PROCESS FOR REMOVING IMPURITIES IN FEEDSTOCKS

The invention relates to a process and plant for removing one or more impurities from a feedstock, said process comprising the step of contacting said feedstock with a guard bed comprising a porous material, thereby providing a purified feedstock; wherein the porous material comprises at least 80 wt% of magnesium aluminate spinel (MgAl₂O₄), titania (TiO₂), or a mixture thereof; and the porous material has a total pore volume of 0.50-0.90 ml/g, as measured by mercury intrusion porosimetry. The invention envisages also a process and plant in which the guard bed comprises a porous material which is at least 80 wt% SiO₂.
