Bench-Scale Fluidized-Bed Fast Pyrolysis of Peanut Shell for Bio-Oil Production
· Wen Shi ·
Pyrolysis of peanut shell in a fluidized bed to produce bio-oil is investigated as a useful way to utilize the agriculture residues in China. The influence of reaction temperature and the flow rate of carrier gas (N2) on the pyrolysis product distribution and some characteristics of these products generated in the bench-scale fluidized-bed system developed in this study are quantified. The main components of bio-oil are classified into six categories including aldehydes, ketones, acids, esters, phenols, and alcohols that were analyzed with GC-MS. Properties of products (bio-oil, char, noncondensible gas) such as elemental analysis, moisture, heat value, kinematic viscosity, flashing point, and density, were also characterized. It was found out that the maximum yield of bio-oil, around 60% by weight, was achieved at reaction temperature at 500°C and the flow rate of N2 at 3.2 Nm3 h−1. N2 balance and total mass balance on this system were performed to demonstrate the result credibility of the experiments. Some other useful parameters based on the system were also obtained for future economic and design studies. © 2011 American Institute of Chemical Engineers Environ Prog, 2011
