چکیده مقاله:
In this work cobalt manganese oxides are prepared using a new procedure and studied for the conversion of synthesis gas to light olefins (ethylene and propylene). Catalyst has been prepared from precursor of [Mn(bpy)3][Co(dipic)2].18H2O supported on silica. [Mn(bpy)3][Co(dipic)2]/ SiO2 was calcined at 773 K for 5h. The activity and selectivity of prepared catalyst have been studied in a fixed microreactor under atmospheric pressure in a range of reactor temperatures using synthesis gas with different H2:CO molar feed ratios. Bimetallic complex of [Mn(bpy)3][Co(dipic)2].18H2O and Co-Mn-SiO2 catalyst were characterized by FT-IR, uv-vis, elemental analysis and atomic absorption spectroscopy and XRD, SEM, BET specific surface area and thermal analysis method.
