Convenience and comfort... creating greater satisfaction.

NIPPON KETJEN produces a full line of high-quality catalysts. Our products undergo demanding quality control all the way from development to production, shipment and supply to the customer. Not content simply with high quality, we have created a variety of hydroprocessing catalysts that respond to the individual needs of customers. NIPPON KETJEN has also actively promoted product development with emphasis on constantly anticipating customer needs.


Quality management

NIPPON KETJEN employs leading-edge catalyst technology in production of hydroprocessing catalysts. There are demanding quality control systems at all stages of production and in all areas of operations. In order to achieve continuous improvements in the areas of safety, management, cost-control and distribution, we conduct thorough self-checks on all our operations. The various quality circles and activities to provide ideas for improvement are being promptly implemented. We have also created a working environment characterized by personal interest and responsibility for the impact each role has on the company's result. This “quality consciousness”, an element that cannot be achieved by devices and computers alone, is one of the major resources of NIPPON KETJEN.
