WR Grace

United States

Grace Catalysts Technologies is recognized as the global leader in specialty inorganic catalysts. Grace develops and manufactures catalysts and related products and technologies used in energy and refining, polyolefins and plastics, as well as petrochemical, and other chemical manufacturing applications.

Chevron and Grace joined together in 2001 to form Advanced Refining Technologies (ART), with goals based on the values of our parents: technology expertise, world-class research and development, global manufacturing footprint, and a complete portfolio of hydroprocessing catalysts designed to meet the challenges of today's refiners. ART combines Grace's material science, manufacturing, marketing, and sales strength with Chevron's extensive experience operating its own refineries, catalyst development, and leadership in technology, design and process licensing.

For more than 50 years, Grace has been a leading producer of polyolefin cata­lysts and additive systems. Our heritage is in polyethylene catalysts, but through a series of acquisitions, partnerships and new investments, we have rapidly expanded in the polypropylene catalyst sector. In December 2013, Grace acquired UNIPOL® PP, a proprietary gas phase polypropylene process technology for the production of a broad range of polypropylene products. Our UNIPOL® PP licensing and catalyst business also includes UNIPOL UNIPPAC™ Advanced Process Control software.
