天然气经甲醇制烯烃技术的进展及经济分析（Progress and economic analysis of methanol production by methanol from natural gas） The progress of natural gas and methanol to olefins technology economic analysis Tian Feng Yang Ying Yang Shiyuan (Institute of PetroChina Co Ltd, Lanzhou petrochemical 730060) Abstract: in the process of preparing olefin gas in natural gas, methanol to olefins (NG-MTO) technology is the most with industrialization technology. This paper focuses on the latest development of MTO technology from the aspects of process and catalyst are reviewed, analyzed the technology and economy, the results show that the MTO technology is feasible, economic, the lower the price of natural gas more competitive, such as natural gas price of $1 / million Btu, competitiveness the larger, and finally gives some suggestions on the development of MTO technology. Key words: natural gas methanol olefin MTO Olefin as the basic organic chemical raw materials, has a very important role in modern petroleum and chemical industry. In recent years, due to the continuing shortage of oil resources and the sustainable development strategy and technical route of many oil companies in the world are committed to the development of non oil resources synthesis low carbon olefins, and made some significant progress from [1 to 2]. Using natural gas as a method for producing olefin raw material has three kinds: methanol (MTO) and fees - Tropsch process (F-T) and methane oxidation coupling method (OCM). With the start of Chinas west east gas pipeline project, some progress has also been made for the use of natural gas chemical industry. Chinas Inner Mongolia Yihua group and the German EUB Group signed a natural gas chemical industry development cooperation agreement, plans to build the scale of 600 kt/a natural gas by methanol to olefins in Inner Mongolia city Erdos (NG - MTO) device, the construction period is 3 years. After the completion of the project, will become the worlds production by [3] the largest
