We have studied the preparation of unsupported and lignite supported β-Mo 2 C using MoCl 5 as precursor. The catalysts were characterized by XRD and TEM techniques and tested in the reaction of propene hydrogenation at room temperature and pressure. Total carburization was observed at 923K and although incomplete, carburization also occurred at 473 or 723K. The high temperature supported...
New composite materials with application to catalyst supports or adsorbents are presented. They are made of compressed expanded graphite of various densities first impregnated by polyfurfuryl alcohol and next pyrolyzed and activated. The resultant materials are monoliths comprising a graphite backbone coated by a thin layer of active carbon. The electrical conductivity and the dynamic elastic moduli...
The present work is devoted to the study of the role of MoCl 5 and its by-products on reactions involved in pore formation during the preparation of activated carbon for the manufacture of carbon-supported catalysts. The carbonaceous precursors were a coal tar pitch and three bituminous coals of increasing rank. Continuous detection of evolved tar and gas during carbonization was implemented...
The electrical conductivity of various kinds of charred anthracites has been systematically studied as a function of their heat treatment temperature. Concurrently, volume and mass variations of several samples of these materials were measured after each calcination. From these results and based on a simplified picture of the structure of ideal anthracites, we propose to quantitatively explain the...
