The performance of a liquid-phase hydrogenation carried out in a monolithic reactor on an industrial scale has been studied by measuring temperature differences accurately. The process studied is the hydrogenator in the autoxidation process for large-scale production of hydrogen peroxide by Eka Chemicals, Akzo Nobel.Temperature differences are primarily caused by the exothermic reaction and can be...
Akzo Nobel, Eka Chemicals, produces hydrogen peroxide in a large scale using the anthraquinone (AQ) autooxidation process. The key step is the highly selective liquid-phase hydrogenation of the AQs to their corresponding hydroquinones. For this step, a unique hydrogenation technology employing a monolithic catalyst has been developed and implemented. The present contribution outlines the development...
