Biodiesel dari Minyak Bintanggur/nyamplung (Challophyllum innophyllum )

  1. PEMANFAATAN KATALIS Ca3 (PO4) 2 DARI TULANG IKAN TUNA PADA PEMBUATAN BIODIESEL DARI MINYAK BINTANGGUR (Callophyllum inophyllum L). Sintesis biodiesel dari minyak bintanggur (Callophyllum inaphyllum L.) telah dilakukan melalui tahap esterifikasi dan transesterifikasi dengan menggunakan katalis Ca3 (PO4) 2 dan pelarut metanol. Proses pembuatan katalis Ca3 (PO4) 2 dilakukan melalui kalsinasi tulang ikan tuna pada suhu 1000ºC selama 2 jam, diperoleh katalis Ca3 (PO4) 2 sebesar 58, 75%, dan dikarakterisasi dengan XRD. Pada proses esterifikasi dilakukan dengan perbandingan mol metanol dan minyak bintanggur 1: 9 selama 2 jam dengan menggunakan katalis asam yaitu H2SO4 sebesar 1, 25%, proses transesterifikasi dengan perbandingan mol minyak bintanggur dan metanol 1: 12 selama 9 jam, menggunakan katalis Ca3 (PO4) 2 10%. Hasil penelitian menunjukkan konversi biodiesel secara teoritis sebesar 73, 76% dan hasil eksperimen sebesar 56, 87%. Hasil biodiesel dianalisis dengan FTIR, GCMS, 1H-NMR, dan ASTM. Hasil uji ASTM meliputi kerapatan spesifik sebesar 0, 9204 g/cm3, viskositas kinematik 29, 68 mm2/s, titik nyala 188, 5 C, titik tuang 6 C, sisa karbon Conradson 0,162%, kadar air 0,175%, dan korosi kepingan tembaga 1b.
  1. Biodiesel Production From Bintanggur Oil (Callophyllum inophyllum L.) Using Calsium Oxide (CaO) Catalyst. The research of the biodiesel from bintanggur oil (Calophyllum inophyllum L.) using calsium oxide (CaO) catalyst had been done. In this study, a two-step process was used to produce biodiesel from bintanggur oil. Initially by esterification process using H 2 SO 4 1.25% catalyst by weight of oil and methanol with a molar ratio of 1: 9 and continued by transesterification process with 1: 12 (oil: methanol) with the catalyst 8 wt% CaO. The esterification and the transesterification process carried out of 2 hours and 7 nespectively at a 65 ÂC. The synthesis of biodiesel was analyzed by FT-IR spectrophotometer. The conversion of biodiesel is 44.49%. The biodiesels properties were caracterized by ASTM method. Results of biodiesels properties there are specific gravity of 0.8878 g/cm 3, viscosity kinematic 5.572 cSt, flash point 176.5 ÂC, pour point 9 ÂC, cooper strip corrosion 1b, and Conradson carbon residue 2.469%.
