Carbon Honeycomb Structures For Adsorption Applications

Activated carbon honeycomb structures based on synthetic precursors are described. These strong, highly durable honeycombs are continuous interpenetrating structures of activated carbon and a ceramic with adjustable broad range of carbon percentage (5-95 wt%). Dynamic adsorption performance of a particular honeycomb structure containing 18wt% carbon is described with respect to various adsorbates, i.e. butane, toluene, formaldehyde, isopropanol etd., and the importance of space velocity in determining the adsorption performance as well as the effect of structural parameters on the performance is shown.
