF). In the present invention, enzymatic hydrolysis is preceded by mainly C5 sugar fermentation and low enzymatic hydrolysis and succeeds by mainly C6 sugar fermentation at different temperature and duration. This resulted into reduction in enzyme dosage and process time with increase in ethanol yield from acid pretreated biomass.

  • Publication number: 20050022445
    Abstract: The present invention relates a surfactant composition for use as an emulsifier in water blended fuel mtixture. The said composition includes ethoxylate of cashew nut shell liquid. In addition ethoxylate of cashew nut shell liquid, the said composition comprises a co-surfactant having a hydrophilic lipophilic balance in the range of 4 to 12 and a polymeric dispersant. The water blended fuel mixture using emulsifers of the present invention, overcome some of the shortcomings of the previously known emulsions. The ethoxylate of cashew nut shell liquid is of the formula (I).
