DENITROGENATION BY ADSORPTION OF PYRIDINE ON NI/SUPPORT ADSORBENTS

In this work we have carried out the adsorption of pyridine using three different supports (activated carbon, SiO2 and y-Al2O3). After choosing the best support, due to its higher adsorption capacity, we have impregnated the support with nickel at three different concentrations (2, 4 and 6% w/w) by...
