MTE supplies a complete range of catalyst grading media. The Rest-O-Top® range of products consist of inert ceramic top layers, porous alumina gradings and active gradings in different shapes and designs. The selection of grading media for different applications and units is very depending on the feed stock, catalyst and experiences with this unit.

MTE has a standard range of solutions, but also supplies tailor made gradings. We are able to assist you to select the best combination of products suitable for your application to reduce pressure drop built-up, capture all sizes of particles and catalyst poisons and protect the catalyst from scaling leading to a longer unit runs.
