Abstract

The structure of mixed layers resulting from thermal treatments or Kr ion bombardment and post-thermal annealings of thin film Fe/Pd bilayers has been investigated using X-ray diffraction and transmission electron microscopy. Ion mixing experiments were performed using 200 keV Kr²⁺ ions at a dose of 2.5 × 10¹⁶ cm⁻². Thermal treatments were carried on in flux of formings gas at 350 and 550°C. In the ion-mixed samples the dominant phase is FePd₃ and the part of the iron film which is not mixed with palladium is heavily structurally modified. Annealings induce compositional changes both in as-deposited and ion-mixed samples: at the highest temperature we detected the formation of the FePd compound in the as-deposited sample, while the composition of the ion-mixed sample moves towards the same phase but without reaching it yet.

A membrane reactor for the production of sytrene from ethylbenzene
1993, Journal of Membrane Science
A rigorous dusty gas model for the catalyst pellet was used in a heterogeneous model of the industrial fixed bed catalytic reactor for the dehydrogenation of ethylbenzene to styrene. The model was used to extract intrinsic kinetics from the industrial reactor data through a simple iteration technique. The model was then used to investigate the advantages of using selective membranes for the removal of the produced hydrogen from the reaction mixture. The removal of the hydrogen enhanced the forward dehydrogenation reaction and hence improved the overall conversion of the ethylbenzene as well as the yield and selectivity of the styrene considerably. The effect of different design and operating parameters were investigated and an estimate of profit gain was determined. In addition to the intrinsic kinetic data of the industrial catalyst, different intrinsic kinetics parameters obtained by using in-house prepared catalysts in a laboratory reactor were used in the simulation of the reactor with permeable membranes; and their effect on the performance of the reactor was studied. The quantitative predictions obtained using such a rigorous heterogeneous model for the reactor should be reasonable reliable, however they still need to be checked experimentally.
