Abstract
Co-Mo/Graphene composite synthesized for the first time through the spray pyrolysis method and applied as an HDS catalyst to produce a sulfur free Naphtha feed. The major advantage of the spray pyrolysis technique was its concurrent capability of the in-situ and simultaneous Co-Mo deposition upon the graphene. The produced material was characterized through the XRD, BET-BJH, FTIR and Raman spectroscopy as well as; the NH3-TPD, TPR, TEM and FESEM techniques. The prepared catalyst showed unique properties such as; high degree of total acidity of 5.1 (vs. the usual 0.2–2.0) mmole NH3/g-cat and a relatively high surface area of 705 vs. 189 m2/g of the commercial material. Furthermore, the...
