CRI Catalyst Company LP / hte begin research program

HOUSTON, Texas, AMSTERDAM, The Netherlands, and HEIDELBERG, Germany – [July 10, 2006] – CRI/Criterion, Inc., a Shell Group company, and an industry leader in refining and petrochemical catalyst products and technologies, and hte Aktiengesellschaft, the high-throughput experimentation company,
announced today that they are collaborating in the field of new catalyst discovery and development.

The new catalyst discovery and development work that is planned follows the success of the research program that CRI, Shell Global Solutions, and hte have undertaken together in the past year to validate hte’s proprietary technologies and methods for development of new generations of ethylbenzene dehydrogenation catalysts for the
production of styrene monomer.

hte has a custom-developed reactor technology that forms the basis of an application-focused, high productivity R&D capability for CRI and Shell Global Solutions. This system offers tight control of process parameters under challenging reaction conditions and high accuracy and precision of catalyst performance measurement.

”The application of hte’s proprietary reactor technology and experimental methods enables the rapid exploration of a multiplicity of catalyst formulation variables and process parameters simultaneously. The result is faster generation of new product and process leads. The hte tools complement our ongoing catalyst development work
at Shell’s Westhollow Technology Center in Houston. We look forward to continuing our work with hte staff to bring new ethylbenzene dehydrogenation catalyst products and technologies to market.”,says David Hamilton, CRI’s Manager of Heterogeneous Chemical Catalysis.

Hans Stapersma, Shell’s Enhanced Experimentation Platform Lead adds, “Shell continues to make optimal use of leading edge R&D technologies internally as well as externally for the benefit of our customers.”” “As the pace of innovation quickens it becomes ever more important for catalyst companies to find new ways to
deliver step-change new product into the marketplace with greater frequency,” notes Dirk Demuth, CEO of hte,“We greatly value the relationship that we have built with CRI/Shell whilst demonstrating the potential of our technologies to achieve this goal and look forward to further successes in using these tools in our upcoming
catalyst discovery program.”
