In this properties is of great importance. In this\r\nstudy the gamma- study the gamma-alumina alumina alumina(γ-Al2O3) synthesized to be ) synthesized to beused as catalyst s used as catalyst s used as catalyst support for zeolite catalyst was o upport for zeolite catalyst was obtained by btained by\r\ncalcination of ammonium alum an intermediate product prepared from kaolin which was sourced from Kankara,\r\nKatsina, Nigeria. The surface properties were determined using BET technique. BET specific surface area ofgamma\r\nalumina produced at 825°C for soaking time of 3h was 120m2/g while at 850°C for soaking time of 4h the surface\r\narea was 140m2/g. The pore size and pore volume range from 15nm to 25nm and 0.5cm3/g to 0.8cm3/g\r\nrespectively. The XRD pattern obtained at respectively. The XRD pattern obtained at 825°C and 875°C calcination temperatures conformed 825°C and 875°C calcination temperatures conformedto the standard to the standard\r\npattern of gamma- pattern of gamma-alumina, having the strong peaks at Bragg angles o -alumina, having the strong peaks at Bragg angles of 67, 46, 39 and 38°. The SEM image showed 67, 46, 39 and 38°. The SEM image showed\r\nclearly the plate- clearly the plate-like structure of gamma alumina. like structure of gamma alumina. like structure of gamma alumina.Thus kankara kaolin is a pr Thus kankara kaolin is a pr Thus kankara kaolin is a promising material for the omising material for the production of production of\r\ngamma alumina."^^<http://www.w3.org/2001/XMLSchema#string> .
