TRANSITION BIMETALLIC CARBIDES: SYNTHESIS AND CHARA CTERIZATION

摘要

Two series of metal transition bimetallic carbides catalysts unsopported and supported on y-Al_2O_3 (Mo and W) from salts sources were prepared by the Volpe and Boudart modified method. The final structural and crystallographic properties were characterized by XRD, BET, TEM, TPD of NH_3 techniques to observe the effect of synthesis conditions. The solids were used as a hydrotreating catalysts in the hydrodesulfurization of thiophene.
