2018	Microwave pyrolysis of water Hyacinth for biochar production using Taguchi method	Int J Eng Technol
The fast microwave assisted pyrolysis (FMWAP) of water hyacinth (WH) for biochar production is investigated. Taguchi’s method was used to optimize FMWAP parameters. The effects of microwave power, temperature, microwave absorber (activated carbon) ratio, and biomass particle size on biochar yield as the response for the process, were studied. The maximum yield was achieved using the optimized conditions of microwave power-994 W; temperature-300 C; microwave absorber ratio-0.25; and biomass particle size-0.0315 mm. The reaction time was kept constant at 2 min. The analysis of Signal to Noise ratio (S/N) and variance (ANOVA) were used to identify the effect and the significance of the process parameters on biochar yield. The final results show the significance of all process parameters on biochar yield. The order of significance of these parameters are: microwave power> temperature> microwave absorber> biomass particle size. The produced biochar was analyzed by scanning electron microscopy (SEM) and Energy Dispersive X-Ray Analyzer (EDX). The WH biochar has macroporous
