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 hydroxyethyl esther (HEE). HEE is synthesized through the transesterification reaction of palm oil (triglycerides) and 1,2 ethanediol at 150 °C for 5 hours and K2CO3 catalyst as well. The conversion of TG into the products is 72.90%. The characterization using Gas Chromatography-Mass Spectrometry (GC-MS) indicates that the chemical compound in synthesis products comprise free fatty acids, hydroxyethyl esters and by-products. The obtained products can be used as bioadditives to improve the lubricity of diesel fuel.

The desulphurization process of diesel fuel is carried out to reduce the amount of SO2 emissions that can cause acid rain. However, the desulphurization process in diesel fuel not only removes the sulfur compounds but polyaromatic and polar compounds are also eliminated during this process. The loss of these two compounds can reduce the lubricity properties of diesel fuel. Therefore, it is necessary to add an additive compound that can increase the lubricity properties. In this research, 2-hydroxyethyl ester (HEE) was synthesized as an additive to increase the lubricity of diesel fuel. This compound was synthesized through the transesterification reaction of soybean oil and ethylene glycol with K2CO3 as the base catalyst. The composition of the synthesized additives was analyzed using the Gas Chromatography-Mass Spectrometry (GC-MS). Based on the results of GC-MS spectrum analysis, it is known that the 2-hydroxyethyl ester compound has been formed with a yield of 66.5% (relative to the area of the chromatogram peak). The HEE compound obtained is a mixture of 2 hydroxyethyl palmitate, 2 hydroxyethyl linoleate, 2 hydroxyethyl stearate, 2 hydroxyethyl arachidonate, 2 hydroxyethyl nervate, and 2 hydroxyethyl behenate.

Batubara Sawahlunto, Sumatera Barat dianalisis untuk menentukan karakter geokimia organiknya. Batubara diekstraksi soxhlet dengan pelarut diklorometana:metanol (93:7). Hasil ekstrak organik difraksinasi menggunakan kromatografi kolom. Fraksi keton kemudian dianalisis menggunakan Kromatografi Gas-Spektrometri Massa (KG-SM). Analisis fraksi keton batubara Sawahlunto menunjukkan keberadaan senyawa iso dan anteiso-alkan-2-on, dan isoprenoid keton. Senyawa ini diasumsikan berasal dari rantai klorofil-α pada bakteri. Senyawa hopanon dan sikloheksil keton menunjukkan asal usul batubara dari bakteri. Peringkat kematangan batubara Sawahlunto adalah rendah dikarenakan terdapat senyawa hopanon pada batubara Sawahlunto. Proses kematangan batubara juga dapat terhambat jika komponen yang ada pada batubara berikatan dengan oksigen

Penelitian yang dilakukan terhadap biomarka fraksi hidrokarbon alifatik menunjukkan adanya senyawa n-alkana (n-C13 - n-C27); isoprenoid pristana (Pr) dan fitana (Ph); 4,4,8,9,9-pentametildekalina; 4-b-(H)-eudesmana; 8-b-(H)-drimana; 2,3,6,9,9-pentametildekalina dan 8-b-(H)-homodrimana. Pola distribusi kelompok biomarka n-alkana ditunjukkan oleh persebaran unimodal n-C13 - n-C27, yang menunjukkan asal usul senyawa organik sedimen terdistribusi merata berasal dari fitoplankton dan zooplankton, bakteri dan tumbuhan tingkat tinggi. Rasio Pr > Ph merupakan indikator lingkungan pengendapan oksik dengan kadar garam yang rendah. Adanya senyawa 4-b-(H)-eudesmana mengindikasikan senyawa organik berasal dari tumbuhan darat tingkat tinggi konifer yang tumbuh pada zaman Devonian Akhir. Keberadaan senyawa 8-b-(H)-drimana mengindikasikan adanya masukan alga hijau, plankton dan bakteri Botryococcus braunii. Namun tingginya kelimpahan senyawa 8-b-(H)-homodrimana dibandingkan kelompok senyawa sesquiterpena lainnya merupakan indikator senyawa organik yang berasal dari tumbuhan darat tingkat tinggi. Kontribusi biomarka yang berhasil diungkapkan pada penelitian ini menunjukkan bahwa sedimen sumur tua Wonocolo ini adalah unik dan menarik untuk dipelajari lebih lanjut karena senyawa organiknya variatif, berasal dari bakteri, plankton dan tumbuhan darat tingkat tinggi.

The present work aims to study the synthesis of 2-hydroxyethyl esters from castor oil and its lubrication properties, promising as a lubrication bio-additive in low sulfur diesel fuel. This compound has been successfully synthesized from castor oil and ethylene glycol. The oil to ethylene glycol molar ratio was adjusted to 1:10, and the catalyst loading was used at 9% mole oil. Then, the mixture was refluxed for 5 h. The product components were characterized using GC-MS. The standard ASTM method was used to study the kinematic viscosity and lubrication. The product was dominated by 2-hydroxyethyl esters (94.16%), di-ester (1.12%), and cyclic ester (1.92%). The analysis of friction coefficient and wear scar diameter (WSD) using High-Frequency Reciprocating Rig (HFRR) shows the coefficient of friction and WSD of the product better than reference diesel fuel. From the results of this study, the 2-hydroxyethyl ester of castor oil, especially 2-hydroxyethyl ricinoleate, is the main responsible for the lubricating properties. Thus, 2-hydroxyethyl esters of castor oil can be proposed as an alternative bio-additive to improve the lubrication of low-sulfur fossil diesel fuels.

Liquefaction of low-rank coal has been done to optimize the utilization of low-rank coal, which is less economical for obtaining alternative fuel oil. Coal samples were taken from the Bukit Pinang coal mine, Samarinda Ulu, East Kalimantan. Coal was liquefied using the NEDOL procedure at PUSPITEK, Serpong, South Tangerang, Indonesia. This Bukit Pinang coal liquefaction produces five fractions consisting of Naphta, Light Oil (LO), Middle Oil (MO), Heavy Oil (HO), and Coal Liquid Bottom (CLB) fractions. The liquefaction yield was dominated by the HO and CLB fractions (> 50% by weight). The naphtha, MO and LO fractions were fractionated using SiO2 GF254 Thin Layer Chromatography (TLC) plate. It produced aliphatic and aromatic hydrocarbon fractions. Aliphatic hydrocarbon fractions were analyzed using a Gas Chromatography-Mass Spectrometer (GC-MS), while the aromatic hydrocarbon fractions were not analyzed. Mass spectrum studies showed that the components consisted of n-alkanes, isoalkanes (branched alkanes), cycloalkanes and alkyl cycloalkanes. The aliphatic hydrocarbon components resulting from the liquefaction of low-rank coal showed its equivalence with the components that make up fuel oil. Therefore, this coal liquefaction can be suggested as an optimization for low-rank coal, which is less economical.

Character geochemical of Coal in area (pit) Stars Sangatta, East Kalimantan shows that the coal is classified as steam coal with thermal maturity and have low calories (5768 kcal/kg). The coal is melted in the 1L autoclave for 60 minutes at a temperature of 450oC and a pressure of 12 MPa to obtain a product slurry. Fractionation of slurry product based on boiling point using a vacum distillation apparatus 10 mmHg. Fractions obtained include naphtha, light oil, middle oil, heavy oil and coal liquid bottom. Data show that the weight percentage of the product melting fraction is dominated by heavy oil and coal liquid bottom with percentage of total> 50%. Fraction of light oil in the fractionation further by TLC and the eluent n-hexane in order to obtain an aromatic fraction. The composition of the aromatic hydrocarbon fraction light oil products were characterized using gas chromatography mass spectrophotometer (GC-MS). The identification shows that derivative of kadalen compounds, that is compounds norkadalen (C14H16) which is the fraction of oil that can be potentially as diesel fuel.
