Witryna27 sty 1998 · The liquid phase hydrogenation of maleic anhydride was investigated in a packed bubble column reactor using different copper-based catalysts. A copper-zinc catalyst was found to be active in the formation of 1,4-butanediol, whereas on zinc-free copper catalysts, mainly succinic anhydride and γ-butyrolactone were formed. At …
Witryna25 lip 2002 · The interaction of H 2 with a Ru/MgO catalyst can be rationalized as follows: hydrogen preferentially dissociates on low-coordinated defectlike sites (“portal”-mediated adsorption). These species migrate to high-energy sites and subsequently fill up via diffusion the intermediate-energy and then the low-energy sites. hoys qualifer formWitryna29 sie 2011 · Prof. Dr. Wolfgang A.
