Abstract

Abstract

En 中文
• Activator migration along the fixed-bed height created concentration gradients. • Rear-section enrichment of ZnCl2 increases the surface area by 30% and forms micro-mesoporous AC. • Migration of K2C2O4 to the rear promotes gasification, yielding AC with > 95% microporosity. • Rear accumulation increased AC yield with ZnCl2 but decreased with K2C2O4. • In-situ IR confirms stabilization of carbon framework with ZnCl2 and deoxygenation with K2C2O4.
