hte GmbH pioneered the development of state of the art catalyst testing workflows in parallel fixed bed reactors at different scales (1�100 ml) and numbers of parallel reactors (1-48) to measure catalyst activity and selectivity (kinetics, screening, quality control) for the refining and petrochemical industries.Residue hydrotreating on stacked beds of extrudate catalysts  with different functionalities for demetallation (HDM), desulfurisation (HDS), denitrofication (HDN) and different bed length were tested at constant conditions in a 16xfold parallel reactor test rig. The study showed that the HDS activity follows the experimental catalyst design and the effect of the independent variables can be used to build a kinetic model based on a single experiment.Hydrocracking of a hydrotreated VGO  was studied for 4 extrudate benchmark catalysts in a 16xfold parallel fixed bed reactor test rig. Interpolation of the 350+Conversion vs. reactor temperature led to a clear differentiation of the catalysts with a precision better than 1�C. The precision of the middle distillate selectivity at constant conversion was better than 0.5 % absolute.Reforming of C5-C14 Naphtha  is the only hydrogen formation process in a classic refinery and the objective is to convert Naphthenes and other hydrocarbons to Aromatics, maximizing hydrogen, C5+ while minimizing C1-C4 cracking product yields. Since reforming is a very endothermic reaction the commercial CCR and fixed bed reactors require intermediate reheating, i.e. specific, pronounced temperature profiles need to be simulated on the laboratory scale. hte developed packing procedures for powder and full extrudates in fixed bed reactors that can be tuned to simulate such temperature profiles and allow realistic testing of reforming catalysts in parallel fixed bed reactors.
