%X In this work, the syngas production rate (FSyngas) of LaNiO3-catalysed steam reforming of palm oil mill effluent (POME) was optimized with respect to POME flow rate (V�POME), catalyst weight (Wcat), and particle size (dcat). With a net acidity, the synthesized LaNiO3 catalysed POME steam reforming by cracking the bulky compounds and valorising simpler intermediates into syngas. The degradation efficiencies (XP) were also evaluated by assessing wastewater parameters, viz. pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total suspended solids (TSS), and colour intensity (A). After steam reforming at 873 K, the liquid condensate has neutral pH and zero TSS. The parallel trend of FSyngas and XP verified syngas generation from degradation of POME's organics. At higher V�POME (0.05�0.09 mL/min), greater POME partial pressure promoted its steam reforming and water gas shift, which enhanced catalytic performance. Beyond optimum V�POME (0.09 mL/min), coke-forming Boudouard reaction deteriorated catalytic activity. Catalytic performance was boosted for a longer residence time at higher Wcat (0.1�0.3 g); nonetheless, it was reduced by agglomerated catalyst when Wcat > 0.3 g. Finer LaNiO3 (dcat > 74 μm) with greater surface area to volume ratio exhibited better performance; however, ultrafine LaNiO3 (dcat < 74 μm) had poor performance because of occluded pores. Remarkably, optimized POME steam reforming over LaNiO3 (T = 873 K, V�POME = 0.09 mL/min, Wcat = 0.3 g, dcat = 74�105 μm) has generated 132.47 μmoL/min of H2-rich syngas, whilst achieved 99.53 XCOD, 99.88 XA, 99.75 XBOD5, and 100 XTSS. © 2019 Hydrogen Energy Publications LLC
