Rive Technology and Grace Enter Joint Development and Commercialization Agreement  

Rive Technology Inc., an innovative catalyst technology company for the petroleum refining industry, announced today that it has entered into an agreement with W.R. Grace & Co.-Conn., the primary U.S. operating company of W.R. Grace & Co. (NYSE: GRA). Rive and Grace will jointly develop and commercialize Rive’s zeolite technology for use in catalysts for fluid catalytic cracking (FCC) processes within a petroleum refinery.

Rive’s proprietary technology makes zeolite refining catalysts more accessible to hydrocarbon molecules, resulting in increased yields of transportation fuels and less coke. Rive’s technology creates refinery-wide operating flexibility due to enhanced coke selectivity. Refiners can profit from the improved catalytic performance by increasing refinery throughput, processing heavier crude oil, and maximizing production of high quality fuels.

Under the agreement, Rive and Grace will develop, manufacture and market FCC catalysts incorporating Rive’s technology worldwide. “Grace’s world-class catalyst formulation expertise and manufacturing capabilities will be critical to our success, “said Larry Evans, Chief Executive Officer of Rive Technology. “Together, we can extend Grace’s technical and market leadership.”

”This agreement represents a unique opportunity to leverage Rive’s capabilities with our development and scale-up expertise in order to commercialize step-out FCC products that meet our customers’ needs,” said Shawn Abrams, Vice President and General Manager, Grace Davison Refining Technologies. “Rive brings a strong team of scientists to this effort and we look forward to jointly pursuing this innovation in FCC catalysis.”
