Abstract
AbstractThe main purpose of this work is to optimize the effects of operating parameters on the yield of products from fast pyrolysis of four palm oil biomasses (empty fruit bunch [EFB], palm shell [PS], palm mesocarp fiber [PMF], and oil palm fronds [OPF]) in a fluidized bed reactor. Three kinetics schemes (simple, global, and advanced) were applied to predict the yield of pyrolytic products (liquid [bio‐oil], gas, and char). The results from the simulation of three kinetics schemes compared with the reported experimental data. The results from global and advanced kinetics schemes showed better prediction than simple kinetics scheme. The influence of the operating parameters such as biomass constituents, vapor residence time, reaction temperature and particle size on the fast pyrolysis of palm oil biomasses was investigated using the global kinetics scheme. Moreover, the yield of pyrolysis products was also classified using the advanced kinetics scheme. The results indicated that EFB biomass with particle size of 0.3 mm gave the maximum yield of liquid product due to its higher cellulose content compared to other palm oil biomasses (OPF, PMF, and PS) at reaction temperature of 773 K and vapor residence time of 1 s.
