Hydrodesulfurization of petroleum distillates was studied kinetically to obtain the relationship between the process variables and the desulfurization degree. The oils used as the feed were straight heavy naphtha and gas oil obtained from an Arabian crude, the total sulfur content of which was 2.5%. With both of the naphtha and the gas oil, the ratio of total sulfur content of the feed to that of the product σ°/σf, could be expressed by the formulak=RT/gMLρ(1+m)[LHSV]ln(σ°/σf)which was in good agreement with the experimental results, where m is the hydrogen to oil mole ratio, ML is the average molecular weight of oil, ρ is the density of oil, T is the absolute temperature and k, g, R are constants. |
