Tribological behaviour of refined bleached and deodorized ...
The coefficients of friction for RBD palm olein and paraffinic mineral oil under each experimental condition were calculated and plotted as shown in Figure 4. An increment of normal load slightly increases the coefficient of friction. In average, RBD palm olein and paraffinic mineral oil have a coefficient of friction of 0.07 and 0.09 ...

The resulting output is then RBD (refined, bleached, and deodorized) palm oil; (2) Fractionation unit: the output from the refinery unit, also called refined palm oil, is crystallized until it becomes a deep white crystal which is called palm stearin, while the separate liquid form with transparent character is called palm olein.

oil using the four ball tribotester. Refined, bleached and deodorized (RBD) palm olein was blended at volumetric ratio ranging from 20 to 80 % with commercial mineral oil. All experimental works were conforming to ASTM D4172. The results exhibit that some blends of RBD palm olein with commercial lubricant oil have lower the wear scar

Figure 1. Moisture of refined, bleached, and deodorized palm oil (RBDPO) aged at 170 ¡ãC under open conditions. 3.1.2. Acidity No clear trend was observed in the acidities for either RBDPO as shown in Figure 2. The acidity of RBDPO A slightly decreased after 7 days of ageing and increased after 14 days. However, the
Production of High Oleic Palm Oils on a Pilot Scale
Refined, bleached and deodorized palm olein (RBD POo) with an iodine value (IV) of 62 was chemically interesterified with methyl oleate (MO) at a ratio of 50:50 (w/w). The reaction was carried out at 110 ¡ãC in the presence of sodium methoxide as a catalyst using a 100-kg pilot scale reactor. Randomization between 15 and 30 min resulted in less free fatty acid (FFA) formation and higher oleic ...

Experimental Evaluation of Refined, Bleached, and Deodorized ...
In the present research, two types of refined palm oil, refined, bleached, and deodorized (RBD) palm olein and RBD palm stearin, were tested as lubricants. The workpiece material was aluminum JIS-A1050. The experiments were carried out at room temperature (22¡ãC). Paraffinic mineral oils with varying degrees of viscosity were tested for comparison.

The purpose of this study was to evaluate the full-chain carbon cycle of oil palm to determine the CE (carbon equivalences), starting from plantation until production of end-user products including RBD (refined, bleached, and deodorized) Palm Olein as a cooking oil and PME (palm methyl ester) as biodiesel fuel.

Initially, refined, bleached and deodorised (RBD) palm olein with mineral oil blends were optimised using the design of experiments procedure from the outcomes of the four ball tribotester. The optimised blend was found to have characteristics that were better or at par with mineral oil. Then, a reciprocating machine was used for verifying the ...
