摘　　要：以费托合成装置副产的混醇为研究对象,借助固体悬浮物含量测定、电感耦合等离子光谱分析、激光粒度分布仪、气质联用等表征手段,对其组分进行了定性和定量分析,研究了混醇中固体杂质、有机杂质、金属离子、酸类组分等有害物质的去除方法。结果表明,优化后的混醇处理方案包括过滤、金属离子去除和酸类组分去除3个步骤,使用该方案处理后的混醇可以满足MTP反应的进料要求。Qualitative and quantitative analysis was made on the compositions of the mixed alcohol by-product of the Fischer-Tropsch synthesis unit by the characterization methods of determination of suspended solids content,ICP,laser particle size distribution analyzer,GC-MS and so on.The removal methods of solid impurities,organic impurities,metal ions,acidic components and other harmful substances in the mixed alcohols were studied.The results showed that the optimized mixed alcohol treatment scheme included three steps:filtration,metal ion removal and acidic component removal,and the mixed alcohol after such a treatment could meet the feed requirements of the MTP reaction.
