OXFORD CATALYSTS GROUP PLC

("Oxford Catalysts" or "the Group")

Second Order for Commercial Scale FT Reactor

Oxford Catalysts Group PLC, the leading technology innovator for synthetic oil production, is pleased to announce that it has received an order for a commercial scale Fischer-Tropsch ("FT") reactor and catalyst from SGC Energia, SGPS, S.A. ("SGCE").

This is the Group's second order for a commercial FT unit, following an order from SGCE in December 2010 that was fulfilled successfully on schedule in March 2011. The units will be deployed in a facility being constructed in South America. SGCE is currently completing its plans for a second and much larger commercial plant. It expects to be in a position to proceed with the project in the second half of 2011.

Roy Lipski, CEO of Oxford Catalysts Group said:

"We are pleased to announce this second order for our FT product, following successful fulfilment of our first order from SGCE. Our partner has ambitious plans for commercial production of synthetic fuels, and we look forward to continuing to play a key role in their business.

"The market for small scale synthetic oil production is poised for rapid growth. We remain on track to take advantage of this significant opportunity."

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.
