“…To fully develop the potential biodiesel as an alternative fuel and polish its exhaust emissions property, such as smoke, CO and HC, researchers attempted to increase the oxygen content by introduction of ester groups into the molecules to reduce engine-out exhaust emissions. [4][5][6] Recently, a kind of novel biodiesel, which was synthesized by the transesterication reaction of FAMEs with short chain glycol ethers mainly using homogeneous base catalysts, 5,6 has attracted more attention. Similar to the production of the conventional biodiesel, the usage of homogeneous catalysts could corrode the equipments easily, and create large amounts of caustic wastewater giving rise to high production cost and serious environmental pollution.…”

A series of KF-modified Ca-Al hydrotalcite (xKF/HTL-M) solid base catalysts was prepared in methanol, and characterized by thermogravimetry analysis (TG-DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and carbon dioxide temperature-programmed desorption (CO 2 -TPD). The catalytic activity was investigated in the transesterification of ethylene glycol monomethyl ether (EGME) with methyl laurate (ML) to produce a novel biodiesel of ethylene glycol monomethyl ether monolaurate (EGMEML). The effect of the mass content of KF and the main reaction parameters such as EGME to ML molar ratio, amount of catalyst, reaction time and temperature on the yield of EGMEML were examined.The results indicate that a new phase of KCaF 3 formed in xKF/HTL-M, and acted as the main active sites for the transesterification. In addition, xKF/HTL-M has excellent catalytic performance in the production of EGMEML. The highest yield of 97.7% was obtained over 24.7KF/HTL-M at EGME/ML molar ratio of 3.0, catalyst amount of 5 wt%, and reaction time of 4 h at 120 C. Moreover, the catalyst displays a good stability and reutilization. A satisfactory yield of 90% was obtained after use for five consecutive cycles without significant deactivation. Finally, the activation energy (E a ) of the reaction of EGME with ML over 24.7KF/HTL-M was obtained as 27.11 kJ mol À1 .

“…Meanwhile ethylene glycol ethyl ether and propyl ether types biodiesels and diethylene glycol and triethylene glycol monomethyl ether types of biodiesels were developed to understand their effects. Table 1 lists some of new types of biodiesels and their fuel properties our group developed in recent years [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. The new types of biodiesels have a CN around 70, oxygen content about 17%, which are higher than FAME.…”

Biodiesel is regarded to be a renewable, CO2 neutral and thus sustainable biological alternative diesel fuel. With attention to the reduction of petroleum import, PM 2.5 aerosol particles and the greenhouse effect gas CO2, biodiesel has drawn great research interests and efforts in the past decade in China. Generally, biodiesel refers to fatty acid methyl ether (FAME) which has a proved effect in reducing diesel emission, particularly PM. However, FAME has a limited cetane number and oxygen content, to study the effects of elevated cetane number and oxygen content on fuel properties, engine combustion and emissions, ethylene glycol monomethyl ether is used to produce a series of new models of biodiesels by transesterification method. The feedstocks are rapeseed oil, soybean oil, peanut oil, palm oil and cottonseed oil. Ether group alcohols used in this study include ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, propylene glycol monomethyl ether, diethylene glycol monomethyl ether, triethylene glycol monomethyl ether. The molecular structure was proved by FT-IR and NMR analyses. Fuel properties were measured based on the corresponding standards. The developed new model biodiesels have cetane number (CN) over 70 and oxygen content over 17% by mass, which are higher than FAME (50 CN and 11% oxygen). They have the same level of lower heating value as FAME, but have a higher density, which helps to compensate the decrease of engine power. Meanwhile, the engine tests were carried out to investigate the effects of ether ester group on engine combustion and emissions. The test results show that FAME reduced smoke 30% to 50%, while the new model biodiesel fuels reduced engine smoke as high as 80% and have the potential to decrease engine HC, CO and NOx emissions 50% or more.

“…The consumption of world petroleum reserves together with ever-increasing environmental concerns have stimulated the search for substitute renewable fuels that can realize the increasing demand for energy (Narasimharao and Wilson, 2007;Yang et al, 2014;Cai et al, 2015). Biodiesel is produced by a transesterification reaction in which triglycerides, vegetable oil or fat reacts with an alcohol in the presence of an alkaline catalyst (Li et al, 2012). Biodiesel is produced by the transesterification of long-chain fatty acids obtained from edible oils, non-edible oil and animal fat with alcohols the presence of an appropriate catalyst (Ma et al, 2017).…”

Silk cotton seed kernel oil is given as a new source for methyl ester synthesis. Crude silk cotton oil was used as feedstock raw materials for methyl ester production using dimethyl carbonate as solvent and KOH catalysis. The maximum methyl esters yield produced as 97% with a kinematic viscosity (4.25 ± 0.2 5 mm 2 /sec) was reached at 80 °C by boiling a mixture of dimethyl carbonate (DMC) and oil mole ratio as 8:1 with 1.5 wt.% KOH catalyst (oil weight based) for 75 min. The produced products were analyzed using gas chromatography-mass spectrometry to identify the methyl esters. The properties of the methyl esters from silk cottonseed kernel oil produced met the specifications of ASTM for methyl esters. The kinetics of the KOH-catalyzed transesterification of diglyceride (DG) and triglyceride (TG) with DMC were studied at 40 to 90 °C. We found that the activation energies for transesterification of diglycerides and triglycerides were 89.8 and 83.3 kJ/mol, respectively. The results showed that all the reaction variables studied had beneficial effects.
