Cordierite catalyst support structure and its manufacturing method

摘要

This invention relates to a catalyst support structure, methods of preparing the support structure and a process for using the support structure. The catalyst support structure is composed of a substantially polycrystalline cordierite phase having a chemical composition by weight of 6-15 % MgO, 33-40 % Al2O3 and 45-56 % SiO2 and characterized in that it has a surface area of at least 2.7 m2/g and preferably 8 m2/g, a compressive strength of at least 31 MPa, a thermal expansion coefficient smaller than 5.2 x 10-6 m/m/°C and a porosity of at least 20 %.
