NIPPON KETJEN, A Catalyst Manufacturer Aiming to Contribute to Stable Energy Supply and Environmental Conservation

Since our founding in 1970, we have been providing hydroprocessing catalysts for petroleum refining and contributing to the stable supply of energy and the conservation of the global environment as a member of the Sumitomo Metal Mining Group. During this time, in response to stricter environmental regulations and customer needs, we have worked to develop higher-performance catalysts and establish technologies for the regeneration and rejuvenation of used catalysts, promoting their reuse.

Recently, changes in social conditions and the natural environment have become more pronounced, and awareness of sustainable societies and environments is increasing. In collaboration with Ketjen Corporation, we have newly added the ReNewFine catalyst for the production of 100% hydrogenated vegetable oil (HVO) and sustainable aviation fuel (SAF) to our product portfolio to meet the diverse needs of our customers.

We will continue to respond quickly to the needs of society and our customers, striving even more to ensure the stable supply of energy and conservation of the global environment. We sincerely appreciate your continued support.
