摘要： A porous material including alumina, the alumina including alpha-alumina, the porous material including one or more metals selected from Co, Mo, Ni, W and combinations thereof, and the porous material having a BET-surface area of 1-110 m2/g, a total pore volume of 0.50-0.80 ml/g, as measured by mercury intrusion porosimetry, and a pore size distribution (PSD) with at least 30 vol % of the total pore volume being in pores with a radius ≥400 Å, suitably pores with a radius ≥500 Å. A process for removing impurities such as phosphorous (P) from a feedstock, by contacting the feedstock with a guard bed including the above porous material. A guard bed for a hydrotreatment system including the porous material, a hydrotreatment system including a guard bed which includes the porous material and a downstream hydrotreatment section including at least one hydrotreatment catalyst.
