The monolayer adsorption quantities of different adsorbates on Ni-W/F-Al2O3SiO2 were determined using both TPD and adsorption methods. The internal and external surface structure and the geometrial distribution of the acid sites of the catalyst were analyzed using the concept of fractal geometry. A physical adsorption dimension of 2.485 and a chemical adsorption dimension of 2. 901 were estimated based on the experimental data.
