摘　　要：从乙烯原料多元化角度出发,对传统石化路线、煤/甲醇制烯烃路线和轻烃综合利用路线生产乙烯进行了评述。指出:乙烯原料多元化发展已成为产业发展的必然趋势;在未来一段时间内,上述3种工艺将齐头并进,但是前者仍是主流,而份额会逐渐减少;随着轻烃利用项目的不断推进,该路线将成为中国乙烯供应的主要来源之一;从目前乙烯下游产业来看,聚乙烯、乙二醇仍是拉动乙烯消费的核心领域。The process routes of traditional petrochemical,coal/methanol to olefins and light hydrocarbon comprehensive utilization to produce ethylene were summarized from the perspective of ethylene raw materials diversification.The pointed out that the diversification of ethylene raw material had become the industry′s development trend.In the future,the above three production routes would go hand in hand,the former would still be mainstream,but its share would gradually decline.With the development of light hydrocarbon utilization projects,this route would become one of the main sources of ethylene supply in China.Based on the current ethylene downstream industry,polyethylene and glycol would still be the core area that drove ethylene consumption.
