Characterization of surface properties of nitrogen-enriched activated lignites by spectroscopic and chromatographic coupled with LSER modelling measurements

Fuel Processing Technology, 2002
One investigated way to prepare selective adsorbents towards mixtures of volatile organic compounds (VOCs) is to modify lignite by nitrogen-enrichment. These chemically modified coals are prepared by condensation of urea with the lignite before the carbonization/activation steps. This study describes a set of analytical tools able to explain in term of
