The methanol can 1st be obtained from coal or natural gas. In the Methanol to Olefins (MTO) process, the methanol is then converted to olefins such as ethylene and propylene. The olefins can be reacted to produce polyolefins, which are used to make many plastic materials.
Worldwide, there are 3 main methanol-to-olefin technologies. All 3 are being used widely:
- MTO by UOP2
- D-MTO
- S-MTO
The successful development of a commercially applicable MTO technology needs to solve many scientific and technical problems:
- to establish a selectivity control principle for this complex reaction system through a deep understanding of the mechanisms of reaction and deactivation
- to develop an efficient catalyst through the application of new zeolitic materials and the study of interplay between synthesis method, catalyst property, and reaction performance
- to scale up the synthetic process of the catalyst with commercially available raw materials and establish standards to ensure the reliability and repeatability for large scale catalyst production
- to find out a suitable reactor type with optimal reaction conditions and explore the commercial availability
- to make a complete process flow diagram and set up a reliable reactor scale-up approach
- to integrate the knowledge obtained from reactor scale-up with existing industrial experiences to make basic design package for commercial unit
