(TU Delft Sanitary Engineering) Date 2022 Abstract Oil palm empty fruit bunch (OPEFB) is an abundant waste that is commonly incinerated, causing environmental pollution. In this study, an alternative waste management approach was investigated to produce value-added syngas from OPEFB using solar steam gasification. The three operating variables were temperature (1100–1300 °C), H2O/OPEFB molar ratio (1.7–2.9), and OPEFB flowrate (0.8–1.8 g/min). Central composite design (CCD) was conducted to investigate and optimise the effects of these operating variables on H2/CO molar ratio and solar to fuel energy conversion efficiency (ηsolar to fuel). The findings revealed that all investigated operating variables were significant. Experimentally, the highest H2/CO molar ratio (1.6) was obtained at 1300 °C, H2O/OPEFB molar ratio of 2.9, and OPEFB flowrate of 1.8 g/min, with a high carbon conversion reaching 95.1%. Results from CCD analysis showed that a higher H2/CO molar ratio (above 1.8) could be reached at 1200 °C, H2O/OPEFB molar ratio of ≥3.0, and OPEFB flowrate of ≥2.0 g/min. The maximum ηsolar to fuel of 19.6% was achieved at 1200 °C, H2O/OPEFB molar ratio of 1.3, and OPEFB flowrate of 1.3 g/min, whereby a favourable energy upgrade factor (1.2) was achieved. The statistical model showed adequacy to predict H2/CO molar ratio.
