INTRODUCTION Structured packings of the corrugated sheet type have become increasingly popular for the application in distillation and absorption columns, due to their very good performance characteristics. Commonly, at suband near-atmospheric pressures, structured packings outperform random packings and trays in capacity and/or separation efficiency (see, e.g., Kurtz et al., 1991; Brunazzi, E....

Abstraet---A new development in the field of internals in packed columns is the use of structured packing types. Recently, a new structured packing type coated with a thin alumina layer (KATAPAK rM) has been developed, in this report, the results of an experimental and theoretical study concerning the possible applicability of this new packing material for hydrogenation processes in a trickle-b...

The industrial methane steam reforming reaction usually employs particulate catalyst that are easy to prepare and cost-effective, but suffer from problems such as high reactor pressure drop low overall utilization. In this study, the Ni-Al 2 CaO 4 powder prepared by equal volume impregnation method was subjected particle size control using a pressing method, made into particles of different siz...

in a graph g = (v,e), a subset s  v is said to be an open packing set if no two vertices of s have a common neighbour in g. the maximum cardinality of an open packing set is called the open packing number and is denoted by rho^o. this paper further studies on this parameter by obtaining some new bounds.
