我国丁二烯产能2011年底达2.464 Mt。2013年,齐翔腾达年产0.10 Mt氧化脱氢制丁二烯项目已投料开车产出合格产品;中国石油在四川新建的0.15 Mt/a丁二烯装置、武汉0.80 Mt/a乙烯项目配套新建的0.12 Mt/a丁二烯、扬巴公司0.12 Mt/a丁二烯装置将陆续开车。预计2013年我国丁二烯产能增加0.90 Mt,而即将投产或已开工建设的下游装置对丁二烯的需求量将达到1.469 Mt/a,需求增量是供给增量的161%。尽管未来几年,新增产能的释放能够在一定程度 China’s butadiene production capacity by the end of 2011 reached 2.464 Mt. In 2013, Qixiang Tengda’s 0.10 Mt Oxidative Dehydrogenation to butadiene project was commissioned to produce qualified products by car. The 0.15 Mt / a butadiene plant newly built by PetroChina in Sichuan and the 0.80 Mt / a ethylene project in Wuhan were newly built Of 0.12 Mt / a butadiene and 0.12 Mt / a butadiene unit of Yamba will drive one after another. It is estimated that the butadiene production capacity in China will increase by 0.90 Mt in 2013, while the demand for butadiene to be put into operation or the downstream facilities under construction will reach 1.469 Mt / a and the demand increment is 161% of the increment of supply. Although in the next few years, the release of new capacity can be a certain extent
