Descripción
The influence of the preparation method on the properties of lanthanum-doped hematite prepared with potassium carbonate was studied aiming to get catalysts for styrene production from ethylbenzene dehydrogenation. The most active catalyst was obtained by adding the reactants on water. This solid has the highest intrinsic activity, the highest resistance against reduction and the lowest conversion drop. These properties were related to the presence of potassium compounds on the surface and to the presence of Fe+3 species (active phase) stabilized in lanthanum oxide lattice.
