Abstract

In this paper, a theoretical optimization of shaped catalyst dimensions with technologically imposed constraints is presented for operating conditions of a typical methanol reformer. A comprehensive two-dimensional mathematical model of a single reformer tube containing physically sound correlations for heat transfer parameters of holed catalyst particles is used. Three-hole pellets and Raschig rings were used as examples. A general conclusion is made that holed steam reforming catalysts should have maximum catalyst height and minimum diameter determined by requirements of uniform catalyst packing.
