Abstract
A new method for the synthesis of hydrocarbons with chain lengths of from 2 to 10 carbon atoms inclusive and for selective generation of olefinic hydrocarbons in this carbon number range with reduced wax formation, said products being synthesized from CO and H.sub.2 at pressures of from 100 to 3100 kPa which method comprises the steps of passing a synthesis gas stream of CO and H.sub.2 at a H.sub.2 /CO ratio of from 0.1-10 at a space velocity of from 100 hr.sup.-.sup.1 to 50,000 hr.sup.-.sup.1 over a catalyst comprising from 0.01 to 15 wt. % ruthenium on TiO.sub.2, other titanium-containing oxides or mixtures of said titanium-containing oxides for a time sufficient to effect the generation of desired olefinic hydrocarbon products, at a temperature of from 100.degree. to 500.degree. C and a pressure of from 100 to 10.sup.5 kPa (1-1000 atm). The supported ruthenium catalyst has a BET surface area of from 10 to 60 m.sup.2 g.sup.-1 of total catalyst with a ruthenium crystallite size of preferably less than 5 nm (50 A).
