摘　　要：正己烷产品馏程在3.5℃左右,低于行业水平。影响产品馏程的关键因素是产品中2-甲基戊烷、3-甲基戊烷的含量,前加氢工艺路线可有效降低产品中2-甲基戊烷、3-甲基戊烷含量。对前加氢工艺与现工艺(后加氢)进行模拟研究,结果表明生产80级正己烷,前加氢工艺技术路线可将中间产品中的轻组分控制在0.5%以内,实现产品馏程控制在2.0℃以内。The distillation range of n-hexane is about 3.5 degrees centigrade,which is lower than the industry level.The content of 2-methylpentane and 3-methylpentane in the product is the key factor affecting the distillation range of the product.The pre hydrogenation process can effectively reduce the content of 2-methylpentane and 3-methylpentane in the product.The results show that the light components in intermediate products can be controlled within 0.5%and the distillation range can be controlled within 2.0 degrees centigrade if 80 grade n-hexane is produced.
