CNO (Crude Coconut Oil) is oil extracted from coconut flesh that is orange or brownish yellow. Usually, CNO refining process is done through bleaching process or blanching to remove color. In general, this oil blanching process using bleaching earth or bentonite as an adsorbent. In this study, bentonite was combined with biochar to improve its adsorption ability. The purpose of this research is to investigate the process of making bentonite-biochar composite from cassava peel and its application in CNO bleaching process. The variables studied in the manufacture of bentonite - biochar composite for CNO blanching process were the ratio of bentonite: biomass, and the influence of temperature on the composite manufacturing process. The maximum color removal was 99.2 %. © 2006-2018 Asian Research Publishing Network (ARPN).
