Biomass of green chemistry(biomass energy) 交通大學應用化學系 鄭至玉, 李耀坤 Introduction and application of biomass Why do we need so badly? Any other energy can we get? Green and renewable Biomass-to-energy calculation What else can we do with biomass? The problemPetrochemicals Scarce resource CO2 pollution Strategic and political weapon Low security of supply Cheap The solutionBiomass (ethanol and diesel) Renewable CO2 neutral Can be grown and exploited anywhere High security of supply Expensive (yet) Processing to gasoline or diesel can be combined with use as solid fuel Biomass –Supply and process chain Biomass based energy Plant oils –Biodiesel Solid biomass –Heat and electricity Fermentable sugars –Starch and cellulose for ethanol production Platform of biomass energy Platforms for biomass-to-energy Biofuel production by fermentation from biomass The steps of ethanol production by fermentation Three types of raw materials for bioethanol Ethanol fermentation Bacteria for bioenergy conversion Microbial Fuel Cell A case in Japan Burden on commercial power grid by introduction of variable natural power source PV operating results Expo site and new energy consortium Whole components of the new energy plant State of demonstrative project in nagakute Expo site Hydrolysis (Chemical) Hexoses Pentoses Lignin Fermentation Dehydrogenation Hydrolysis Hydrogenation Crystallisation Fermentation Dehydration Hydrogenation Crystallisation Hydrogenation Hydrolysis Oxidation Phenol derivatives, hydrocarbons Phenol derivatives, catechols Vanillin Yeast Furfural Polyols (Xylitol) Xylose Hydroxymethylfurfural Levulinic acid Polyols Glucose Alcohols (ethyl-, butyl, isopropyl-) Polyols (glyceral, ethylene glycol) Ketones (acetone) Acids (acetic, lactic, butyric) Yeast Detail in Hardy.ppt 善用不同生物質量的成分,調整製程方法可製備出多樣產物!!
