FUEL SYNTHESIS OF SYNGAS USING HYDROTALCITE DERIVED CATALYST

Abstract

This project investigates the fuel synthesis from syngas using hydrotalcite derived catalyst. The focus of this research is syngas conversion into methanol as an alternative source of fuel. Hydrotalcite derived catalyst was used as it is flexible to reform its structure and have been demonstrated its best performances as catalyst. The range of hydrotalcite derived catalyst will be prepared via co-precipitation method with the aid of metal precursors of nickel, zinc with alumina as support. Hydrotalcite derived catalyst of Ni-Al, Zn-Al and Ni-Zn-Al will be tested throughout this study. The physicochemical and catalytic properties of catalysts was studied usingRAMAN Spectroscopy method, Brunauer-Emmett-Teller (BET) method and Field Emission Scanning Electron Microscopy (FESEM). Catalytic performance of synthesized catalyst was tested using a hydrocarbon cracking reactor to synthesize syngas into methanol. The desired temperature and pressure for this project was fixed at 200℃ and 2 bar respectively. From the overall catalytic reaction, it proves that Zn-Ni-Al has the highest yield of methanol production compared to 2 other bimetallic catalysts. Thecomposition of feed gas used was CO/H2/N2used was 35/45/20
