Hydrotreating catalyst and process.

摘要

Hydrotreating catalysts comprise a hydrogenating component and a support comprising at least one porous refractory inorganic oxide, said catalyst having BET surface area of 150 to about 190 m<2> g. nitrogen desorption pore volume of 0.8 to about 1.2 cc/g in micropores with radii up to 600 ANGSTROM , with at least 0.7 cc/g of such micropore volume in pores having radii ranging from 50 to 600 ANGSTROM , mercury penetration pore volume of 0.1 to about 0.5 cc/g in macropores with radii of 600 to 25,000 ANGSTROM and bulk density of about 0.3 to about 0.5 g/cc. Hydrotreating process comprises contacting a hydrocarbon feed susceptible to upgrading with hydrogen in the presence of the aforesaid catalysts under hydrotreating conditions. The catalyst and process are particularly useful in hydrotreating feeds comprising high metals or high metals and sulfur content materials.
