Performance Testing of Hydrodesulfurization Catalysts Using a Single-Pellet-String Reactor

Small-scale parallel trickle-bed reactors were used to evaluate the performance of a commercial hydrodesulfurization catalyst under industrially relevant conditions. Catalyst extrudates were loaded as a single string in reactor tubes. It is demonstrated that product sulfur levels and densities obtained with the single-pellet-string reactor...

Catalysis engineering on three levels

The relevance of levels in space and time for chemical engineering are discussed. Catalysis Engineering is introduced as an emerging new discipline. In Catalysis Engineering three levels can be distinguished: the microlevel focusing on molecules and catalytic sites, the mesolevel focusing on the catalyst particle and the catalytic reactor, and...
