Abstract
The influence of concentration and method of phosphorus introduction in the alumina-supported nickel—molybdenum catalysts on the surface properties and catalytic activity in thiophene hydrodesulphurization (HDS) have been investigated. As a result of a strong interaction between phosphorus and support aluminium phosphates are formed. Molybdenum compounds, among them iso- and heteropoly compounds, are formed on the surface of Al 2O 3 irrespective of the presence of phosphorus. The promoting effect of phosphorus is expressed in optimization of the phase composition of the catalyst and a decrease in coke formation. A 1 wt.-% ensures the optimum composition of the polymolybdate surface structures and their homogeneous distribution.
