Cobalt-containing smectite-like mesoporous material as a new type of catalyst for hydrodesulfurization of thiophene
Cobalt-containing mesoporous smectite-like material (SM(Co)) was prepared by a hydrothermal method and used as a catalyst for hydrodesulfurization (HDS) of thiophene. It is active by itself and produces mainly butenes and a small amount of n-butane. When platinum is added to this material, the HDS activity is enhanced by 50%, while the product distribution does not change so much. The platinum-loaded sample should have two types of active sites, one originally present in the smectite-like material and the other with platinum, the latter being different in nature from a sample of platinum supported on silica gel. Thus, the SM(Co) and Pt/SM(Co) samples are new types of HDS catalysts.
