Abstract
Excellent
desulfurization is achieved via reactive adsorption using Friedel-Crafts
acylation materials. For model oil, thiophenic compounds including
dibenzothiophene, benzothiophene, and thiophene, are removed completely by
AC–AlCl3 within 30 min at room temperature.
Thiophenic compounds are acylated by AC under the catalysis of
AlCl3, and the acylated derivatives are stronger base than the originals thanks
to incorporation of O-containing carbonyl group (CO) and, consequently,
adsorbed more easily by AlCl3 via Lewis acid–base complexation.
