“…After getting the blended fuel, such properties, fuel density (FD) at 15 ºC, kinematic viscosity (KV) at 40 ºC, flash point temperature (FPT), and lower heating value (LHV) were determined, under various ASTM procedures as shown in Table 1. The subsequent results prove that the physical properties of PEE and PME, especially FD, KV and FPT, were in scope of MESS [10,11]. However, these properties were higher and the LHV was lower than diesel.…”

“…A conventional diesel according to diesel standard specifications (DSS) of the Energy Business Department in Thailand was used throughout the test [10]. Palm oil was oleic based which consisted of free fatty acid, 40.06 % palmitic acid, 4.30 % stearic acid, 40.72 % oleic acid and 12.08 % linoleic acid [11]. Bioethanol was analysis-grade anhydrous ethanol (99.9 % purity).…”

“…Purity of PEE was measured by Gas Chromatography (GC) according to EN14103 standard to determine yield of EE. The percentage of PEE was between 98.84 to 99.37 % which was in scope of methyl ester standard specifications (MESS) of this country [10,11].…”

“…Furthermore, another ester gaining more attention in terms of cost benefit and resource availability is EE [10]. Some researchers [10,11] produced palm oil ethyl ester (PEE), transesterified from palm oil, anhydrous ethanol (99.9 % of purity) and catalysts, potassium methoxide and sodium hydroxide (NaOH), and mixed with regular diesel (from 10 to 50 %). The PEE-diesel blended fuels have been operated with high-speed direct injection (HSDI) engines in whole range length of engine loads and speeds.…”

“…CO, THC and BS were reduced, but CO 2 and NO were enlarged with increasing PEE. The production of EE by using NaOH catalyst was frequently examined, because this catalyst was at low cost [11,12]. Earlier studies of EE and EE-diesel blends found that the combining diesel with 25 % cardanol ethyl ester, cardanol oil reacted with ethyl alcohol (99 % purity) and NaOH, exhibited the same engine performance as diesel, but THC and BS were increased [13].…”

Biofuels are an alternative fuel currently being developed to reduce the diesel-engine environmental impact. The release of carbon dioxide (CO2), nitric oxide (NO) and black smoke (BS) becomes an issue derived from diesel engines even in lean-mixture combustion causing an adverse effect to human health. The main aim of the research study is to present the use of biofuels, a mixture of diesel and 10 % palm oil ethyl ester (PEE10) and PEE10 blended with bioethanol from 5 to 20 %, compared with conventional diesel fuel. The biofuels were run on a high-speed direct injection diesel engine at a constant speed of 3,000 rpm under various loads. The use of PEE10 resulted in brake thermal efficiency (BTE) reduction by 2 % and brake specific fuel consumption (BSFC) incrementation by 8 %, but the exhaust emissions were lower than diesel, except for CO2 and NO. However, PEE10 engine performance was better and exhaust gas emissions were lower for both pollutants than diesel mixed with 10 % bioethanol. The investigation of PEE10 with increasing bioethanol revealed that the use of PEE10 blended with 5 % bioethanol (PEE10E5) can improve engine performance, while the BTE and BSFC were close to that of diesel, and exhaust emissions, especially CO2, NO and BS reduced. Moreover, BTE from PEE10E5 fueling increased by 2 % but BSFC was subtle increased, compared to PEE10. On the other hand, the increasing bioethanol from 10 to 20 % in PEE10 led to the more reduction in engine performance, but the engine pollutants were also continuously decreased. Specifically, the blend of PEE10 and 20 % bioethanol indicates that CO2, NO and BS were reduced by 10, 15 and 33 %, respectively, compared to diesel fuel. HIGHLIGHTS A mixture of diesel and 10 % palm oil ethyl ester (PEE10) has less exhaust emissions than diesel blended with 10 % palm oil methyl ester (PME10) PEE10 blended with 5 % bioethanol can improve engine performance, while the brake thermal efficiency and brake specific fuel consumption are close to that of diesel and PME10 The increasing bioethanol from 10 to 20 % in PEE10 leads to the more reduction in engine performance, but the engine pollutants, especially carbon dioxide, nitric oxide and black smoke, are also continuously decreased GRAPHICAL ABSTRACT

Diethyl ether is considered as one of the simplest and lightest oxygenated fuels, which has higher octane and thermal energy than dimethyl ether. Diethyl ether can be considered as one of renewable fuels and is produced by applying a reactive distillation method. Reaction distillation is a complex process in the chemical industry in which the chemical separation and the chemical reaction are carried out simultaneously. In this paper, applying a high purity ethanol dewatering, the process of reactive distillation in the production of diethyl ether is simulated by using Aspen Hysys software. Different models of activity coefficients have been analyzed in this paper. The best model for molecular diethyl ether was found to be one of the most important cases in simulating a diethyl ether unit to obtain a strong thermodynamic model for highly unrealistic behavior of fluid-liquid-vapor balance in this system. Finally, results of simulation with the data are compared and a very good match has been observed.
