摘　　要：天然气裂解生产乙炔的尾气用作生产甲醇的原料时必须转化除去其中的有害成份 ,四川维尼纶厂先后采用过部分氧化蒸汽转化法和加氢转化法两种技术。本文对这两种技术进行了比较 ,认为加氢法是一种比较好的安全、节能新技术。It is necessary for removing or transforming the harmful components in the tail gas of acetylene production by natural gas cracking when the tail gas is to be used as the feed of methanol production Two technologies have, early or late, ever been used for this aim One is the partial oxidation and steam reforming, and the other is catalytic hydrogenation A comparison between the two technologies has been made in this paper, and the late was said to be a new technology with better security and energy saving
