LONDON, Ontario, April 23, 2026 (GLOBE NEWSWIRE) -- Aduro Clean Technologies Inc. (“Aduro” or the “Company”) (Nasdaq: ADUR) (CSE: ACT) (FSE: 9D5), a clean technology company using the power of chemistry to transform lower-value feedstocks such as waste plastics, heavy bitumen, and renewable oils, into resources for the 21st century, today announced that, through bench-scale testing, its Hydrochemolytic™ Technology (HCT) has been extended to highly paraffinic crude oils. To protect this advancement, the Company has filed a continuation-in-part (CIP) patent application with the United States Patent and Trademark Office (USPTO).
Key Highlights
The CIP extends the Company’s existing patent portfolio, which covers HCT’s prior applications in bitumen upgrading, and the chemical recycling of waste plastics. Initial experiments conducted with highly paraffinic crude oil samples, including both “yellow wax” and “black wax” feedstocks, originally sourced from Uinta Basin in Utah, have demonstrated the ability of HCT to reduce wax content and produce lighter crude that remains stable at ambient conditions at the bench scale, validating the technical application of HCT to highly paraffinic, waxy crude oils.
Paraffinic crude oils represent a significant and growing segment of global oil supply. A peer-reviewed study published in Energies estimates that approximately 16.4 to 27.1 million barrels of paraffin-rich crude oils are produced per day, representing roughly 20% to 33% of global crude production (Sousa et al., Energies, 2023, 16, 120). These feedstocks are increasingly recognized for favorable refining characteristics, including low sulfur and metals content, high cetane diesel yields, and premium performance in lubricant base oil and fluid catalytic cracker (FCC) applications.
Despite their inherent value, paraffinic crudes face structural constraints that limit how they reach and expand into different markets. High paraffin content strongly affects the cold flow properties, resulting in elevated pour points and wax formation at ambient temperatures, rendering the crude incompatible with conventional unheated pipelines. Moving paraffinic crude from wellhead to refineries typically requires unique logistics, including insulated railcars, heated storage tanks, and/or specialized offloading equipment with steam heating capabilities — all of which increase capital intensity, constrain market access, and depress realized value.
The Uinta Basin of northeastern Utah, USA illustrates these dynamics. One of the fastest-growing paraffinic crude production regions in North America, Utah produced approximately 185,000 barrels per day in 2025. The vast majority of which comes from the Uinta Basin (US Energy Information Administration). Similar transport and processing limitations affect major paraffinic streams globally, where paraffin-rich streams from producing regions across Africa, Asia, and the former Soviet Union face comparable dynamics. By improving flow properties and reducing reliance on heated logistics, technologies such as HCT have the potential to lower transportation costs, ease logistics challenges, and expand access to downstream markets, supporting improved value realization for paraffinic crude production.
Across these geographies, operators are increasingly seeking upgrading solutions that can break the dependency on specialized, high-cost handling infrastructure. Aduro's Hydrochemolytic™ Technology is designed to address these constraints by enabling targeted molecular transformation under moderate conditions to produce potentially transport-ready crude oils and intermediates that retain the favorable refining qualities of paraffinic feedstocks while reducing reliance on heated logistics and specialized receiving infrastructure.
“The Aduro approach to research is grounded in understanding how core reaction pathways can be applied across different hydrocarbon systems,” said Marcus Trygstad, Principal Scientist at Aduro. “Our work with paraffinic crude oils builds on what we have established in bitumen upgrading and the chemical recycling of waste plastics. Through bench-scale evaluation of multiple wax-rich samples, we have confirmed that Hydrochemolytic™ Technology can be applied to long-chain paraffinic structures, supporting new pathways for improving both handling and market access.”
“At Aduro, we continue to advance our Hydrochemolytic™ Technology platform through targeted applications that address real global challenges in the energy and materials sectors,” said Ofer Vicus, Chief Executive Officer of Aduro. “Paraffinic crude oils are widely produced and inherently valuable, but their full potential is often constrained by excessive handling and processing requirements. This extension reflects a practical step in expanding the relevance of our technology and its potential application across the hydrocarbon value chain. Each new application we validate strengthens HCT’s position as a platform technology, increases our value proposition, and broadens the set of potential markets and partners we can pursue over time.”
The extension into paraffinic crude oils reflects a continued expansion of HCT into adjacent hydrocarbon markets with significant business opportunities where molecular structure shapes both transport economics and access to refining value. While distinct from asphaltenic bitumen systems, paraffinic crudes present constraints that affect the capital intensity of production growth and the range of refineries able to process them. Aduro's work is focused on addressing these limitations through selective molecular conversion into more universally transportable and refinery-compatible forms. This may have significant economic impact by both reducing costs and increasing value by improving both the properties of paraffinic crude oils and their market access.
