摘　　要：对利用天然气部份氧化制乙炔的尾气(CO+H_2)生产合成氨、甲醇等C_1化学品的技术路线进行了分析论证,以期提高原料的利用率和综合利用的经济效益。In the acetylene production process by partial- ly oxidizing the natural gas (CH_4),a great amount of tail gas (CO±H_2) ,which is the raw feed gas for the production of ammonia, methanol and C_1 chemicals, is produced. In the present paper, the technical routes for producing the above products by use of the tail gas are investigated for purpose of increasing the utilization ratio of the raw material and improving the economic results of comprchensive utilization.
