Cogon grass (Imperata cylindrica) is convertible into glucose by hydrolysis process, which usuallyrequires a catalyst. A solid acid catalyst of sulfonated carbon was used in this work. This study aimedto observe the viability of candlenut shell as carbonaceous source in solid acid catalyst production andto characterize the sulfonated carbon. The carbonization was performed at 250-550 ºC for 4 h, whilesulfonation was carried out at 100-180 ºC for 6 h. Sulfonated carbon was then characterized byH+ activity/acid density test, scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDX) and Fourier transform infrared (FTIR) spectroscopy. Sulfonated carbon was then testedas a heterogeneous catalyst for hydrolysis reaction. The reaction was performed in a stainless steelbatch reactor at 100 ºC for 6 h. Glucose formed by hydrolysis was measured by dinitrosalicylic acid(DNS) method. Results of this study suggested that sulfonated carbon derived from candlenut shellmay be used as a catalyst for cogon grass cellulose hydrolysis to produce glucose
