Thermal analysis and gasification study of spent coffee ground (SCG) pretreated with ionic liquids (ILs) is presented. Four ILs, namely, 1‐butyl‐3‐methylimidazolium chloride ([Bmim][Cl]), 1‐ethyl‐3‐methylimidazolium chloride ([Emim][Cl]), tributylmethylammonium chloride ([N₁₄₄₄][Cl]), and trihexyltetradecylphosphonium chloride ([P₆₆₆₁₄][Cl]), were investigated. The pretreatment was followed by thermogravimetric analysis. The syngas composition was computed using an equilibrium‐based steam‐O₂ gasification model developed in Aspen Plus® by varying gasifier temperature and steam/biomass ratio. All ILs reduced the ash content, enhanced the volatility as well as the higher heating value of SCG. IL pretreatment also decreased CO₂ and CH₄ contents showing environmental benefits of using ILs.

使用AspenPlus®对离子液体预处理的废咖啡渣进行热性能分析

介绍了用离子液体（IL）预处理的废咖啡渣（SCG）的热分析和气化研究。四个IL，分别是1-丁基-3-甲基咪唑鎓氯化物（[Bmim] [Cl]），1-乙基-3-甲基咪唑鎓氯化物（[Emim] [Cl]），三丁基甲基氯化铵（[N ₁₄₄₄ ] [Cl]），和三己基_十四烷基氯化chloride（[P ₆₆₆₁₄ ] [Cl]）进行了研究。预处理后进行热重分析。合成气的组成使用AspenPlus®开发的基于平衡的Steam-O ₂气化模型，通过改变气化炉温度和蒸汽/生物质比来计算。所有的离子液体均降低了灰分，提高了挥发性，并提高了SCG的发热量。IL预处理还降低了CO ₂和CH_4个内容显示了使用IL的环境效益。
