PROSES HIDROLISIS SAMPAH ORGANIK MENJADI GULA DENGAN KATALIS ASAM KLORIDA
Abstract
Hydrolysis is one of the most important stages of bioethanol production made from organic waste. Hydrolysis with dilute hydrochloric acid concentration was varied from 0.25-1% with a temperature of 120-180oC and time of 15-120 minutes. Reactant ratio 1:6 between organic waste and dilute hydrochloric acid for every stage hydrolysis was reacted in a batch reactor system. The sugars concentrations in the hydrolyzate were then analyzed by Nelson-Somogyi method. The results showed that the best conditions for hydrolysis was found at temperature of 120oC, catalyst concentration of 0.75%, time of 30 minutes and the pressure of 4 bar with the sugar concentration of 29.34 mg/mL and the yield of 13.09%.
Key word : hydrochloride acid , hydrolysis, sugar concentration, yield
