Abstract:
The application of cellulosic biomass makes it possible to avoid problems of utilizing food resources in the biofuel technology and to enhance the competitiveness of biofuels by using cheap and available raw materials. The development of technologies for lignocellulose-to-biofuel conversion by fermentolysis methods is connected with employing a complex processing operation to release cellulose and improve its surface bioaccessibility. A versatile thermobaric setup has been developed to implement pretreatments conforming to the principles of environmental safety, effective delignification, and related costs’ reduction. Miscanthus sinensis Andersson was subjected to hydrotropic pulping with an aqueous solution of sod ium benzoate under autoclaving conditions. This involves treatment at 180 °C under excess pressure of 1.0 MP a and isolation of cellulose from the reaction mass. The resultant fibrous residue was hydrolyzed using commercial enzymes. The fibrous fractions were eventually produced in a high yield of 43-46% on a feedstock basis, the content of α-cellulose and acid-insoluble lignin being 85-86% and 7.0-7.6%, respectively. The substrate was found to have a sat isfactory reactivity to fermentolysis, the yield of reducing agents being 65.5% of the weight in 72 h hydrolysis.
