摘要: Life cycle (LC) of ethanol has been evaluated to determine the environmental and economical viability that was derived from biosyngas fermentation process (gasification-biosynthesis). Four scenarios [S1: untreated (raw), S2: treated (torrefied); S3: untreated-chemical looping gasification (CLG), S4: treated-CLG] were considered. The simulated composition used in this evaluation process. GHG emissions production cost varied 1.19 1.32 kg-CO2 e/L 0.78 0.90$/L, respectively, which found be dependent on scenarios. improved when feedstock instead feedstock. Although slightly reduced case CLG process, nominally increased because incurred by use CaO. This study revealed miscanthus is a promising for industry, even if it grown marginal land, can help abate emissions.
