The physical properties and hydrocarbon composition of condensed oil were analysed, and based on the analysis result, it was found that the condensed oil could be used as the main part of blended gasoline through removing colloid, adding cosolvent and octane number promoter. The experiments of selecting cosolvent and optimizing the blending program were performed. The results showed that using isopentanol and methanol as cosolvent, methyl - ten - butyl ether ( MTBE ) as octane number promoter,the blending program of 93# gasoline was V ( auxiliaries A)∶V( condensed oil) ∶V(MTBE) 3 ∶ 9 ∶ 2, where the auxiliaries A was a mixture of methanol and isopentanol with volume ratio 11∶3. The properties of blended gasoline could meet the national standard on motor gasoline.%分析了凝析油的物性及其烃类组成,通过脱除胶质、添加助溶剂和辛烷值改进剂等处理工艺,可将凝析油作为调和汽油的主成分.进行了助溶剂筛选及调和方案优化实验,结果表明,以异戊醇和甲醇作助溶剂,甲基叔丁基醚(MTBE)作辛烷值改进剂,93#汽油的调和方案为V(助剂A):V(凝析油):V(MTBE)为3:9:2,其中助剂A为甲醇与异戊醇的混合物,且V(甲醇):V(异戊醇)为11:3,其性能符合国家车用汽油的标准要求.
