Abstract:
1. A bulk catalyst comprising at least 60 wt % metal oxidic particles comprising one or more Group VIII metals and molybdenum, the bulk catalyst comprising less than 10 mole % of any Group VIB metal other than molybdenum (relative to the total amount of Group VIB metals) and a Group V metal in an amount less than 10 mole % (relative to the total of the Group VIB metals), which bulk catalyst has been calcined at a temperature below a temperature where the hexagonal metastable crystal structure changes to an inactive crystalline structure, and which bulk catalyst has a metastable hexagonal phase characterized by an X-ray diffraction pattern having reflections at 33-35 and 58-61° 2θ.
