ABSTRACT
As agricultural countries, Indonesia has a great rice husk potential. One of alternative usage of rice husk isas a raw material for producing NSMC as fuel gas adsorbent. Production of NSMC consist of 2 stepsprocess, rice husk pyrolysis to produce and activated char with KOH. NSMC is nano structured porouscarbon as storage media for fuel gas. The aim of this experiments was studying the effect of pyrolysis timeupon char characteristic. The research was conductedin a fixed bed reactor equipped with condenser ininert condition. Pyrolysis conducted with time variation (30, 45, 60, 75 minutes). Pyrolysis reachedtemperature till 6000C. Char from pyrolysis process was analyzed with FTIR and BET methods. Thisresearch showed that char contained C-O functional group on absorbs range 1300-1000/cm. From BETmethods showed that char surface area was 8,91 m2/gram. It was concluded that optimum time of pyrolysisprocess was 75 minutes.
