Synthetic mesostructured clays have been prepared using different silica sols to ascertain the importance of sol characteristics on the final matrix. For HDS, the conversion of dibenzothiophene (DBT) to biphenyl was examined at 400°C using Co/Mo/S-loaded mesostructured clay supports. The most active clay was derived from ludox silica sol AS-30, with an activity of 65% DBT conversion (86% for Crosfield 465). For deep HDS, the conversion of 4,6-dimethyldibenzothiophene was evaluated at 325°C and 350°C and compared to a Criterion 344 commercial catalyst. At 325°C, Cr344 exhibited 11.4% conversion. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
