("Oxford Catalysts" or "the Group" or "the Company")

Mourik Agreement for Commercial Catalyst Handling

Oxford Catalysts Group (OCG.L), the modular Gas-to-Liquids technology innovator, is pleased to announce that it has signed a service agreement with Mourik LP to provide catalyst handling services for the Group's commercial Fischer-Tropsch (FT) reactors.

The replacement of spent with fresh catalyst every two to five years is required for all FT technologies. Mourik has been working closely with the Group for over a year to qualify procedures for loading and unloading catalyst from the Group's commercial FT reactors to be deployed in modular plants.

Catalyst replacement (loading and unloading), activation, and regeneration of the Group's FT units is quicker and / or easier than with competing FT technologies, thereby simplifying logistics and enabling improved asset utilisation.

Headquartered in the Netherlands, the Mourik group is a global leader in catalyst handling with a turnover of €415 million (2011) and offices in Europe, North and South America, Asia and the Middle East. The service agreement with Mourik ensures that the Group's customers receive preferred service and best available pricing for their catalyst handling requirements.

Roy Lipski, CEO of Oxford Catalysts Group, said:

"We are delighted to be able to provide catalyst life-cycle services to our customers through Mourik, a world leader in this field. This preferred relationship with Mourik is another element in place ensuring our readiness for commercial roll out and the expected growth in sales."

Albert Megens, Business Unit Manager of Mourik LP, said:

"Innovation is what drives Mourik, and we are pleased to be working with Oxford Catalysts to service their novel reactors wherever they may be in the world. Small scale GTL is a very exciting emerging market and we're glad to be positioned with the Group to benefit from its future growth."

Notes to Editors

Oxford Catalysts enables modular Gas-to-Liquids ("GTL") plants to convert unconventional, remote and problem gas into valuable liquid fuels. Systems based on the Group's technology (marketed under the brand name Velocys) are significantly smaller than those using conventional technology, enabling modular plants that can be deployed cost effectively in remote locations and on smaller fields than is possible with competing systems. Together with world-class partners, Oxford Catalysts provides complete modular GTL solutions that address an untapped market of up to 25 million barrels of fuel a day.

Oxford Catalysts Group PLC is listed on the AIM market of the London Stock Exchange (LSE: OCG). The Group has some 85 employees with facilities near Oxford, UK and Columbus, Ohio, USA.
