Abstract
A process for hydrocracking and hydro-isomerization of a paraffinic feedstock obtained by Fischer-Tropsch hydrocarbon synthesis comprising at least 50 wt % of components boiling above 370° C. to obtain a hydro-isomerized feedstock, the process comprising contacting the feedstock, in the presence of hydrogen, at elevated temperature and pressure with a catalyst comprising a hydrogenating compound supported on a carrier comprising amorphous silica-alumina, the carrier having a pore volume of at least 0.8 ml/g, wherein at most 40% of the pore volume comes from pores having a pore diameter above 35 nm and wherein at most 20% of the pore volume comes from pores having a pore diameter below 50 Å and above 37 Å, the carrier having a median pore diameter of at least 85 Å, wherein the product of (surface area per pore volume) and (median pore diameter as measured by mercury intrusion porosimetry) of the carrier is at least 34,000 Å·m/ml.
