Present study of the biofuel potential of rice straw (RS) waste biomass materials. The average activation energy of rice straw was determined from KAS, FWO and Starink are 84.11, 89.62 and 84.52 kJ/mol, respectively. The characterized rice straw biomass has been tested for biogas potential under co-digestion mode of rice straw and cow dung in ratio 1/2. The maximum 339 ml/g Vs of biogas has been recorded in 35 days with CH concentration of 58.3%. The rest being CO as well as HS has been found in trace amounts with observed 85% total solids and 74% volatile solids, present in rice straw.
本研究探讨了水稻秸秆（RS）等生物质废料作为生物燃料的潜力。通过 KAS、FWO 和 Starink 方法测定的水稻秸秆的平均活化能分别为 84.11、89.62 和 84.52kJ/mol。对水稻秸秆生物质进行了特性分析，并在 1/2 比例的水稻秸秆和牛粪共消化模式下测试了其沼气潜力。在 35 天内，沼气产量最高达到 339ml/gVS，CH4 浓度为 58.3%。其余为 CO 和痕量的 H2S，水稻秸秆中的总固体含量为 85%，挥发性固体含量为 74%。
