Process Optimization and Economic Evaluation of Air Gasification of Saudi Arabian Date Palm Fronds for H 2-Rich Syngas Using Response Surface Methodology
Beschreibung:
The transition of energy extraction from the fossil fuel to renewable energy is a primary drive in world. In Saudi Arabia, date palm waste is abundantly available, and it is underutilized. Conversion date palm waste into energy is a major potential alternative source of bioenergy. In the current study, process optimization and economic evaluation of air gasification of date palm fronds (DPF) has been performed in downdraft gasifier for energy conversion. The impact of three process parameters temperature, air flowrate, and feedstock particle size on gas composition were investigated. The response surface methodology (RSM) was adopted for experimental design and individual and interactive effects of parameters to find their optimum values. Temperature is the most influencing factor on H2 composition varies 6-18 vol.% compared to air flowrate and feedstock particle size. A similar pattern of influencing factors is observed for the CO composition varies 8-20 vol.%. Thus, the enrichment of H2 and CO is due to the activation of endothermic reactions at elevated temperature. On the other hand, the influencing order for CO2 composition is feedstock particle size > air flowrate > temperature. The optimum conditions are temperature of 900°C, air flowrate of 1 l/min, and feedstock particle size of 6 mm, maximizing the H2 composition. Cost of syngas produced from air gasification of DPF was found SAR 4.04/kg. It is environmentally friendly alternative source of renewable energy that will helps to reduce the dependency of fossil fuel
