Abstract

PURPOSE: To obtain a catalyst precursor having poisoning resistance and preventing coking, as the hydrogenation catalyst precursor of a heavy oil, by supporting copper oxide on a titania carrier to which heat stability is imparted by tungsten oxide.
CONSTITUTION: To anatase type titania which is the carrier of a hydrogenation catalyst for a polycyclic aromatics and ash containing heavy oil, heat stability is imparted by tungsten oxide prior to supporting an activator thereto to prevent transformation thereof to rutile type titania and copper compound is supported to the heat stabilized titania as the activator. This catalyst is highly resistant to a poisoning substance such as ash or halogen in hydrogenation reaction of the heavy oil and can avoid coking.
