Figueroa-Diaz, Andrea Belen; Carlos-Hernandez, Salvador; Diaz-Jimenez, Lourdes published the artcile< Crude glycerol/guishe based catalysts for biodiesel production: conforming a guishe biorefinery>, Reference of 112-63-0, the main research area is glycerol guishe catalyst biodiesel production.
Biodiesel production imposes some challenges, such as the crude glycerol management and cleaning requirements of biodiesel produced by homogeneous transesterification. Heterogeneous catalysts based on residual biomass have been proposed to tackle these challenges; in addition, biomass revalorization is fundamental for biorefineries development. In this research, two organic wastes (crude glycerol and guise) are used to synthesize carbonaceous catalysts. Four catalysts, with different crude glycerol/guishe proportions, were prepared by pyrolysis at 800 and 900°C, followed by a chem. functionalization with H2SO4. SEM (SEM), Fourier transform IR spectroscopy (FT-IR), and thermal gravimetric anal. (TGA) were used to characterize the catalysts. The performance of the catalysts was evaluated in a soybean oil transesterification reaction. The crude glycerol/guishe based catalysts lead to similar biodiesel yields than the obtained with a conventional homogeneous catalyst (CH3NaO). The catalyst identified as BS-25-8 (a mixture of 25% guishe and 75% crude glycerol, pyrolyzed at 800°C and sulfonated), in a proportion of 1 wt%, achieved the highest fatty acid Me esters (FAME) yield (99%) in the transesterification reaction, even surpassing the performance of the CH3NaO (yield of 93%).
