Although gamma-alumina is one of the most used alumina transition phases, its characterization is still done with the help of kernels of approximate isotherms, based on spherical or cylindrical silicate pores, originally applied in the characterizations of zeolites.
Considering the hierarchical nature of gamma-alumina, with pores in the range of micropores and mesopores, it is important that the range of micropores has a more accurate characterization. To cope with the problem of approximated kernel, we developed a new dedicated kernel (Micro_gamma), using adsorption isotherms from N2 to 77 K, suitable for analysis of the micropore range of gamma-alumina samples.
Experimental N2 isotherms at 77 K of your gamma-alumina sample can be submitted here and we will return (by e-mail), with a file containing the PSD and other relevant information from the microporous region.
