An Experimental Study on the Ignition Behavior of Blended Fuels Droplets with Crude Coconut Oil and Liquid Metal Catalyst

Abstract

This study examines the Ignition characteristics of blended fuel droplets with crude coconut oil and rhodium liquid as a liquid metal catalyst. The ignition behavior was observed by igniting the oil droplet on a junction of a thermocouple, and the droplet evolution recorded with the high-speed camera. The results show that the addition of a liquid metal catalyst successfully reduces the molecular mass of the triglyceride and weakens the bonding force between the carbon chain, and therefore the viscosity and flash point decreases. Moreover, the addition of liquid metal catalysts increased the reactivity of fuel molecules such as C-H, C-C, C = C, and C-O. Changes in the physical properties of the fuel, the geometry of the carbon chain, and molecular mass ease the absorption of heat by the fuel droplet, thereby increasing fuel ignition performances.

Experimental Study on the Effect of Nano Additives γAl2O3 and Equivalence Ratio to Bunsen Flame Characteristic of Biodiesel from Nyamplung (Calophyllum Inophyllum)

“…Nano metal oxides are catalytic while a combustion reaction occurs in the combustion chamber and it increases combustion efficiency [12]- [14]. Nano metal oxides that have been researched as additives to biodiesel include γAl2O3 [15], CeO2 [16], TiO2 [17], ZnO [10], NiO2 [18], Rhodium [19], and SiO2 [20].…”

Utilization of wood waste into briquettes as an alternative fuel substitute for kerosene in Skouw Yambe Village, Jayapura City

“…Hal positif lain yang dapat dihasilkan adalah terciptanya unit-unit usaha mikro yang dapat menambah berpotensi pendapatan masyarakat. Optimisme dari kami terhadap keberhasilan kegiatan ini sangatlah besar, di mana penelitian tentang beberapa jenis bahan bakar alternatif telah berhasil dilakukan dan dipublikasikan pada jurnal internasional bereputasi (Nanlohy et al, 2018(Nanlohy et al, , 2022Nanlohy & Riupassa, 2020). Selain itu pada penelitian awal dalam skala laboratorium telah berhasil dilakukan dan dipublikasikan pada sebuah konferensi internasional di Malaysia pada bulan April 2022.…”

Tips Menyusun Artikel Ilmiah Hasil Penelitian (Original Research Paper) yang Akuntabel bagi Peneliti Pemula

“…Contoh sebuah hasil penelitian yang ditampilkan dalam bentuk grafik, komponen grafik harus lengkap dan dapat dibaca (Purnomo et al, 2020) Gambar 5. Contoh sebuah hasil penelitian yang ditampilkan dalam bentuk photographic view, bagian yang penting ditandai untuk dibahas (Nanlohy et al, 2020) Jika hasil penelitian disajikan dalam bentuk tabel, tabel tersebut harus disajikan dengan rapi dan terorganisir. Hindari garis-garis vertikal dan cukup garis-garis horisontal saja pada header dan penutup tabel.…”
