Catalogue Number: ENE-101 Ene reductase enzyme for the reduction of C=C double bonds in presence of an electron withdrawing group (EWG) Examples of electron withdrawing groups are carbonyls (ketones and aldehydes) and nitro
In use, activated charcoal-based catalysts have a very much smaller rate of coke formation from anthracene than do alumina-based catalysts, and this difference is attributed to the relative acidity of the supports – the alumina being acidic while the carbon is said to be neutral , Martyn Twigg is the Chief Scientist of Johnson Matthey PLC .
Charcoal bases for catalysts are nearly always selected from the group known as “activated” charcoals The raw material from which “activated” charcoal is made is a carefully selected natural product which may be hard wood, nutshells, peat, or a blend of particular grades of coal and anthracite
Johnson Matthey catalysts are prepared on specially selected grades of activated charcoal that are often given further purification and activation treatments before being used as catalyst supports All the charcoals used have relatively high mechanical strength and stable particle size
