摘要： This invention relates to a hydrocarbon synthesis process. More particularly, but not exclusively, this invention relates to a Fischer Tropsch Process employing an activated catalyst and to the use of such an activated catalyst, wherein the Fischer Tropsch Process conditions favor the attainment of a low acid selectivity.
