Hot Article: TAPping into adsorption to improve catalysis

All TAP micro-reactors have inert particles which are used so that the catalyst zone can be maintained under isothermal conditions. Even on “inert” particles adsorption will occur to some degree; however, the extent to which this occurs has a critical influence on the analysis of the TAP data.

In their recent paper, Chris Hardacre and co-workers, from Queen’s University, Belfast, UK, discuss the development of a function which accounts for the adsorption over the inert material, so that the TAP data analysis can be accurately determined. They also demonstrate this analysis method using the selective reduction of oxygen in a hydrogen rich ethylene feed over silver catalysts as a case study. Find out how they got on by reading their Catalysis Science & Technology Hot Article.
