Title
Hydrogenation of carbon monoxide under mechanical activation conditions
Abstract

The work focuses on the hydrogenation of carbon monoxide over solid catalysts undergoing mechanical activation by ball milling. The rate of carbon monoxide conversion at individual ball impacts was estimated by measuring the impact frequency, the mass of powders involved in individual impacts and their duration. The rate of the mechanochemical hydrogenation process was compared with the one of the corresponding thermal process. An enhancement of the catalyst activity under mechanical activation conditions is observed.

Graphical abstractCarbon monoxide was hydrogenated over different catalysts under mechanical activation conditions and the mechanochemical reaction rate compared to the one observed under thermal activation conditions. The mechanical processing remarkably enhances the activity of the catalysts employed. The figure below shows the conversion data of carbon monoxide over a Ni-based catalyst.Figure optionsDownload full-size imageDownload as PowerPoint slide
