Waste lubricating oil has been reclaimed by treatment with commercial sulphuric acid followed by adsorption on fuller's earth. A maximum yield (75%) of reclaimed oil at acid- oil ratio of 10:100 with addition of 10% (w/v) fuller's earth has been obtained. Properties of reclaimed oil such as viscosity index, pour point, colour etc. have been improved from 93.4, +2, 5.0 to 109, -10.5, 4.0 by addition of certain proportion of additives. TGA analysis of waste lubricating oil, reclaimed oil and fresh lubricating oil has also been studied. The reclaimed oil obtained after addition of different types of additives is very comparable to SAE 30 grade lubricating oil in terms of properties and is applicable as a standard lubricant. Such a reuse of waste lubricating oil, in addition to its economic effect will help to reduce environmental problem. Key words: Lubricating oil, TGA analysis, Envirormentl problem and Vscosity index.      doi: 10.3329/bjsir.v43i4.2243 Bangladesh J. Sci. Ind. Res. 43(4), 529-536, 2008

Purpose – The purpose of this paper is to prepare novel types of copolymers and terpolymers depending on jojoba, and using them as additives for lubricating oil. Design/methodology/approach – Copolymerization of 1 mole of jojoba with 2 moles of vinyl acetate and copolymerization of 1 mole of jojoba with 2 moles of vinyl pyrrolidone were carried out. Then, two series of terpolymers were prepared by reacting (jojoba: vinyl acetate: alkylacrylate) and (jojoba: vinyl pyrrolidone: alkylacrylate), using free radical chain addition polymerization. Elucidation of the prepared polymers was carried out by using Fourier transform infrared spectroscopy, proton nuclear magnetic resonance and gel permeation chromatography, for determination of weight average molecular weight. The thermal stability of the prepared polymers was determined. The prepared polymers were evaluated as viscosity index improvers and pour point depressants for lubricating oil. Findings – It was found that the viscosity index increases with increasing the alkyl chain length of alkylacrylate. The effect of the monomer type was studied, and it was found that the polymers depending on vinyl acetate have great effect as viscosity index improvers and pour point depressants for lubricating oil. Originality/value – The polymerization of jojoba as different copolymers and terpolymers was carried out. The great influence of the prepared additives on modification of the viscosity properties and pour point of the oil was observed.

Waste Cooking Palm Oil

The use of vegetable oils as a renewable source for the production of ecofriendly biolubricant is gaining the attention of the renewable energy researchers and lubricating oil producers. This study evaluates the quality assessment parameters of ecofriendly biolubricant from waste cooking palm oil (WCPO). The crude WCPO was filtered, centrifuged at 500 rpm, and dried over Na2SO4 crystals overnight. The quality assessment parameters of the pretreated WCPO (PWCPO) were determined to authenticate its potential for the production of multigrade lubricating oils. Kinematic viscosities at 100°C (8.26±0.03 cSt) and 40°C (36.98±0.01 cSt) were determined according to ASTMD-446 method, while the viscosity index (208±0.11) was determined according to ASTMD-2270 method. A design of experiment (Mixture Design Method using Minitab 17) was used to determine the proportion of PWCPO (68.75%), SN 500 (23.75%), and additives (7.50%) that gave the mixture with the optimum quality parameters of the produced biolubricant. The produced biolubricant had kinematic viscosities at 100oC (10.72±0.13 cSt) and 40°C (59.32±0.20 cSt) respectively, a viscosity index of 173±0.10, flash point of 234±1.13°C, pour point of -31±0.10°C, acid value of 21.04±1.21 mg KOH g-1, and iodine value of 1.28±1.40 mg I2 g-1. The produced biolubricant has quality parameters that are comparable to available ecofriendly lubricating oil and was also found within standards for engine oils.

   SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that the sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. The hydroisomerization activity of (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane and base oil. All hydroisomerization experiments of n-decane were achieved at a fixed bed plug flow reactor at a temperature range of 200-275°C and  LHSV 0.5-2h-1.  The results show that the n-decane conversion increases with increasing temperature and decreasing LHSV, the maximum conversion of 66.7 % was achieved at temperature 275°C and LHSV of 0.5 h-1. Meanwhile, the same catalyst was used to improve base oil specification by increasing viscosity index and decreasing pour point. The isomerization reaction conditions, employed are temperature (200-300)ºC, the liquid hourly space velocity of 0.5-2h-1, and the pressure kept atmospheric. The present study shows that Pt Zr W/SAPO-11 minimizes the pour point of lubricating oil to -16°C at isomerization temperature of  300°C and LHSV of 0.5 h-1 and viscosity index 134.8.

Penelitian ini bertujuan untuk mengetahui efek dari penambahan minyak kelapa dan sawit terhadap sifat fisik dan tribologi pelumas SAE 40. Vegetabel oil, seperti; minyak kelapa dan sawit, memiliki nilai viskositas indek yang tinggi dan sifat pelumasan yang baik terutama didaerah boundary lubrication jika dibandingkan dengan mineral oil (SAE 40). Hal ini disebabkan karena vegetabel oil memiliki kandungan fatty acids yang tidak dimiliki oleh mineral oil. Keunggulan lain dari minyak kelapa dan sawit adanya sifat yang ramah lingkungan karena mudah terurai di alam dan dapat diperbaharui. Pada penelitian ini sifat yang baik dari minyak kelapa dan sawit ini akan dimanfaatkan sebagai zat aditif pada minyak pelumas SAE 40. Pengujian dilakukan terhadap sifat fisik dan tribology dengan penambahan 5%, 10%, 15%, dan 20% berat dari minyak kelapa dan sawit ke dalam minyak pelumas SAE 40. Pengujian sifat fisik terdiri dari pengukuran viskositas pada temperatur 400C dan 1000C dan viskositas index. Pengujian sifat tribologi untuk menentukan keausan dan koefisien gesek berdasarkan ASTM G99 dengan menggunakan alat uji pin on disk. Dari hasil pengujian diperoleh bahwa dengan penambahan minyak kelapa dan sawit kedalam minyak pelumas SAE 40 terjadi peningkatan viskositas indeks. Peningkatan viskositas indeks sebanyak  17% dengan penambahan 20% minyak sawit. Terjadi perubahan sifat tribologi dengan penambahan minyak sawit, berupa penurunan keausan dan nilai koefisien gesek dibandingkan dengan penambahan minyak kelapa. This study aims to determine the effect of coconut and palm oils as additives to physical and tribological properties of SAE 40 lubricating oil . Vegetable oils, such as; coconut oil and palm oil, have high viscosity index and good lubrication properties, especially in boundary lubrication compared to mineral oil. This is due to vegetable oil having fatty acids that are not owned by mineral oil. The advantages of coconut oil and palm oil are environmentally friendly properties because they are biodegradable and renewable. In this study, the good properties of coconut and palm oils will be used as additives in SAE 40 lubricating oil. Tests are carried out on the physical and tribological properties with the addition of 5%, 10%, 15%, and 20% by weight of coconut and palm oils into SAE 40 lubricating oil. Physical properties testing consists of measuring viscosity at temperatures of 400C and 1000C and viscosity index. The tribological test is to determine wear and coefficient of friction based on ASTM G99 using a pin on disc test equipment. From the test results,  it was found that coconut and palm oils as additives into SAE 40 lubricating oil could increase in viscosity index. The increase of  the viscosity index was 17% by adding 20% of palm oil. There was a change of tribological properties in the form of decreasing on the wear and the coefficient of friction with the addition of palm oil compare to addition of coconut oil.

Nano-WS2(tungsten disulfide nanoparticles)lubricating oil additive, prepared by the nanometer WS2particulates and semi-synthetic engine base oil as raw materials, was added into Great Wall engine oil with different mass ratio. With a contrast study on these oil samples, the results show that it can improve the extreme pressure, antiwear and viscosity-temperature properties of the engine oil effectively by adding a certain amount of nano-WS2additive, and the optimal concentration is 2wt%. The oil film strength, sintering load and viscosity index of this lubricating oil is respectively 1.35 times, 1.58 times and 1.05 times as that of Great Wall engine oil. In addition, when tested under the grinding conditions of 392 N, 1450 r /min and 30 min, the diameter of worn spot reduces 0.018mm, and the average friction coefficients of friction pairs decrease 16.3%, both of which are lubricated by the oil containing nano-WS2additive. Meanwhile, the experiments testify that the tribological and viscosity-temperature properties of the nano-WS2additive are better than that of the Henkel MoS2additive.
