Why Existing Catalysts Weren't Built for This, And What Purpose-Built Looks Like

From Oil to Fuel — Part 2

Renewable oils aren’t just cleaner fossil fuels, they’re a genuinely different class of feedstock, often carrying far more oxygen and water than the sulfide-based catalysts refiners have relied on for decades were ever built to handle. In this Part 2 interview, NanosTech catalyst scientist Gerardo Vitale walks through why that mismatch causes conventional catalysts to deactivate, why the noble-metal alternative is chemically sound but commercially unworkable at scale, and how NanosTech’s carbide-based catalyst system closes that gap.

The piece also covers what it means for the market: a catalyst that can handle oxygen-rich, variable renewable feedstocks widens the pool of oils worth upgrading economically, and produces an output compatible with existing refinery infrastructure rather than requiring new plants.
