摘要: Abstract Lignocellulosic biomass–coal co-pyrolysis is a promising approach for greenhouse gas reduction. The thermochemical behaviors and product distributions must be understood to optimize the process. This paper examines effects of lignocellulosic biomass model components (cellulose carboxymethylcellulose sodium) on thermal behavior bituminous coal (BC) using non-isothermal thermogravimetric analysis. char surface morphology was evaluated scanning electron microscopy technology (SEM) fractal dimension A positive yield synergistic effect observed between BC CE. CMC exhibited negative pyrolysis, with yields being higher than predicted. additions CE decreased average activation energy analysis SEM images provided quantitative information pertaining morphology. BCCE (BC mixtures) dimensions were less those chars, indicating that addition promoted uniformity degree char. BCCMC CMCE displayed opposite trend.
