Sulfur content of diesel fuel has been cut down to ultra low levels by environmental
regulation in many countries with the aim of reducing diesel engine's harmful emissions and …

Commercial hydrotreating catalysts are usually composed of a sulfide active phase,
molybdenum or tungsten sulfide promoted by cobalt or nickel, supported on alumina. Due to …

Porous carbon materials constitute a very flexible set of supports for the preparation of
heterogeneous catalysts. Their physical and chemical surface properties can easily be …

" Although the primary focus of this book is on carbons and carbon supported catalysts, it
also identifies the difference in the effect of carbon supports compared with the oxidic …

The catalytic activities of bulk tungsten and molybdenum oxycarbides,(W 2 C and Mo 2 C)
have been specifically studied in the isomerization occurring during the …

Co3Mo3C, Co6Mo6C and MCM41-supported Co3Mo3C catalyst are prepared by a simple
one-step thermal decomposition method without the conventional temperature-programmed …

The hydrotreating (HT) of Maya crude oil was carried out in a Parr batch reactor, using
alumina-supported catalysts based on NiMo sulfides, carbides and nitrides, which were …

Different carbon black composite (CBC) supported molybdenum carbides were synthesized.
The support was functionalized with nitric acid at different pH of the impregnation solution …

Synthesis of bulk and alumina-supported, Fe-promoted W carbides and nitrides were carried
out by using oxidic precursors with atomic ratios (Fe/(Fe+ W)) varying from 0 to 1. These …

The stability of unsupported W 2 C tungsten carbide and its sulfur resistance during
hydrodesulfurization (HDS) of dibenzothiophene (DBT) are a specificity of W 2 C. This …
