Abstract
Two important types of metal oxide nanoparticle catalysts Copper (II) oxide (CuO) and Cerium oxide (CeO2) are prepared by a suitable method which was traditional precipitation (PT) method at calcination temperature of 400oC for 5h and used for the synthesis of glycerol carbonate GC (C4H6O4) from the direct reaction by the carbonylation of Glycerol GL (C3H8O3) with Carbone Dioxide. The precipitation (PT) was an important route for the preparation of nanoparticles catalyst. The effects of performance of (CuO and CeO2) nanoparticle catalysts on the conversion of glycerol GL, yield of glycerol carbonate GC, selectivity of glycerol carbonate are researched. XRD, XPS, BET, FT-IR, CO2-TPD, H2-TPR are used for the characterization of the prepared catalysts. Comparing the optimal performance between them under reaction conditions were 150 oC, 4MPa (40 bar.), 5h, and both CuO and CeO2 catalyst amount 37.6 % (based on ratio of glycerol weight) by using 2-pyridinecarbonitrate (C6H4N2) as dehydrating agent and dimethylformamide (DMF), (C3H7NO) as solvent. The glycerol conversion (XGL), glycerol carbonate yield (YGC) and glycerol carbonate selectivity (SGC) over 0.7g CuO are 57.151%, 47.524%, and 83.156%, respectively, and glycerol carbonate yield over 0.7 CeO2 is 36.2185% or 35.076%, and the yield of GC could reach as high as 78.234% over 1.73g CeO2, the both catalysts could be easily regenerated by washing with methanol and water after a reaction and then dried at 60 oC overnight after that calcination at 400 oC for 5h without loss of activity after five recycling times, In addition to, the (ICP- MS) results confirmed that the leaching of CuO and CeO2 was below the detection limit.
