“…If the acid value is very high, WCO requires a pre-treatment to decrease its fatty acid content before the conversion to biodiesel to prevent saponification reaction. Previous studies [47][48][49] have suggested that, feedstock FFA content before trans-esterification should be 0.5-1% and higher than 0.5% content of FFA in WCO must be reduced. Table 1 shows that, the waste cooking oil used in the current work had a density of 911 kg m -3 at 15.56°C, kinematic viscosity of 3.321 cSt (centistokes) (1 cSt = 1 mm 2 •s −1 = 10 −6 m 2 •s −1 .)…”

In this study, green biodiesel was produced from Egyptian waste cooking oil by trans-esterification reaction using membrane technology. The produced biodiesel was characterized by physicochemical properties, FTIR, and gas chromatography/mass spectrometry (GC/MS). It was found that it meets the specifications of the American standard test method (ASTM) D6751. Because glycerol was the only impurity that was difficult to separate from the prepared biodiesel by regular methods, polysulfone (PS) membrane and three hybrid membranes were prepared using the phase inversion method for the glycerol purification process. The hybrid membranes were prepared by mixing PS with different weight ratios of polyethylene glycol (PEG), polyvinyl pyrrolidone (PVP), and zinc oxide nanoparticles (ZnO NPs). The structure and surface morphology of the resulted membranes were characterized by scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), and thermal gravimetric analysis (TGA). The purification efficiency of these membranes was satisfied by highperformance liquid chromatography (HPLC) and weight loss ratio. The HPLC chromatogram showed that the membrane of the PS/ZnO NPs provided the highest separation rate of the biodiesel by-product glycerol compared to the other ones.

“…Biodiesel is an alternative energy source that can be produced from animal fats and vegetable oils [2]. It presents excellent characteristics when compared to petrodiesel and can be directly used in regular diesel engines [3]. Compared to petrodiesel, biodiesel shows no sulfur emissions and a higher cetane number, lubricity, and flash point.…”

The production of biodiesel from refined sunflower vegetable oil over basic CaO/ZSM-5 catalysts was investigated. Several catalysts with various loadings of CaO on ZSM-5 were prepared, calcined at 800 °C, and characterized by N 2 adsorption-desorption, X-ray diffraction, Fourier transform infrared spectroscopy, and CO 2 -temperature-programmed desorption techniques. Calcined catalysts were tested in the transesterification reaction and reaction conditions were optimized by varying the catalyst-to-oil ratio and reaction time. The most active catalyst was the CaO/ZSM-5 catalyst with a 35 wt % loading which gave the highest fatty acid methyl ester yield. The high catalytic activity was attributed to the active basic sites generated following CaO addition. Furthermore, the catalyst demonstrated stability against the leaching process.

“…Normally the energy consumption is reduced for the alcohol having high carbon chain. This is considered as disadvantage of process for limitation in alcohol selection for favoring energy conservation 15 . Researcher reported that high mass transfer resistance in some esterification processes is the possible reason that makes them energy inefficient.…”

This paper focuses on the optimization of energy consumption in esterification of acetic acid wherein the water removal is achieved by using silica gel desiccant in a microcontroller based automated reactor. Esterification reactions are endothermic hence, one can get more product, by increasing the temperature, thus disturbing the equilibrium. Heat of reaction (Hr) was estimated by using the heat capacity data and constants (C). Energy analysis and modelling was developed for the enhancement of process which is the key component of the systems. The mathematical model is validated by experimental results. In this paper, effect of parameters like desiccant weight, regeneration temperature and molar ratio on energy consumption are studied. Trends of energy effectiveness of several parameters are presented in the various regeneration temperatures and molar ratio and desiccant weight which confirmed the linear relationship with hot air flowrate. Decrease of 33% in power consumption was observed by decreasing the hot air flowrate by 10%.This is the conformity of validation of affinity law. The newly invented model was optimized for variables, hot air temperature, molar ratio and silica gel weight. The minimum energy consumption at 1 desirability was reported by software in the given range of parameters. When the hot air temperature, molar ratio and silica gel weight were 67.670C, 3 and 34.32 gm, then the minimum value of energy consumption was 29.59 Watt.
