Analysis of the pore structure of activated carbons produced from paper mill sludge using small angle neutron scattering data

PDF Version Also Available for Download.

Description

A novel, cost-effective, and environmentally benign process was developed to produce highly efficient carbon-based adsorbents (CBAs) from paper mill sludge. The production process required chemical activation of sludge using zinc chloride and pyrolysis at 750 C in N{sub 2} gas. The produced CBAs were characterized according to their surface area and pore size distribution using N{sub 2}-BET adsorption isotherm data. Further characterization of the surface and pore structure was conducted using a unified exponential/power law approach applied to small angle neutron scattering (SANS) data. The structural features analyzed by SANS revealed the dependence of porosity with zinc chloride concentration. The ... continued below
