Abstract

This research title is Fischer-Troprch(FT) Synthesis Of Hydrocarbon Over Mesoporous Co/SBA- 15 Catalyst:Influence Of Cobalt And Zinc Precursors Loading.The FT process is a set of chemical reaction that convert mixture of carbon monoxide and hydrogen into liquid hydrocarbons.The objectives are about to synthesis S B A- 15 mesoporous silica,to synthesis Co - Z n/ SB A- 15 mesoporous catalyst and to determine the influence and effect of promoter on the catalytic properties.The synthesis of Co- Z n/SB A- 15 catalystis prepared by an impregnation method.Cobalt nitrate and Zinc nitrate will be used as precursors and promoter respectively and being introduced as metal to the catalyst.Fourier Transform Infrared (FTIR) isused to identify types of chemical bonds in the catalyst where then Si-O- Si functional group is detected because of the present of silica from Tetraethyl-orthosilicate,TEOS.Themorphology of the catalyst surface determined by Scanning Electron Microscope( SEM) and it is analyzed that the catalyst to have'rope-like' structure and no change in morphology after modification.After Cobalt and Zinc is added,X-ray Diffraction (XRD) has detected that there are cobalt crystalline formed and the amorphous shape graph of Pure SBA15 is changed with new peeks detected due to intensity changes.The best BET surface area analyzed is 375.9021m2 /g by the sample of 10% Co 15% Zn-SBA15 catalyst which also poses big pore volume of 0.480953 cm3 /g.Thermogravimetric Analyzer (TGA) measured the decomposition of the samplesat temperature of 100°C, 250C, 300C and 450C which caused by decomposition of adsorbed water,organic functional group, dehydroxylation of silicate and nitrate group respectively.Thus,with all revenues collected from all the tests and compared with previous studies, this study found to be one small achievement in the catalyst industry.
