• Pyrolysis Characteristics of Coal Biomass and Coal

     · The pyrolysis characteristics of two Chinese coals two biomass materials and their blends were investigated by both experimental and numerical methods. Single particles of the coal and biomass were prepared for the pyrolysis experiment through grinding and pressing while the blended particles were made by mixing the coal and biomass powder with different ratios before the pressing.
