Real feeds carbon supported catalysts

Although the primary focus of this review was carbon and carbon-supported catalysts, attempts have been made to identify the difference in the effect of carbon supports compared with the oxidic supports, particularly that of y-Al203. It has been noted that many studies had the same objective. For this purpose, the difference in catalyst activity and stability was estimated using both model compounds and real feeds under variable conditions. The conditions applied during the preparation of carbon-supported catalysts have... 

Information on the hydroprocessing catalysts supported on carbon materials in the patent literature is rather limited. This contrasts with a large number of patents on other carbon-supported catalysts, i.e. automotive, HYD for chemicals production, etc. In most cases, the disclosures of the carbon-supported hydroprocessing catalysts considered real feeds. 

Most of the studies on catalytic activity of the 1st, 2nd and 3rd TMS supported on carbon have been using various model compounds, although to a lesser extent real feeds have also been included in the studies. In this case, the Fe supported on AC have attracted some attention. In recent years, the carbon-supported metal carbides, nitrides and phosphides were also tested as catalysts for hydroprocessing reactions. 

Noble metals (NM) supported on carbons have been tested as catalysts for various model reactions, as well as for real feeds. In this regard, HDS, HDN, HCR and HDO activities were determined. In similar reactions, metal carbides, metal nitrides and metal phosphides supported on various forms of carbon have also been receiving attention.
