Abstract

Proses desulfurisasi pada bahan bakar solar dapat mengurangi sifat pelumasan bahan bakar tersebut, sehingga dapat mempercepat keausan pada mesin injeksi bahan bakar. Pada penelitian ini telah dilakukan sintesis senyawa bioaditif peningkat lubrisitas etilen glikol ester melalui reaksi transesterifikasi minyak kedelai dan etilen glikol, menggunakan katalis K2CO3. Karakterisasi produk bioaditif dilakukan dengan menggunakan Kromatografi Gas - Spektrometri Massa (KGSM). Hasil analisa KGSM menyatakan bahwa produk bioaditif berupa campuran antara etilen glikol monoester/2-hidroksietil ester (HEE) dan etilen glikol diester (EGD). Senyawa etilen glikol monoester terdiri dari HEE palmitat, HEE stearat, HEE oleat, HEE linoleat, HEE linolenat, HEE eikosanoat dan HEE dokosanoat. Etilen glikol diester merupakan campuran dari EGD (C16:0 dan C18:2), EGD (C16:0 dan C18:3), EGD (C18:1 dan C18:3) dan EGD (C18:3 dan C18:2). Produk bioaditif yang telah disintesis kemudian dianalisa lubrisitasnya pada saat ditambahkan pada bahan bakar solar jenis pertadex menggunakan metode High Frequency Reciprocating Rig (HFRR). Hasil analisa HFRR meenunjukkan bahwa penambahan 1% bioaditif HEE ke dalam pertadex dapat meningkatkan lubrisitas dari pertadex secara signifikan.

The desulfurization process in diesel fuel can reduce the lubricating properties of the fuel, thus accelerating wear on fuel injection machine. In this research, a bio-additive lubricity improver, 2-hydroxyethyl ester (HEE) has been synthesized through the transesterification reaction of soybean oil and ethylene glycol using a K2CO3 catalyst. Characterization of bio-additive product was carried out using Gas Chromatography - Mass Spectrometry (GC-MS). The results of the GC-MS analysis stated that the bio-additive product was a mixture of ethylene glycol monoester / 2-hydroxyethyl ester (HEE) and ethylene glycol diester (EGD). The ethylene glycol monoester compound consisted of HEE palmitate, HEE stearate, HEE oleate, HEE linoleate, HEE linolenic acid, HEE eicosanoate, and HEE docosanoate. Ethylene glycol diester is a mixture of EGD (C16:0 and C18:2), EGD (C16:0 and C18:3), EGD (C18:1 and C18:3), and EGD (C18:3 and C18:2). The synthesized bio additive product was then analyzed for its lubricity when added into pertadex diesel fuel using the High-Frequency Reciprocating Rig (HFRR) method. The results of the HFRR analysis show that the addition of 1% HEE additive to pertadex diesel fuel can significantly increase the lubricity of pertadex diesel fuel.
