The origin of the particle-size-dependent selectivity in 1-butene isomerization and hydrogenation on Pd/Al2O3 catalysts

The selectivity of 1-butene hydrogenation/isomerization on Pd catalysts is known to be particle size dependent. Here we show that combining well-defined model catalysts, atmospheric pressure reaction kinetics, DFT calculations and microkinetic modeling enables to rationalize the particle size effect based on the abundance and the specific properties of the contributing surface facets.

Intrinsic kinetic study of 1-butene isomerization over magnesium oxide catalyst via a Berty stationary catalyst basket reactor

The intrinsic kinetics of 1-butene isomerization over a commercial MgO catalyst was studied by using a Berty-type reactor (gradient-less recycle reactor) without limitations of heat-, external mass-, and internal mass-transfers.

Silicalite-1 zeolite acidification by zinc modification and its catalytic properties for isobutane conversion

Silicalite-1 zeolite was successfully acidified by zinc modification, the prepared Znx/S-1 catalysts exhibited excellent catalytic performances in both isobutane dehydrogenation and butene isomerization reactions.
