Heterogeneous catalysts

A process for converting a feedstream comprising syngas and ethylene to a product stream that comprises at least one three carbon oxygenate, which process comprises placing the feedstream in contact with a heterogeneous catalyst under conditions sufficient to effect conversion of the feedstream to the product stream, the catalyst comprising a combination of metals on a catalyst support, the combination of metals being represented by general formula RhaAgbSncXdYeOx wherein X is at least one transition element other than rhodium or silver, Y is at least one element selected from alkali metals and alkaline earth metals, a is a real number within a range of from 0.1 millimole/hectogram to 50 millimole/hectogram, b is a real number within a range of from 0.1 millimole/hectogram to 50 millimole/hectogram, c is a real number within a range of from 0.1 millimole/hectogram to 50 millimole/hectogram, d is a real number within a range of from 0 millimole/hectogram to 250 millimole/hectogram, e is a real number within a range of from 0 millimole/hectogram to 1500 millimole/hectogram, and x is a real number greater than zero needed to balance the total charges of Rh, Ag, Sn, X and Y elements, the catalyst support being at least one of silica, alumina, titania, magnesia, magnesium aluminate, and zinc aluminate.
