“…A Co-Mo catalyst prepared on a high surface area Sic sample (200 m2/g) showed the same activity for thiophene HDS at 1 atm than a comparable silica-supported catalyst. However, both were about six times less active than a commercial Co-Mo/A120g catalyst with the Same composition (154). The TPR spectrum of the Sic-supported catalyst could be explained by a superposition of the TPR spectra of crystalline Moo3 and Co-Mo/Si02, pointing out the poor interaction of the Co-Mo phase with the carrier.…”

INTRODUCTIONThe hydroprocessing technology was first developed in Germany by BASF in the 1920s, for hydrogenation of brown coal tar in one step into gasoline without coke formation. It was found that cobalt, molybdenum and tungsten sulfides were especially active catalysts (1). Later a low-temperature " T H " process was developed for the same reaction, using activated alumina supported catalysts containing either 10% Mo03-3% NiO or 27% WS23% NiS. The very same compositions are still used today in many commercial hydrotreating (HDT) catalysts! During the development of these catalysts, the effect of various oxide supports on the cracking of gas oil was studied. The following order of cracking activity was found :

“…Leclercq et al have obtained WC crystals with low specific surface area by reaction between tungsten metal and carbon at still higher temperature (1790 K) (2). Ledoux et al also prepared Mo C at very high temperature 1520-1570 K, by reaction between the transition metal vapor oxide and a very high specific surface area active carbon (8)(9)(10). All these previous papers have shown it is possible to use carbon to prepare early transition metal carbides.…”

“…Recently, monolithic foam catalyst support has been researched [16,17]. The crystallized silicon carbide (SiC) exhibits a high thermal conductivity, a high resistance towards oxidation, and chemical inertness, which are necessary for a good heterogeneous catalyst support.…”

Carbon dioxide reforming of methane to synthesis gas has been investigated with Ni catalysts supported on monolithic foam SiC, which were prepared by the initial wetness impregnation method. The catalyst of 7 wt%Ni/ SiC was verified to be the best one in different Ni content catalysts. Compared with other catalysts such as 7 wt%Ni/ SiO 2 and 7 wt%Ni/Al 2 O 3 , the 7 wt%Ni/SiC catalyst exhibited not only the highest activity but also remarkable stability and excellent coke resistance during 100 h reaction. Furthermore, the conversion of CO 2 and CH 4 remained at about 96% and 94%, respectively in 100 h reaction time. The structure and properties of the catalysts were characterized by BET, XRD, H 2 -TPR, XPS and TEM techniques.
