Box-Behnkenof response surface methodology was applied for the experimental design. Under the optimal condition: 1110W of power, 3.5m of reaction time, 2% of the amount of the absorbent, the maximum biofuel content from microwave pyrolysis of water hyacinth was 20.17%. Introduction Water hyacinth, as waste biomass, can potentially be used to prepare bio-oil and biochar and address pressing issues of energy shortage and serious environmental pollution through microwave pyrolysis [1-3]. Effectively converting water hyacinth biomass into renewable bio-oil, ethanol, hydrogen, and methane biofuels is one of the interesting and promising solutions to the said problem [4-6]. Biomass pyrolysis bio-oil preparation is an important method of biomass energy conversion, In fact, all the investigations using full factorial design for microwave pyrolysis water hyacinth producing bio-oil are tedious and response surface methodology(RSM), which is a collection of statistical and mathematical techniques, has been proved to be an effective way for the desired purpose.[7-9] Most of studies were concerned with the extraction of oil using microwave pyrolysis.
