摘要： The invention relates to a porous material comprising alumina, said alumina comprising alpha-alumina, said porous material comprising one or more metals selected from Co, Mo, Ni, W and combinations thereof, and said 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, such as pores with a radius up to 5000 Å. The invention relates also to a process for removing impurities such as phosphorous (P) from a feedstock such as a renewable feed, by contacting said feedstock with a guard bed comprising the above porous material. The invention further relates to a guard bed for a hydrotreatment system comprising the porous material, a hydrotreatment system comprising a guard bed which comprises the porous material and a downstream hydrotreatment section comprising at least one hydrotreatment catalyst, as well as to the use of the porous material as a phosphorus guard in a hydrotreatment process.

摘要： A method for activating an oxidic fresh hydroprocessing catalyst or the catalytically active material of a spent hydroprocessing catalyst comprising a refractory oxide support and one or more base metals selected from Ni, Co, Mo and W comprises optionally regenerating the catalyst, adjusting an aqueous activating solution, which contains an organic acid, to pH > 3 with an alkaline additive, impregnating the catalytically active material with the pH-adjusted aqueous activating solution, and heat-treating the catalyst at a temperature of 120-450°C.
