    摘要: Extruded isomerization catalysts comprising MgO, a metal silicate clay binder and a stabilizer and methods of forming such isomerization catalysts are disclosed. Also disclosed are isomerization catalysts that exhibit a fresh isomerization rate and an aged isomerization rate that is at least 50% of the fresh isomerization rate. Embodiments of the isomerization catalysts disclosed herein include metal silicate clay binders that include a layered structure and metal silicate. The metal silicate clay binder may be present in an amount in the range from about 5 wt % to about 20 wt %. Exemplary stabilizers include one or more of ZrO2, tetravalent rare earth metal and a trivalent rare earth metal. Stabilizers may be present in an amount up to about 40 wt %. One or more improved properties, such as piece crush strength and isomerization performance, are exhibited by the catalyst article.

    摘要: Methods are disclosed for providing a library of composite or novel composition samples on a support. The method involves depositing one or more components as concentration gradients on the surface of the support. The concentration gradients are placed on the support in the form of superimposed triangles which allow ready formation of composite or composition samples containing three or more components. The samples can be removed from the support by drilling out portions of the coated support so as to yield individual tablets containing the support with one or more component layers thereon. By using this method, a vast number of samples can be made.
