“…Sootchiewcharn et al [118] investigated the influence of temperature in the range of 330-370°C on the transesterification of refined palm oil extracted from POME under a pressure of 200 bar and oil-to-alcohol ratio of 1:50. The optimum biodiesel yield of 78.3 % was achieved at 350°C.…”

“…When the temperature was increased to 350°C, approximately 100 % biodiesel yield was achieved. Sootchiewcharn et al [118] investigated the influence of temperature and time on the alcoholysis of refined palm oil extracted from POME. A higher biodiesel yield was achieved by increasing the temperature from 330°C to 370°C, giving the highest fatty acid ethyl ester (FAEE) yield of 63.6 % and biodiesel yield of 78.3 %.…”

Biodiesel synthesis processes including pyrolysis, direct blending, transesterification, and advanced technologies such as microwave-and ultrasoundassisted and supercritical processes from palm oil mill effluent (POME) are reviewed to highlight the significance and advances in terms of process sustainability and cost. POME as the most contaminated waste can be effectively utilized for biodiesel production. Supercritical transesterification offers more advantages over the other processes including higher reaction rate, without catalyst constraint, producing pure glycerol, and simple product separation process. The addition of co-solvents like CO 2 should be investigated for supercritical biodiesel production from POME. Although POME is an inexpensive source to synthesize biodiesel, innovative processes are needed to maximize the oil recovery from POME. Optimization of transesterification parameters is required for high production yields and sustainable processing.

Supercritical transesterification of lipid-based biomasses, a recent technique to produce biofuel without a catalyst, is discussed. This review focused on a glycerol-free process. The supercritical reactants include dimethyl carbonate, diethyl carbonate, methyl acetate, ethyl acetate (ETA), and methyl tert-butyl ether. The by-products from the glycerolfree process can improve both the quantity and quality of the resultant biofuel. This review suggests that supercritical transesterification of lipid-based biomasses using ETA as a coreactant can provide the most valuable advantages, as involves inexpensive and renewable resources, which are important for biofuel production and sustainability.

This work has investigated the reusability of silica-titania in various temperatures (50 – 70°C) of biodiesel production from waste cooking oil. The reused silica-titania catalyst collected from silica-titania catalyst waste produced from the process of separating the catalyst from biodiesel products from palm oil and used cooking oil at various temperatures. The 1st and 2nd reused SiO2-TiO2 were characterized by DR UV-Vis and the spectra were deconvoluted for calculate the fraction of titanium in tetrahedral coordination. In addition the biodiesel products were characterized using FTIR, and several properties of biodiesel such as density, flow rate and acid value were analyzed in order to get the information about catalytic activity reused SiO2-TiO2. The results show the titanium tetrahedral fraction in reused catalyst (1st) and (2nd) are found to be 24,98% and 24.65%, respectively. The FTIR characterization of biodiesel products and waste cooking oil are almost similar. The analysis of waste cooking oil converted to biodiesel shows an optimum temperature of 50oC that at this temperature the lowest density or highest flow rate gave highest conversion of 47.82% using BCR1 and 39.13% using BCR2.
