First of all, in theoretical derivation, the materials are simplified into single component:
Biomass materials with an initial weight m0 degrades under the condition of temperature rise.
At a certain time t, the substrate weights mt, and accord to Arrhenius law, the degradation rate is given by (1) Where (2) α is transformation ratio and is defined as (3) is the weight of materials at any temperature in the limited range; is weight of residual at the final temperature; is the initial weight of materials.
