截至2011年底,全球1,4-丁二醇的总生产能力达到199.4万吨,总消费量约为148.0万吨,预计到2015年全球总消费量将达到180.0万吨,需求量将滞后于产能增长速度。中国大陆是目前世界上最大的1,4-丁二醇生产国家,生产能力为50.4万吨/年,约占世界总生产能力的25.28%,总消费量约为36.7万吨。预计到2015年,我国1,4-丁二醇的总生产能力将超过200.0万吨,总需求量将达到约60.0万吨,生产能力将出现过剩,未来竞争将十分激烈。
As of the end of 2011, the global total production of 1,4-butanediol reached 1.94 million tons and the total consumption was about 1.48 million tons. It is estimated that the global total consumption will reach 1.8 million tons by 2015 and the demand will lag behind the production capacity Growth. China is currently the world’s largest 1,4-butanediol-producing country with a production capacity of 504,000 tons / year, accounting for 25.28% of the world’s total production capacity and a total consumption of about 367,000 tons. It is estimated that by 2015, the total production capacity of 1,4-butanediol in our country will exceed 2 million tons and the total demand will reach about 600,000 tons. There will be excess production capacity and the competition in the future will be very fierce.
