Notes to Editors

Oxford Catalysts designs and develops technology for the production of synthetic oil from both conventional fossil fuels and renewable sources such as bio-waste. The Group is focused on the emerging market for distributed smaller scale production of synthetic oil via Fischer-Tropsch ("FT") synthesis − a market that has the potential of producing as much as 25 million barrels of fuel a day.

The FT reaction is used when converting natural gas, coal or bio-mass into clean high-performance synthetic oil, processes known as GTL, CTL and BTL respectively. The Group is the recognised world leader in the design and development of high-activity catalysts and associated novel chemical reactors for the smaller scale production of synthetic oil. (The Group's reactor technology − known as microchannel process technology − is marketed under the brand name of Velocys).

Oxford Catalysts Group PLC is listed on the AIM market of the London Stock Exchange (LSE: OCG). The Group has some 80 employees with facilities near Oxford, UK and Columbus, Ohio, USA.
