Sumitomo Chemical has constructed and begun operation of a pilot facility at the Sodegaura site of its Chiba Works for its new proprietary process to produce 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 commercializing this process and licensing the technology to other companies by the early 2030s.
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 distinguishing 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 industrialization of this process, while also conducting extensive marketing activities for polypropylene produced from propylene obtained through this process. The Company aims to commercialize and license this technology by the early 2030s.
