The economic feasibility of the process of converting biomass into carbon black through a catalytic pyrolysis process will be improved if it produces a high-quality biochar byproduct. Low ash content is an indicator of its high-quality biochar. Oil palm fronds are biomass from oil palm plantations, which are massive in number but have not been utilized properly. This study investigates the pre-treatment method of oil palm fronds so that when used as a raw material for the catalytic pyrolysis process, it can produce biochar with a low ash content that meets the requirements as a raw material for making carbon black. In this study, the fronds were washed with water, acetic acid, citric acid and nitric acid with acid concentrations of 3%, 5% and 10%. The result shows that the one-step acetic acid leaching method is a promising method for reducing ash content. The optimum acetic acid leaching method is using acetic acid 3% as the leaching agent, which can reduce ash content to 0.6 wt.%. And, due to its added value that can be recycled from liquid catalytic pyrolysis products, acetic acid is more recommended to be used as an acid solution for the leaching method than citric acid and nitric acid.
