- 摘要：作为重要的基本有机化工产品，醋酸牵动着下游化工产业的发展，开展醋酸市场分析和技术跟踪研究有助于推动醋酸行业的高质量发展。文中分析了国内醋酸市场情况，醋酸的年生产量和年消费量双双突破千万吨级，华东、华北和华中地区醋酸产能较为集中，14家产能超过50×104 t/a生产企业总产能约占全国的82.7%。介绍了国外甲醇羰基化制醋酸技术发展历程，比较了 5种甲醇羰基化制醋酸的工艺特点，Celanese AO Plus工艺和 BP Cativa工艺在提升催化剂效率和降低公用工程消耗方面优势明显。整理了国内企业和研发机构优化甲醇羰基化制醋酸工艺的积极探索，比如催化优化、少水工艺、强化传质等新技术，有助于醋酸行业向绿色低碳发展。
Abstract: Acetic acid, as an important basic organic chemical product, exerts a crucial influence on the development of downstreamchemical industries. The study on conducting market analysis and technical tracking research of acetic acid is conducive topromoting the high-quality development of the acetic acid industry.The domestic acetic acid market was analyzed in this paper.Both the annual output and annual consumption of acetic acid have exceeded 10 million tons. The production capacity of acetic acidis relatively concentrated in East China, North China and Central China. The total production capacity of 14 enterprises with anannual capacity of over 500,000 tons accounts for about 82.7% of the national total. The development history of overseas methanolcarbonylation technology to acetic acid was introduced, and the process characteristics of five methanol carbonylation processes foracetic acid synthesis were compared. The obvious advantages in improving catalyst efficiency and reducing utility consumption isconcentrated in Celanese AO Plus process and BP Cativa process. In addition, the active explorations such as new technologiesincluding catalyst optimization, low-water process, mass transfer enhancement and so on were sorted out by domestic enterprisesand research institutions in optimizing the methanol carbonylation process for acetic acid production, hoping to contribute to thegreen and low-carbon development of the acetic acid industry.
