摘要: Activated carbon honeycomb (ACH) monoliths were prepared by extruding of a mixture bituminous coal and organic additives subsequent carbonization steam activation. Preparation parameters that varied temperature activation time. The conditions 500, 650 800 °C for 1 h the 850 2, 4 6 h. at various states characterized SEM, XRD, nitrogen adsorption compression test. It was found has significant effects on pore size distribution mechanical strength ACH monoliths. from high temperatures exhibited lower values BET surface area total volume higher value than those low temperatures. This attributed to effect results in formation relatively less defective structures.
