ABSTRACT:
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% Al.sub.2 O.sub.3 and 45-56% SiO.sub.2 and characterized in that it has a surface area of at least 2.7 m.sup.2 /g and preferably 8 m.sup.2 /g, a compressive strength of at least 31 MPa, a thermal expansion coefficient smaller than 5.2.times.10.sup.-6 m/m/.degree.C. and a porosity of at least 20%.
