Abstract

Hydrodesulphurisation in a fluidized bed offers the most attractive process for the desulphurisation of petroleum coke. Results of coke hydrodesulphurisation clearly indicate that the rate of sulphur removal is greatest at about 1100 K. The hydrodesulphurisation process is particularly effective with cokes of high sulphur content and high ash and heavy metals content, as at temperatures less than 1100 K the adverse effects of high ash and heavy metals content on desulphurisation is largely avoided. The process leads in general to increased porosity, density and surface area and improved reactivity. These properties are dependent on the sulphur concentration. The greater the amount of sulphur removed, the greater the structural changes expected in the coke treated. The weight loss is less than 10%.
