2009年世界己二酸产能达350万吨/年,同比增长15.5%,当年消费量约290万吨,今后几年,全球己二酸市场需求有望以年均约2.5%的速度增长,到2012年总消费量将达到约320万吨,届时产能将超过380万吨/年,产品供应充足,亚洲是需求增长最快的地区,且其增长动力主要来自中国。2009年中国己二酸产能为60,5万吨/年,当年表观消费量达50万吨,国民经济的快速发展将使己二酸需求快速增长,预计2012年需求量约达到65万吨,而届时生产能力将达到91.5万吨/年,我国己二酸的自给率将有较大提高,并且供应过剩,因而今后市场竞争将进一步加剧。 In 2009, the world’s adipic acid production capacity reached 3.5 million tons per year, an increase of 15.5% year-on-year, and the consumption was about 2.9 million tons. In the next few years, the global adipic acid market demand is expected to grow at an average annual rate of approximately 2.5% by 2012. The total annual consumption will reach approximately 3.2 million tons. At that time, the production capacity will exceed 3.8 million tons per year, and the supply of products will be sufficient. Asia is the region with the fastest growth in demand, and its growth is mainly driven by China. In 2009, the production capacity of adipic acid in China was 6,000,500 tons/year, and the apparent consumption amounted to 500,000 tons. The rapid development of the national economy will lead to a rapid increase in the demand for adipic acid. The estimated demand in 2012 is approximately 650,000 tons. , And when the production capacity will reach 915,000 tons / year, China’s self-sufficiency rate of adipic acid will be greatly improved, and the supply surplus, so the future market competition will further intensify.
