HYDROCARBON MOLECULAR WEIGHT DISTRIBUTION AND MECHANISM OF THE FISCHER -TROPSCH SYNTHESIS ON COBALT CATALYSTS

We have carried out a quantitative analysis of the molecular weight distribution of hydrocarbons formed at different pressures. We have shown that a change in the distribution of hydrocarbons formed at elevated pressures occurs as a result of a change in the ratio between the rates of the individual reactions with preservation of the mechanism as a whole, while the difference between the distributions obtained at high and low pressures is explained by a change in mechanism for secondary reactions.
