Aging of solid acid catalysts (SAC) appears to be a hidden factor impacting the textural properties as well as the performance of catalysts. In this work, aged WO3-SO42--SnO2 catalysts were prepared via sol-gel method using two different percentage l

Solid acid catalysts of 15 wt.%SO4/SnO2 loaded with 5–45 wt.%WO3 were prepared, calcined at 400–800 °C, and then characterized by TG–DTA, XRD, FT-IR spectra and nitrogen adsorption techniques. The surface acidity was determined by potentiometr

New solid acid was prepared by loading of aged 15 wt.% SO 4 2 - /SnO2 catalyst with 15 and 35 wt.% WO3. The catalysts were calcined at 400 and 650 °C. The surface areas of the catalysts were determined by the data of N2 adsorption at −196 °C. The
