Abstract
Hydrocarbons of two to four carbon atoms are prepared by an improved Fischer-Tropsch process, the improvement comprising the use of a catalyst comprising: (A) at least one material selected from the group consisting of the sulfide, oxide or metal of Mo, W, Re, Ru, Ni and Pt; (B) at least one material selected from the group consisting of the hydroxide, oxide or salt of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba and Th; and (C) a support. The catalyst demonstrates good C.sub.2 -C.sub.4 selectivity, is resistant to sulfur poisoning and is regenerable.

In a process for producing hydrocarbons by contacting carbon monoxide and hydrogen at reactive conditions, the improvement which comprises increasing the yield of the saturated and unsaturated hydrocarbons containing from two to four carbon atoms by contacting the carbon monoxide and hydrogen with a catalyst consisting 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 metal, oxide or sulfide of molybdenum, tungsten, rhenium, ruthenium and platinum;
- (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;
- and
- (C) at least about 1 percent by weight based upon the weight of the catalyst of a support.
In a process for producing hydrocarbons by contacting carbon monoxide and hydrogen at reactive conditions, the improvement which comprises increasing the yield of the saturated and unsaturated hydrocarbons containing from 2 to 4 carbon atoms by contacting the carbon monoxide and hydrogen with a catalyst consisting 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 metal, oxide or sulfide of molybdenum and tungsten;
- (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;
- and
- (C) at least about 1 percent by weight based upon the weight of the catalyst of a support.
In a process for producing hydrocarbons by contacting carbon monoxide and hydrogen at reactive conditions, the improvement which comprises increasing the yield of the saturated and unsaturated hydrocarbons containing from 2 to 4 carbon atoms by contacting the carbon monoxide and hydrogen with a catalyst consisting of:
- (A) at least about 10 percent by weight based upon the weight of the catalyst of at least one material selected from the group consisting of the metal, oxide or sulfide of molybdenum and tungsten;
- (B) at least about 0.5 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;
- and
- (C) at least about 80 percent by weight based upon the weight of the catalyst of a support.
