1 CREL ANNUAL MEETING November 15 th 2001 CHEMICAL REACTION ENGINEERING LABORATORY (CREL) CREL ANNUAL MEETING, 15 th November 2001 Eusebio Palmisano, Muthanna Al-Dahhan, P.A. Ramachandran DETERMINATION OF WETTING EFFICIENCY OF COMPLEX CATALYST’S SHAPES USING METHOD OF FUNDAMENTAL SOLUTIONS AND TRACER RESPONSE MEASUREMENTS.

2 CREL ANNUAL MEETING November 15 th 2001 WHAT WHAT..? Wetted Zone Dry Zone Wetting efficiency (f) Wetting efficiency (f) defined as the fraction of external catalyst surface wetted by flowing liquid WHY..? Trickle Bed Reactors are extensively used in the industry. The wetting efficiency is fundamental from scaling and design. The catalyst’s geometry should be optimized. HOW..? Pilot Plant Experiment using Stimulus Response Technique and... YOU CAN STOP BY AT MY POSTER AND I SHOW YOU TrilobeQuadrilobeHollow Cylinder AND… Catalyst in hydrotreating has complex geometries to reduce pressure drop
