Abstract
An improved method is disclosed for the selective synthesis of low molecular weight olefins, particularly C.sub.2 and C.sub.3 olefins inclusive, which method comprises the steps of passing a CO and H.sub.2 synthesis gas stream over a catalyst at a temperature and pressure and for a time sufficient to generate the desired olefinic products, wherein the improvement consists in using as a catalyst ruthenium on a support selected from the group consisting of a manganese oxide, other manganese-containing oxides or mixtures of various manganese oxides. The weight loading of the ruthenium may range from about 0.01 to about 15 wt. % based on the total catalyst weight. The operating conditions of the instant process are the standard Fischer-Tropsch synthesis reaction parameters, preferably an H.sub.2 /CO mole ratio of from about 10 to about 0.1, a space velocity of from about 100 hr.sup.-1 to about 50,000 hr.sup.-1, a temperature of from about 100.degree. C. to about 500.degree. C. and a pressure of from about 103 to about 1.03.times.10.sup.5 kPa (103 kPa - 1 atm). The instant process is also marked by a reduced methane make.
