Biodiesel adalah bahan bakar alternatif yang potensial untuk diproduksi secara berkesimbungan. Minyak kelapa sawit salah satu bahan baku yang dapat dikonversi menjadi biodisel. Penelitian ini bertujuan mempelajari pengaruh katalis (NaOH/Ni/γ-Al 2 O 3 ) pada reaksi transesterfikasi minyak kelapa sawit terhadap persentase rendemen biodiesel, densitas, persentase etil ester, serta konversi asam lemak bebas dari produk biodiesel dari minyak kelapa sawit. Proses pembuatan biodiesel melalui transesterifikasi minyak kelapa sawit dengan pereaksi etanol pada suhu 60 o C dengan penambahan katalis NaOH/Ni/γ-Al2O3 . Setelah waktu reaksi yang ditentukan, produk biodiesel didiamkan selama 24 jam ini bertujuan agar terjadi pemisahan antara sisa etanol, dan gliserol. Berdasarkan hasil penelitian dan pengolahan data yang telah dilakukan, produk biodiesel terbaik pada penelitian ini adalah produk dengan persentase katalis 4% dan waktu reaksi 3 jam. Produk biodiesel ini, menghasilkan persentase rendemen sebesar 94,26% dan persentase etil ester sebesar 89,21% dan nilai konversi FFA sebesar 85,28%.
C 15 ) 30,4%, dan biodiesel (C 16 -C 20 ) 28,79%. Perolehan nilai rendemen yang sama juga diperoleh dengan menggunakan katalis HCl/Ni/-Al 2 O 3 (1%) yaitu sebesar 80%; selektivitas terhadap biogasoline (C 5 -C 11 ) 4,51%, biokerosin (C 12 -C 15 ) 28%, dan biodiesel (C 16 -C 20 ) 37,3%.
Fuel oil has a deficit every year. Therefore, a substitute fuel is needed, which can be obtained more efficiently. One of the alternative fuels that have been widely researched is biofuel. Catalytic cracking is a method of producing biofuels such as biogasoline (C5-C9), bioavtur (C10-C15) and green diesel (C16-C22). This research aims to produce biofuels by catalytic cracking of palm oil using HCl/γ-Al2O3 and HCl/Ni/γ-Al2O3 catalysts (1, 3, 5 and 7%). The catalyst was prepared by wet impregnation and characterized by x-ray diffraction, Brunauer Emmett teller and ASTM-D664. The reaction cracking process was operated at a constant temperature of 370 °C, 50 ml volume, and 1 atm pressure. The best catalyst for cracking palm oil is HCl/Ni/γ-Al2O3 (5%) with a yield of 81%, selectivity to biogasoline at 6.41%, bioavtur at 33.81%, and green diesel at 20.33%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
