Claims
- 1. In a process for producing an oxygen-containing hydrocarbon compound having 1 or 2 carbon atoms which comprises reacting a gaseous mixture of a carbon oxide and hydrogen in the presence of a hydrogenation catalyst, the improvement wherein said hydrogenation catalyst is a catalyst composition consisting essentially of
- (i) substantially metallic rhodium;
- (ii) a metal element selected from the group consisting of niobium, tantalum and rhenium;
- (iii) an oxide of a metal selected from the group consisting of zirconium and titanium; and
- (iv) silica.
- 2. The process of claim 1 wherein said metallic rhodium is formed from a simple salt of rhodium.
- 3. The process of claim 1 wherein the amount of said metallic rhodium is about 0.0001 to about 50% by weight based on the weight of said catalyst composition.
- 4. The process of claim 1 wherein the weight ratio of metallic rhodium to said metal element is from 10:1 to 1:10.
- 5. The process of claim 1 wherein the weight ratio of the metal oxide to silica is from 100:1 to 1:100.
- 6. The process of claim 1 wherein the amount of silica is about 0.001 to about 99.9% by weight based on the weight of said catalyst composition.
- 7. The process of claim 1 wherein said reaction is carried out at a temperature of about 50.degree. to about 450.degree. C. and a pressure of about 0.5 to about 350 atmospheres (gauge) at a space velocity of about 10 to about 10.sup.6 liters/liter.hr.sup.-1.
- 8. The process of claim 1 wherein the carbon oxide is carbon monoxide.
- 9. The process of claim 1 wherein the mole ratio of the carbon oxide to hydrogen is from 20:1 to 1:20.
- 10. The process of claim 1 wherein said catalyst composition consists of the components (i), (ii), (iii) and (iv).
