Abstract

The main purpose of this project is to find the bestbi-metallic catalyst that gives high conversion of glycerol together with high selectivity towards the production of 1,3- propanediol. However, the catalyst that is selective in the yield of 1,3-propanediol is still much to be developed, since most of the conventional glycerol hydrogenolysis catalysts preferred in producing 1,2-propanediol and ethylene glycol. An abundant amount of glycerol need to be further utilized, by converting this readily available bio-renewable source into valuable chemicals. There are three main steps required in conducting this project which are; i) development of supported bi - metallic catalysts via incipient wetness impregnation method, ii) perform catalysts characterization by using temperature program reduction (TPR), X-ray diffraction (XRD), Fourier Transformed Infrared (FTIR) and Field Emission Scanning Electron Microscopy (FESEM); and iii) perform catalytic testing and analysis where the hydrogenolysis reaction of glycerol is conducted. The analysis is done by using gas chromatography (GC). From the results obtained, Cu - Mn catalyst gives the highest glycerol conversion in the hydrogenolysis reaction with 11.08 % . Meanwhile, for the selectivity towards 1,3-propanediol, Cu - Ce catalyst shows the highest value with 9.70 %. Both conversion and selectivity results of Cu - Ag and Cu - Mn catalyst are comparable, with only a slight difference, andthesetwo catalysts produce more 1,3 - propanediol instead of 1,2 - propanediol. It is believed that, Cu - Ag and Cu - Mn have a high potential to be developed as the catalysts for hydrogenolysis of glycerol to 1,3-propanediol.
