Chinese Academy of Sciences develops non-food bioethanol technology

Sinochem New Network News Recently, two non-food biomass feedstock fuel ethanol technologies of the Chinese Academy of Sciences Institute of Process Engineering - the process of comprehensive utilization of steam explosion pueraria and its use of equipment, steam explosion of sweet potato direct solid state fermentation production of fuel ethanol were obtained in Australia And Indonesia International Patent Licensing.

These two technologies are key technologies for the utilization of non-food starch raw materials such as Pueraria. For key technologies such as the use of components (starch) in the process of energy utilization of non-food starchy raw materials such as Pueraria lobata, sweet potato, etc., the use of single, starch-based raw materials for the fermentation of ethanol, high energy consumption in cooking processes, and serious pollution, researchers have innovated. Combining steam explosion pretreatment with continuous coupled solid-state fermentation technology, a low-pressure, short-time (0.6-1.0 MPa, 2 to 4 minutes) process replaces the traditional long-time high-temperature cooking process (90°C to 120°C, 30- 120 minutes) A ​​new process of continuous coupled solid-state fermentation to produce ethanol, and extracting flavonoids from pueraria roots from fermentation residues to prepare protein feeds, etc., has enabled the classification and conversion of non-food starchy raw material components and integrated clean and efficient use.
