Copper-zirconium-based Methanol Steam Reforming Catalyst

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a copper-zirconium (Cu51Zr14)-based catalyst, specifically tailored for methanol steam reforming to generate hydrogen. The catalyst starts as a bimetallic coating on a monolithic carrier and, upon exposure to methanol steam reforming conditions, transforms itself in situ into a highly active composite structure of finely-dispersed metallic copper and hydroxylated zirconium dioxide. This structure exhibits outstanding catalytic activity, stability, and very high selectivity for converting methanol to carbon dioxide and hydrogen with minimal production of undesirable carbon monoxide.
