WebThe activated and functionalized biochars show great potential to be used as versatile catalysts and/or catalyst supports in biomass upgrading, which have been successfully applied in carbohydrate hydrolysis and dehydration, biodiesel production, biomass pyrolysis, gasification, and bio-oil upgrading. WebIn short, we have demonstrated the batch reproducibility of a recently developed and biomass-derived SAFACAM catalyst and extended its applications to the effective microwave-assisted acetalization of glycerol to synthesize solketal. Optimization of reaction conditions has been successfully extended to the use of microwave heating for just 10 min.
WebBiomass—renewable energy from plants and animals. Biomass is renewable organic material that comes from plants and animals. Biomass was the largest source of total annual U.S. energy consumption until the mid-1800s. Biomass continues to be an important fuel in many countries, especially for cooking and heating in developing countries. WebMechanism of catalytic gasification of biomass using Ni/Zr-MOF catalyst. The primary gas was produced from the thermal scission of chemical bonds in the individual constituents of biomass, when catalytic reforming reactions cleaved the C―C and C―H bonds of the carbohydrate backbone to produce CO and H 2 (Kunkes et al. 2008).
