Hydrochlorination of acetylene using supported bimetallic Au-based catalysts

Enhancement of the Stability of Au-Cu/AC Acetylene Hydrochlorination Bimetallic Catalyst with Melamine Treated Support

This paper highlights the experimental and theoretical studies on the Melamine treated Active Carbon (MAC) support for an Au-Cu bimetallic catalyst in acetylene hydrochlorination reaction. Compared to the original Active Carbon (AC) loaded with the same amount of 0.1wt% Au and 1.0wt% Cu,  MAC supported catalyst(MACH), wherein Carbon/C6...

Characterization of Au species in Au/C catalysts for the hydrochlorination reaction of acetylene

A set of Au/C catalysts for the gas phase hydrochlorination of acetylene to vinyl chloride monomer were prepared using a range of strong acids as impregnating solvents and varying the preparation drying temperature. The most active catalyst is the material prepared using aqua regia as solvent with an intermediate drying temperature of 140 C. The effects of the catalyst preparation parameters on...

Aqua regia activated Au/C catalysts for the hydrochlorination of acetylene

Enhanced Oxygen Activation over Supported Bimetallic Au-Ni Catalysts

Modifications of the metal and support during the deactivation and regeneration of Au/C catalysts for the hydrochlorination of acetylene

The effect of gold oxidation state and carbon structure on the activity of Au/C catalyst for the hydrochlorination of acetylene was investigated by a combined approach using TPR, XPS and porosimetry determinations. The activity of the catalyst in the synthesis of vinyl chloride monomer was found to be dependent from the presence of Au 3+ species into the catalyst. However, by preparing catalyst...
