Impact of parameters on gas ratios obtained from air gasification of date palm waste

Abstract. Utilizing date palm waste as an energy source is a potential low-carbon source, especially in areas such the Middle East. This study investigates air gasification performed downdraft gasifier. The aims to analyze impact of various parameter ranges temperature 600-900 ᵒC, flow rate 1.0 4.0 l/min, and particle size <2-6> mm on gas ratios producer gas. H2/CO ratio important which increase from 0.53 0.71 with rise 600 900 ᵒC. A similar profiling other was noticed increase. H2/CO2 are found maximum at 2.5 l/min 3.0 l/min.H2/CH4 showed very steady trend up but sharp hike by increasing l/min. Larger shows lower value H2/CO, H2/CH4, due heat mass transfer diffusion compared smaller size.
