Transesterification of coconut oil for the production of biodiesel using sulfonated multiwalled carbon nanotubes_(MWCNTs)

Transesterification of coconut oil for the production of biodiesel using sulfonated multiwalled carbon nanotubes_(MWCNTs) / Chang Kim Ho
Kumpulan sulfat telah dicangkukkan ke atas permukaan permangkin multi dinding nanotiub karbon (MWCNTs) untuk funsionalisasikan MWCNTs bagi menghasilkan biodiesel daripada minyak kelapa dengan pempolimeran in situ 4- stirenasulfonat. MWCNTs tersebut telah disifatkan oleh Mikroskopi Elektron Penskanan dengan Mikroanalisis X-ray (SEM & EDX), Spektroskopi Inframerah Transformasi Fourier (FTIR), Brunauer-Emmett-Teller (BET) luas permukaan, Desorpsi Terancang Suhu (TPD) dan Spektroskopi Ultraviolet-nampak (UV-vis). MWCNTs yang telah disulfonasikan ini menunjukkan kestabilan dan ketertaburan yang tinggi. Tindak balas transesterifikasi minyak kelapa telah dijalankan dalam reaktor bertekanan pada keadaan berikut:. Suhu tindak balas iaitu 170 ºC, 4 jam masa tindak balas, nisbah metanol kepada minyak ialah 20, dan beban pemangkin iaitu 2 peratus mengikut berat. Pemangkin tersebut menunjukkan prestasi tinggi dalam pengeluaran biodiesel dengan penukaran 62.38 %. Berdasarkan keputusan dalam projek penyelidikan ini, nampaknya MWCNTs yang telah disulfoansikan ini mempunyai potensi untuk menjadi satu teknologi baru dalam industri pengeluaran biodiesel. _______________________________________________________________________________________________________ Sulphate groups were grafted onto the surface of multiwalled carbon nanotubes catalysts (MWCNTs) to functionalize MWCNTs for producing biodiesel from coconut oil by in situ polymerization of 4-styrenesulfonate. The resultant sulfonated MWCNTs were characterized by Scanning Electron Microscopy with Xray Microanalysis (SEM & EDX), Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) surface area, Temperature-programmed Desorption (TPD) and Ultraviolet-visible (UV-vis) Spectroscopy. The sulfonated MWCNTs show stable and high dispersibility. The transesterification reaction of coconut oil was carried out in a pressurized reactor at the following conditions: reaction temperature of 170ºC, reaction period of 4 hours, methanol to oil ratio of 20, and catalyst loading of 2 wt.%. The catalyst showed high catalytic performance in biodiesel production with the conversion of 62.38 %. Based on the findings in this research project, the sulfonated MWCNTs seem to have a potential to be a breakthrough technology in the biodiesel industry.
