چکیده انگلیسی
Slow pyrolysis of bamboo is an important conversion pathway to produce biofuels and chemicals such as biomass-derived fertilizer precursor (biochar). In this study, evolved gas analysis during pyrolysis of bamboo was conducted by a combination of TG, FTIR and GC-MS to establish a detailed pyrolysis mechanism of bamboo biomass. The main decomposition temperature zones were 300-400â¯Â°C and it reached the maximum mass loss intensity at 350â¯Â°C based on DTG curves. The main functional groups escaped from biomass during pyrolysis were -OH, -CH2, -CH3, CO, C-O, and -COOH. The main compounds during pyrolysis of bamboo were acetic acid and 2-propenoic acid, ethenyl ester at 300â¯Â°C, 2-oxo-propanoic acid and 1-hydroxy-2-propanone at 350â¯Â°C and acetic acid and acetic acid ethenyl ester at 400â¯Â°C. Evolved gas analysis indicated that components in bamboo occurred in different temperatures and pyrolysis mechanisms and resulted in distinguishing pyrolysis product emission characteristics.
