Optimization of Slow Pyrolysis of Bamboo for Biochar Production using Taguchi’s L9 Orthogonal Array

This paper investigates the effects of three parameters (reaction temperature, feedstock particle size and nitrogen flow rate) towards solid (char) yield from pyrolysis bamboo. Three-factor, three-level Taguchi’s L9 Orthogonal Array was used as experimental design. The char at reaction temperatures 300-500°C, 100-1000 μm, rate 100-300 ml min −1 were investigated. maximum predicted based on signal-to-noise (S/N) ratio found to be 300°C 1000 μm 100 rate. Confirmation runs conducted validate prediction corresponding conditions.
