## Abstract

A method for producing methanol which comprises reacting a gas containing a carbon oxide and hydrogen in the presence of a catalyst comprising palladium supported on at least one oxide of metal selected from the group consisting of the metals of the Group IIa and Group IIIa of the short form of the Periodic Table.

## Claims

### Claim 1

A method for producing methanol which comprises reacting a gas containing a carbon oxide and hydrogen in the presence of a catalyst consisting essentially of palladium supported on at least one oxide of metal selected from the group consisting of yttrium oxide, lanthanum oxide and neodymium oxide.

### Claim 2 (depends on 1)

The method according to claim 1, wherein said reaction is conducted at a temperature of about 50.degree. to about 350.degree. C. at a space velocity of about 10.sup.2 to about 10.sup.5 hr.sup.-1 using a gas having a carbon oxide:hydrogen molar ratio of about 20:1 to about 1:20.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said reaction is conducted at a temperature of 150.degree. to 250.degree. C. using a gas having a carbon oxide:hydrogen molar ratio of 5:1 to 1:5.
