摘要：
NCONVENTIONAL sulphated zirconia (SZ) catalysts were prepared and examined for n-pentane isomerisation in this investigation. The sulfation was performed using H2SO4 acid. The calcination step seems to attain the highest influence using our sol-gel preparations, where the crystallinity transforms to the denser form. However, the surface properties do not exhibit such effectiveness. Calcination at 500 degrees C gives the best activities and stabilities, whereas at 650 degrees C, calcination is deteriorative. IR spectra, TPR, TGA, DSC, XRD and surface properties of the current catalysts were investigated.
