Abstract

Abstract

En 中文
• Urea boosts H2 yield from 8.10 to 10.70 mol/kg and carbon efficiency to 30.12%. • ·NH2 radicals from urea open aromatic rings of coal. • Nitrogen converts to liquid ammonia, enabling pollutant control and recovery. • Phenol is the key intermediate; its evolution correlates with gasification depth. • H2O serves as both reaction medium and primary H and O source for H2 and CO2.
