Production and Characterization of BWCO
The waste cooking oil and methanol were mixed in a molar ratio of 1:7, and the alkali-catalyzed transesterification reaction was performed at 65 °C for 2h to invented raw BWCO products. When the reaction was completed, glycerin was precipitated at the bottom of the reactor, and the reaction product was on the upper part and maintained for 10 hours to separate. Subsequently, the crude product was washed with deionized water, rotary evaporated, and dried. Finally, biodiesel was obtained. Furthermore, the composition of biodiesel was analyzed using a Gas Chromatography-Mass Spectrometer (Shimadzu GC-MS QP 2010SE). The operating procedures and parameters of the instrument are shown in the Supporting Information.
