Property of alumina to adsorb long chain normal-paraffin hydrocarbons
That alumina can strongly absorb long chain normal-paraffin hydrocarbon was found when alumina was used in the preparative group-type separation of heavy petroleum fractions. The reason for the above property ...

NO adsorption study on the distribution of Ni2 + ions on the various micro-environments of carriers
The decrease of the electron density in the d orbits of Ni2 + ions, resulting from the disturbance of micro-environments in which Ni2+ ions are located, makes the frequency of adsorbed NO shlft higher. The shift ...
