Sumitomo scales up process for producing propylene directly from ethanol

This new technology is expected to significantly contribute to the petrochemical industry’s effort to switch to alternative feedstocks, and is supported by the NEDO Green Innovation Fund. The company will accelerate its demonstration project for this process, with the aim of commercialising this process and licensing the technology to other companies by the early 2030s.
Propylene is a widely used key chemical, and currently, in Japan, it is mainly produced from naphtha, a fossil resource. Ethanol, on the other hand, can be produced from biomass such as sugarcane, corn, and non-edible materials like pulp. In recent years, there has also been substantial progress in the development of technology to enable the large scale production of ethanol from combustible waste, and its industrialisation is in sight. As the shift toward sustainable essential chemical feedstocks advances, ethanol is increasingly expected to serve as an alternative feedstock that replaces fossil resource-derived chemicals.
Sumitomo Chemical’s newly developed process enables the direct production of propylene from ethanol. Unlike other propylene production processes using ethanol, this process allows for the one-step production of the final product propylene without passing through intermediates such as ethylene. Because of this feature, the process is anticipated to reduce production costs. Moreover, it also generates hydrogen as a by-product. This is another advantage, because when bioethanol is used as a feedstock, it allows for the co-production of bio-derived hydrogen.
Going forward, Sumitomo Chemical will work to acquire the various data necessary for industrialisation of this process, while also conducting extensive marketing activities for polypropylene produced from propylene obtained through this process.
