Abstract
Abstract This invention relates to a composition, a method of preparing the composition and a catalyst using the composition. The composition consists essentially of a layered clay homogeneously dispersed in an inorganic oxide matrix. The clay is dispersed in such a way that the clay layers are completely surrounded by the inorganic oxide matrix. The inorganic oxide is selected from the group consisting of alumina, titania, silica, zirconia, P 2 O 5 and mixtures thereof. The clay can be a natural clay such as montmorillonite, a metal exchanged clay (Fe +3 exchanged) or a pillared clay such as aluminum chlorohydrate (ACH) pillared clay. The composition can be used as a catalyst for alkylation or hydrocracking or metals can be dispersed on it to provide a catalyst which is also useful for hydrocracking or alkylation.
