Abstract

The potential of palm empty fruit bunch (EFB) ash as a base catalyst for hydrogen production from
hydrolysis of water with Aluminium has been inverstigated by using a simple hand-made reactor. This study was preceded by using conventional bases, NaOH and KOH, then compared with the use of K₂CO₃ and EFB ash as catalysts. The catalyst was prepared by ashing the EFB at 600^oC for 2 h. Characterization of catalyst was conducted by X-Ray Diffraction (XRD) and Atomic Absorption Spectroscopy (AAS) methods. EFB ash contains potassium in K2CO3 and KCl form, with total potassium of 29.3% by weight. Water hydrolysis was carried out by reacting 0.01 g of Aluminum with various concentrations of KOH, NaOH, K₂CO₃ solutions, and EFB ash filtrates. The increasing of catalysts concentration caused the enhancement of hydrogen gas produced. The highest conversion of hydrolysis reaction was obtained by the application of KOH as a catalyst. The utilization of NaOH leads the reaction faster. K₂CO₃ and EFB ash filtrate also can be used to produce hydrogen with a high enough quantity but slower.
