摘要：

A possibility of using aluminum hydroxide, a product of processing of the adsorbent that lost its sorption activity in purification of a polyethylene solution cyclohexane, was demonstrated in the synthesis of aluminum kaolin borate supports for hydrodesulfurization catalysis in oil refining. The influence of typical impurities V, Ti and Na in the composition of the spent adsorbent on the physicochemical and catalytic properties of supports and catalysts was determined. Alumina-kaolin-borate catalyst carriers with the Ti content of approx. 0.2% have been prepared by atomic layer deposition (ALD) of TiCl4 onto the granules. A positive effect of molecular layering with TiO2 has been revealed by temperature programmed reduction and oxidation in combination with hydrodesulphurization activity testing.
