A simple engineering approach is presented to describe the heat transport performance of a tubular set-up loaded with closed cross-flow structure (CCFS) packing elements, based on the dominant convective contribution of liquid to heat transport. This

Several structured packing elements for multiphase tubular fixed bed reactors are compared with regard to catalyst hold-up, heat transfer performance and pressure drop. Structured packings with catalyst coating typically exhibit low pressure drop com

Improvements in catalyst activity make the heat transport in fixed bed reactors increasingly important. Structured packings operated in two-phase flow are expected to outperform randomly packed beds, but heat transfer data on structured packings is s

Atomic layer deposition (ALD) is a promising technique for coating micrometer- and nanometer-sized particles. Due to the self-terminating nature of the ALD half-reactions, the coating thickness can be controlled to the atomic level by choosing the nu

Cross-flow structured packings for tubular fixed bed reactors operated with co-current gas–liquid flow perform significantly better in terms of overall heat transfer than a randomly packed bed (glass beads), knitted wire packing, and Al-foam struct

The potential of four structured packings has been explored for application in highly exothermic multiphase reactions such as the Fischer–Tropsch synthesis where removal of reaction heat is a major issue in the packed bed reactor type. Efficient he
