OXFORD CATALYSTS GROUP PLC

("Oxford Catalysts" or "the Group")

GTL Engineering Study

Oxford Catalysts Group PLC, the leading technology innovator for synthetic oil production, is pleased to announce that it has been selected to participate in a Gas-to-Liquids ("GTL") engineering study on behalf of a $multi-billion Exploration & Production company. The study (known as an FEL1) will evaluate a 5,000-15,000 bpd GTL facility in a North American location designed to convert shale gas into finished synthetic fuels. The study is being conducted by a major engineering firm and will last several months with a projected seven figure ($) budget. The results will be used to select the project's technology providers.

Roy Lipski, CEO of Oxford Catalysts Group said:

"We are pleased to have been given an opportunity to participate in this study, and potentially in this major project as a technology provider. This prospect underscores the increasing awareness of our technology within the industry and the growing market interest in smaller scale synthetic fuels production."

Notes to Editors

Oxford Catalysts designs and develops technology for the production of synthetic oil from both conventional 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.
