Molybdenum sulphide containing catalysts are provided which have been produced using a microemulsion approach. The catalysts thereby produced have a unique morphology which directly translates into improved performance in the conversion of syngas to alcohol and in the selectivity of this reaction towards producing ethanol.

Provided herein is a hydrotreating catalyst for hydrocarbon oil having high desulfurization activity, and high abrasion strength and high compressive strength. A process for producing the hydrotreating catalyst is also provided. The hydrotreating catalyst uses an alumina-phosphorus support. The support contains 0.5 to 2.0 mass % of phosphorus in terms of an oxide. The support loads a metal in Group 6A of the periodic table, and a metal in Group 8 of the periodic table. The hydrotreating catalyst has a specific surface area of 150 m.sup.2/g or more. The hydrotreating catalyst has a total pore volume of 0.40 to 0.75 ml/g as measured by a mercury intrusion method. The hydrotreating catalyst has two maximal peaks in a pore diameter range of 6 nm to 13 nm in a log differential pore volume distribution measured by a mercury intrusion method. The hydrotreating catalyst has an abrasion strength of 0.5% or less. The hydrotreating catalyst has a compressive strength of 15 N/mm or more. The support is produced from, for example, a hydrate obtained by adding phosphorus to an alumina hydrate obtained by using two mixtures of an acidic aqueous aluminum salt solution and a basic aqueous aluminum salt solution.

The invention discloses a binder-free high strength and low steam-to-oil ratio ethylbenzene dehydrogenation catalyst, which is characterized by comprising the following components in percentage by weight: (a) 60-85% Fe.sub.2O.sub.3; (b) 3-25% K.sub.2O; (c) 0.1-5% MoO.sub.3; (d) 3-20% CeO.sub.2; (e) 0.1-5% CaO; (f) 0.1-5% Na.sub.2O; (g) 0.1-5% MnO.sub.2, wherein the weight ratio of sodium oxide to manganese dioxide is 0.1-10; (h) 0.1-100 ppm of at least one element or oxide of Pb, Pt, Pd, Ag, Au, Sn; and no binder is added during the preparation of the catalyst. The low steam-to-oil ratio ethylbenzene dehydrogenation catalyst provided by the present invention contains no binder and maintains high strength, and has high activity and stability at low steam-to-oil ratio.

A process and catalyst is disclosed for converting a heavy hydrocarbon feed stream into lighter hydrocarbon products using a two component catalyst. The catalyst comprises iron and molybdenum containing catalyst. Alumina may be a third catalyst component. The molybdenum is present in the heavy hydrocarbon feed stream at about 500 wppm or less and the weight ratio of iron to the molybdenum is less than 5. Much lower concentrations of expensive molybdenum can be used due to the addition of iron in the catalyst.
