国内环氧丙烷市场分析及技术进展

分析了国内环氧丙烷(PO)的生产和消费状况,介绍了原料丙烯的影响及其在聚氨酯、聚碳酸酯和二氧化碳基可降解塑料等下游产业链的应用前景,综述了工业生产上氯醇法、共氧化法和过氧化物直接氧化(HPPO)法制备PO的技术特点及发展趋势。指出PO市场具有较大的发展空间;HPPO法安全环保、清洁高效,是未来PO产业发展的方向。针对当前PO产业存在的区位产能过于集中,单体生产规模偏小、落后技术所占比例高等问题,提出:结合中西部地区原料丙烯供给和对PO消费需求,合理调整产业布局;推广国产化HPPO工艺,加快实施产业升级;构建上下游一体化产业链,形成规模化生产,实现效益最大化等发展建议。

Market analysis and technology progress of domestic propylene oxide

The supply-demand status and application prospect in downstream products were analyzed and the technical features and advance in PO production processes were summarized. There would be sufficient space for development of PO market. The clean,cost-effective,environment-friendly HPPO process represents the future trend. Some development proposals on industrial layout adjustment and upgrading PO industry were put forward to address the existing problems of concentrated production capacity,inefficient small-scale production,and high proportion of backward technology,such as adjusting capacity distribution with respect to rising PO demand in the midwest region of China,promoting localized HPPO process to accelerate industry upgrading,building supply chain integration and forming large-scale production to realize benefit maximization. Such proposals could provide guidance for development of PO industry.
