The interesting catalytic properties of mayenite, related to its particular crystal structure, makes it suitable for use in catalyst synthesis. The objective of this study is to evaluate different preparation methods of a mayenite catalyst support. Three methods were studied (solid mixing in a high energy mill, solid mixing in a conventional ball mill and hydrothermal method) and samples were characterized by phase identification (XRD) and textural properties. The results showed that single phase mayenite (SBET 30.3 m /g) can be produced by high energy milling method. On the other hand, mayenite with a specific surface area of 57.0 m/g can be produced by the simple method of conventional ball milling. However, other phases were present in the sample. Mayenite produced was found to be promising for application as support on catalyst production.
