Testing of HDS Catalyst in Trickle-Bed Reactor
Original language description
Green engine fuels need to fulfill severe limits of sulfur content. Therefore, permanent development of active and stabile HDS catalysts is necessary. Testing of catalysts life cycle needs long time experimentation in pilot scale reactors to evaluate catalyst decay and activity loses. To avoid occurrence of temperature gradients, poor catalyst wetting and fluid maldistribution a dilution of bed of industry scale catalyst particles by fine inert grains is used. In contradiction to full scale reactors this dilution changes interfacial area in the bed and affects namely external mass transfer of hydrogen. Also hydrodynamics, pressure drop, gas and liquid holdups and fluid axial dispersion seems to be quite different. The goal of this study was to evaluatehydrodynamic influence on experimental HDS catalyst activity measurement carried out in pilot scale trickle-bed reactor. Hydrodynamic data were evaluated by RTD method in laboratory glass model of pilot reactor. Mathematical models of th
