Pemanfaatan Batu Kapur Madura sebagai Katalis dalam Pembuatan Bioedesel dari Minyak Nyamplung

Abstract: Pemanfaatan batu kapur dari Pamekasan, Madura sebagai katalis heterogen pada reaksi pembuatan biodiesel dipelajari pada penelitian ini. Batu kapur dikalsinasi pada suhu 900 ºC selama 3 jam untuk membentuk katalis CaO. Katalis CaO yang terbentuk dikarakterisasi menggunakan difraksi sinar-X (XRD), spektroskopi inframerah (FTIR) dan Scanning Electron Microscopy-Energy Dispersive X-Ray Analysis (SEM-EDX). Proses transesterifikasi dari minyak nyamplung dilakukan dengan rasio mol minyak terhadap methanol sebesar 1:… Show more

“…Calcium oxide (CaO) is one of the most studied heterogeneous catalysts due to its excellent activity in transesterification reactions, availability of waste, and low cost, and can be obtained from natural minerals. CaO catalysts are generally produced from the decomposition of calcium carbonate (CaCO3) at high temperatures between 600 and 1000 °C [28], [29]. CaCO3 can be extracted from many natural substances or materials such as chicken eggshell [30], fish bone [31], and limestone [32].…”
