Abstract

Desulfurisasi bahan bakar solar perlu dilakukan untuk mengurangi polusi sulfur di udara. Namun proses desulfurisasi akan menurunkan sifat lubrikasi bahan bakar solar. Untuk mengatasi hal tersebut diperlukan bahan aditif untuk meningkatkan lubrisitas. Lubrisitas bahan bakar solar dapat ditingkatkan dengan adanya senyawa bioaditif seperti hidroksi etil ester (HEE). HEE disintesis melalui reaksi transesterifikasi minyak sawit (trigliserida) dan etilen glikol pada suhu 150 ? selama 5 jam serta katalis K2CO3. Produk yang dihasilkan terdiri dari 2-hidroksietil ester miristat 1.46%, 2-hidroksietil ester palmitat 38.86%, 2-hidroksietil ester oleat 9.99%, 2-hidroksietil ester stearat 8.30%, 2-hidroksietil ester eikosanoat 0.69%, 2-hidroksietil ester lignoserat 2.80%, diester 2-HEE C16:0-2 HEEC16:0 5.68%, diester 2-HEE C18:1-2 HEEC16:0 21.04%, dan diester 2-HEE C18:1-2 HEEC18:2 5.00% serta hasil sampingan berupa asam palmitat 2.46% dan asam oleat 3.72%. Pengaruh lubrisitas terhadap penambahan sebanyak 1% produk bioaditif ke dalam bahan bakar solar pertadex diamati menggunakan instrumentasi High Frequency Reciprocating Rig (HFRR). Hasil pengamatan terhadap penambahan bioaditif, yang memiliki sifat lubrisitas paling baik (DLA=189µm) dan memiliki perbedaan nilai DLA cukup jauh lebih rendah daripada bahan bakar solar pertadex (DLA=279µm). ===================================================================================================== Desulphurization of diesel fuel is necessary to be done to reduce sulphur content in the air. However, the desulphurization process will reduce the lubrication properties of diesel fuel. In order to overcome the problem, it needs bioadditive to improve the lubricity. Lubricity of diesel fuel can be improved by the subsistence of chemical compound that is hydroxy ethyl esther (HEE). HEE will be synthesized through the transesterification reaction of palm oil (triglycerides) and ethylene glycol at 150 °C for 5 hours and K2CO3 catalyst as well. The composition of bioadditive product consist of 2-hydroxy ethyl ester miristic 1.46%, 2-hydroxy ethyl ester palmitic 38.86%, 2-hydroxy ethyl ester oleic 9.99%, 2-hydroxy ethyl ester stearic 8.30%, 2-hydroxy ethyl ester eicosanoic 0.69%, 2-hydroxy ethyl ester lignoceric 2.80%, diesters 2-HEE C16:0-2 HEEC16:0 5.68%, diesters 2-HEE C18:1-2 HEEC16:0 21.04%, and diesters 2-HEE C18:1-2 HEEC18:2 5.00% and by-products as palmitic acid 2.46% and oleic acid 3.72%. The addition of 1% bioadditive product into pertadex diesel fuel using High Frequency Reciprocating Rig (HFRR) instrument has a better lubricity properties (WSD=189µm) and has a widely lower WSD value difference than pertadex diesel fuel (WSD=279%).
