A study on fast pyrolysis of single woody biomass particles was conducted with an aim to model the overall pyrolysis mass loss of a wood particle. Experiments were performed using a thin layer pyrolyzer. As part of the study, the kinetic parameter (pyrolysis rate constant) kp was determined through a series of tests that involves three factors - pyrolysis temperature T, initial biomass moisture content M, and grinder screen size S (which is related to particle size distribution after sieving the ground particles). An empirical correlation was then developed from the experimental data. a) For each set of values (T, M, S) shown in the table below, use Eqn. (1) to calculate kp for both the ground chip particles and the ground pellet particles. T M, S, C decimal db mm 400 0.1 3.2 400 0.1 12.7 400 0.5 3.2 400 0.5 12.7 500 0.1 3.2 500 0.1 12.7 500 0.5 3.2 500 0.5 12.7 kp = exp (aT+bM+CS+ d) Eqn (1) a b D ground chip particles 0.01 0.15 -0.003 -4.5 ground pellet particles 0.01 0.48 -0.008 -4.5 b) Comment on your results in terms of the effect of each factor on kp and rank the factors (with reasons) for their influence on this kinetic parameter.
