This allows CLG to better integrate crucial catalyst applications into its core technology offerings, promising more cohesive and innovative solutions for customers in the refining and renewables sector.
Chevron Lummus Global (CLG) has expanded its catalyst business through an agreement that reallocates a portion of the Advanced Refining Technologies (ART) portfolio, following W.R. Grace & Co.'s full acquisition of Chevron's stake in the ART joint venture.
The agreement, announced on November 3, 2025, is a direct result of Grace assuming full ownership of ART, a joint venture originally formed with Chevron U.S.A. Inc. in 2001. The ART hydroprocessing catalyst portfolio, a premier provider of catalysts for lower carbon intensity fuels, has now been divided between CLG and Grace. This strategic division allows both companies to concentrate on market segments that best align with their respective business strengths and objectives.
Chevron Lummus Global (CLG), a joint venture between Chevron U.S.A. Inc. and Lummus Technology, gains exclusive rights to develop, sell, and provide technical support for a specific suite of high-value catalyst applications. These key segments include hydrocracking, lubes hydroprocessing, and the EnHance™ isomerization portfolio for renewables hydroprocessing.
The expansion represents a "transformative step" for CLG, according to Rajesh Samarth, Chief Executive Officer of Chevron Lummus Global. "Expanding CLG's catalyst business will be a transformative step that will strengthen our ability to deliver more integrated technology and catalyst solutions," said Samarth. He emphasized the greater opportunities this provides to grow the catalyst portfolio, bring innovative products to market more effectively, and better meet evolving customer needs, especially in the context of increasing demand for renewable fuels.
Meanwhile, ART, under the sole ownership of Grace, will focus on its designated catalyst applications. These include fixed bed resid, ebullating bed resid, distillate hydrotreating, and the EnRich® portfolio for renewables hydroprocessing. Thomas Deman, President, Performance Catalyst Solutions at Grace, welcomed the new phase of collaboration, affirming Grace's continued commitment to the hydroprocessing catalyst industry. "We are proud to continue supporting CLG's hydrocracking, lubes, and EnHance™ catalyst offerings as well as their resid licensees," Deman stated, underscoring Grace's dedication to innovation and technical excellence.
The restructuring of the ART portfolio is designed to create a clear focus for both entities in the highly competitive hydroprocessing catalyst market. By gaining direct control over the catalysts that integrate most closely with its core licensing technologies—such as its expertise in hydrocracking and premium base oils—CLG can deliver a more streamlined, optimized, and integrated solution to its customers.
