Abstract
The porosity and surface area of refractory oxides are modified by adding a lithium component thereto and then calcining. The resultant material, having a lower surface area, a lower total pore volume, and a larger average pore diameter in comparison to the original refractory oxide, is highly useful as a catalyst support, particularly with respect to hydrodesulfurization catalysts.
