It is believed that the lignocellulosic biomass (LB) is mainly composed by three
pseudo components, i.e. pseudo hemicelluloses, cellulose, lignin. In the famous
three-parallel-reaction (TPR), each of pseudo component decompose independently
and generate char and volatiles (includes tar and gas) during pyrolysis (Eq.(R-1)).
And the mass (m) loss rate equation of TPR model is represented as (Cai et al., 2013):
ci is contributed faction of i-th component to the overall mass loss rate, and i=1, 2, 3
refers to pseudo hemicelluloses (P-HC), pseudo cellulose (P-CL), pseudo lignin
