The objective of the present investigation was to optimize the pyrolysis condition of an abundantly available and low cost perennial grass of north-east India Saccharum ravannae L. (S. ravannae) using response surface methodology based on central composite design. Kinetic study of the biomass was conducted at four different heating rates of 10, 20, 40 and 60 °C min⁻¹ and results were interpreted by Friedman, Kissinger Akira Sunnose and Flynn-Wall-Ozawa methods. Average activation energy 151.45 kJ mol⁻¹ was used for evaluation of reaction mechanism following Criado master plot. Maximum bio-oil yield of 38.1 wt% was obtained at pyrolysis temperature of 550 °C, heating rate of 20 °C min⁻¹ and nitrogen flow rate of 226 mL min⁻¹. Study on bio-oil quality revealed higher content of hydrocarbon, antioxidant property, total phenolic content and metal chelating capacity. These opened up probable applications of S. ravannae bio-oil in different fields including fuel, food industry and biomedical domain.

本研究的目的是使用基于中央复合设计的响应面方法，优化印度东北Saccharum ravannae L.（S. ravannae）多年生草本植物的可得性和低成本。在10、20、40和60°C min ^-1的四种不同加热速率下进行了生物质的动力学研究，结果由Friedman，Kissinger Akira Sunnose和Flynn-Wall-Ozawa方法解释。使用平均活化能151.45 kJ mol ^-1评估Criado主图后的反应机理。在550°C的热解温度，20°C min ^-1的加热速率下获得38.1 wt％的最大生物油产率和氮气流速为226 mL min ^-1。对生物油品质的研究表明，碳氢化合物含量，抗氧化性能，总酚含量和金属螯合能力较高。这些打开了褐葡萄球菌生物油在不同领域的可能应用，包括燃料，食品工业和生物医学领域。
