Synthesis of light olefins from CO and H2over highly dispersed Ru/K–Al2O3derived from Ru3(CO)12

Abstract

A highly dispersed Ru/Al₂O₃ catalyst, prepared from Ru₃(CO)₁₂ was much more active and selective for C₂–C₅ olefins in the hydrogenation of CO than conventionally prepared Ru/Al₂O₃ catalyst, and addition of K to the carbonyl-derived catalyst enhanced significantly the preferential formation of light olefins (ca. 80% at 260 °C).
