The new process for cellulose ethanol is clean and efficient

Thread Content

Researchers at Iowa State University in the United States announced last week that they are developing a new thermochemical system for producing ethanol from cellulose. This system uses new low-emission burners and catalysts to produce ethanol, capable of generating both ethanol and heat energy as by-products. This technology gasifies waste grain straws, wood chips, and other biomass to produce syngas (a mixture of carbon monoxide and hydrogen). The burner can burn biomass efficiently and cleanly ； Catalysts can convert syngas directly into ethanol. The catalyst in this technology is carbon-based nanoparticles, which address the issues associated with traditional chemical catalysts, such as low ethanol yield, generation of greenhouse gases, and the need to operate under high temperature and pressure conditions. The new catalyst can operate at lower temperatures and pressures, achieving a higher ethanol yield.
