摘　　要：为扩大乙烯原料来源 ,在引进的烃类蒸汽热裂解评价装置上 ,对吐哈稳定轻烃进行了裂解性能评价实验。结果表明 :稳定轻烃是一种优质的裂解原料 ,在裂解温度为 880～ 890℃ ,m(汽 ) /m(油 )为0 .50～ 0 .55,停留时间约为 0 .1s时 ,乙烯收率可达 3 1 .86% ,三烯总收率为 54.0 2 %。稳定轻烃与石脑油共裂解时 ,乙烯、丙烯和丁二烯收率均接近库西石脑油。For expanding the feed source,the pyrolysis performance of natural gas liquid(NGL)from Tuha Oil Field in the introduced bench scale pyrolysis apparatus. The results showed that NGL was an excellent steaming cracking feedstock, when pyrolysis temperature was 880～ 890 ℃,mass ratio of steam/oil was 0.50～0.55 and residence time was 0.1 s,the yields of ethylene and three kinds of elefin were 31.86% and 54.02%,Respectively. NGL was used as the steaming cracking feedstock of millisecond furnace in Lanzhou Petrochemical Corporation and good economic benefits were obtained.
