Abstract
Olefins of two to four carbon atoms are prepared by an improved Fischer-Tropsch process, the improvement comprising the use of a catalyst having a surface area less than about 100 m.sup.2 /g and consisting essentially of: (1) at least one material selected from the group consisting of the sulfide, oxide or metal of Mo, W, Re, Ru, Ni, Pd, Rh, Os, Ir and Pt; (2) at least one material selected from the group consisting of the hydroxide, oxicde or salt of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba and Th; and (3) optionally, a support.
Claims29
In a process for producing hydrocarbons by contacting carbon monoxide and hydrogen at reactive conditions, the improvement which comprises increasing the yield of olefinic hydrocarbons containing from two to four carbon atoms by contacting the carbon monoxide and hydrogen with a catalyst having a surface area less than about 100 m.sup.2 /g and consisting essentially of:
- (A) between about 1 percent and about 95 percent by weight based upon the weight of the catalyst of at least one material selected from the group consisting of the sulfide, oxide or metal of molybdenum, tungsten, rhenium, ruthenium, nickel, palladium, rhodium, osmium, iridium and platinum;
- and
- (B) between about 0.05 percent and about 50 percent by weight based upon the weight of the catalyst of at least one material selected from the group consisting of the hydroxide, oxide or salt of lithium, sodium, potassium, rubidium, cesium, magnesium, calcium, strontium, barium and thorium.
