Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]
, 2003 A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...
