A catalyst composition comprises (a) alumina, (b) zinc titanate, (c) at least one compound of molybdenum, (d) at least one compound of at least one of nickel and cobalt, and (e) at least one compound of rhenium. This catalyst composition is used for hydrotreating a liquid hydrocarbon-containing feed stream, which contains organic compounds of sulfur, nitrogen and oxygen under such conditions as to obtain a product having reduced levels of sulfur, nitrogen and oxygen. Preferably the hydrocarbon-containing feed stream contains cycloalkanes, which are at least partially reformed to aromatic compounds.
