SBA-15, ZrSBA-15 and SZrSBA-15 were prepared with different Si/Zr ratio followed by sulfation using H2SO4. The samples were characterized by low angle XRD, wide angle XRD, Surface area measurement, TGA and Microcalorimetry measurements.  The acidity of SZrSBA-15 samples are higher than ZrSBA-15 samples and the acidity increases with Zr content indicating that Zr is responsible for holding the sulfate groups on the surface. These catalysts show good catalytic activity for cumene cracking and esterification but increment in esterification rate is lower than cumene cracking probably due to the fact that esterification needs stronger acidity.
