Abstract
Linear alpha olefins having from four to twenty carbon atoms and low amounts of oxygenates are synthesized, by producing a synthesis gas containing H2 and CO from natural gas and passing it over a non-shifting cobalt catalyst at reaction conditions of temperature, % CO conversion, and gas feed H2:CO mole ratio land water vapor pressure, effective for the mathematical expression 200−0.6T+0.03PH2O−0.6XCO−8(H2:CO) to have a numerical value greater than or equal to 50. This process can be integrated into a conventional Fischer-Tropsch hydrocarbon synthesis process producing fuels and lubricant oils.
