Comparative study of the catalysts Cr2O3-Al2O3, NaYCr and Cr2O3Si O2 in the interaction of NO with hydrocarbons

Written by sctunisie no comments

Chromium oxide, supported on alumina or silica aerogels, or incorporated into NaY zeolite, is tested as catalyst in the interaction of NO with hydrocarbons (C3 and C4). The results are compared and interpreted taking into account both the nature of the support and the E.S.R. data obtained with different samples in experimental conditions very close to those used for the catalytic tests.
