“…To the best of our knowledge, this type of catalyst has not been used before for HDC. The literature reports the use of Rh-Al pillared clays for reduction processes both in liquid phase (hydrogenation of acetone [38] or quinoline [39]) and gaseous phase (hydrogenation of CO [40], selective catalytic reduction (SCR) of NO x [41] and catalytic reduction of NO with CO [42,43]). The aforementioned applications suggest the potential of Rh-Al pillared clays as catalysts in reductive processes such as HDC for wastewater treatment.…”

“…Katalizatori su sintetisani na sobnoj temperaturi, atmosferskom pritisku i u acetonskoj sredini. Sn kao promotor se dodaje katalizatorima metodom impregnacije u obliku acetata u različitim procentima [3,8].…”

“…Modifikovani bentonit, PILC's (pillared interlayer clays), sintetizuje se interakcijom katjona prisutnih u interlamelarnom sloju prirodnog bentonita sa neorganskim polioksokatjonima. Posle kalcinacije, polioksokatjoni formiraju odgovarajuće okside koji se ponašaju kao "stubovi" (pilari) između lamela bentonita [1][2][3]. Na slici 1 dat je šematski prikaz transformacije strukture prirodnog bentonita i promena interlamelarnog rastojanja u modifikovanom bentonitu.…”

In this work, the capability of new materials PILC’s synthesized from montmorillonite as support for catalysts based on Rh or Sn promoted Rh has been studied. Rh based catalysts were synthesized by hydrogen reduction at atmospheric pressure for a cationic organo-metallic rhodium complex. The influence of the supports in the incorporation of the active phase has been studied. The catalysts have been tested in the hydrogenation of crotonaldehyde in the vapor phase at atmospheric pressure, analyzing the effect of some working parameters in the formation of the reaction products, namely the temperature of metal reduction, the reaction temperature, and the addition of Sn as a promoter. For comparative purposes, natural clay and commercial silica have also been used as supports. Both the natural clays and the PILC’s materials have resulted adequate supports for the Rh catalysts. The addition of Sn as a promoter modifies the selectivity leading to higher conversion towards crotyl alcohol

Recent Advances in the Control and Characterization of the Porous Structure of Pillared Clay Catalysts

Several methods have been developed and applied in recent years in the characterization of the structure of microporous materials, in general, and of pillared clays, in particular. In the present article, the latest results obtained in the control of the microstructure developed in alumina-pillared clays and various approaches used to the evaluation of the porosity of these materials are reviewed. These include the control of the microstructure developed in pillared clays by adjusting the several parameters involved in the synthesis process, and the evaluation of the porosity of pillared clays. Emphasis is given to the methods to evaluate the pore size and pore size distribution (PSD) of these materials. Two separate sections are devoted to review mathematical modeling studies and 129 Xe NMR spectroscopy of physisorbed Xe to investigate the microporous structural properties of these materials.
