Upgrading Crude Biodiesel dari Minyak Goreng Bekas menggunakan Katalis H-Zeolit

Crude biodiesel hasil transesterifikasi minyak goreng bekas dapat ditingkatkan kualitasnya melalui proses catalytic cracking menggunakan zeolit alam. Penelitian ini bertujuan untuk menentukan kondisi optimum proses catalytic cracking dan sifat fisika dan kimia biofuel yang dihasilkan. Reaksi dijalankan dalam reaktor dengan memvariasikan waktu (1, 2 dan 3 jam), konsentrasi katalis (3, 5 dan 7 %), ukuran partikel katalis (180, 250 dan 630μm) dan suhu reaksi (325, 350 dan 375°C). Kondisi optimum proses catalytic cracking crude biodiesel didapatkan pada : waktu 3 jam, konsentrasi katalis 7%, ukuran partikel katalis 180 μm dan suhu reaksi 375°C. Biofuel yang dihasilkan mengandung 6,26% fraksi bensin(C5-C11); 17,6% kerosin (C12-C15), 47,73% biodiesel (C16-C20) dan asam lemak 28,4%. Analisis sifat fisik menunjukan densitas 0,9631g/mL, titik tuang 12°C, titik nyala 49°C dan angka oktan 72,6. Kata kunci: catalytic cracking, crude biodiesel, angka oktan, biofuel. Crude biodiesel from transesterification of used cooking oil can be improved in quality through catalytic cracking using natural zeolite. This study aims to determine the optimum conditions for catalytic cracking and the physical and chemical properties of biofuels produced.
