Then, esterification/transesterification reaction was performed with the lipid extracted from sewage sludge to verify the activity of these catalysts. Results showed that the catalysts with n(Al):n(Sn)?=?1:10 prepared by 79?wt% H2SO4 possessed the best physical properties with a large number ...
One-carbon (C1) metabolism is important for synthesizing a range of biologically important compounds that are essential for life. In plants, the C1 pathway is crucial for the synthesis of a large number of secondary metabolites, including lignin. Tetrahy
Catalysts are critical materials for biodiesel production using sewage sludge feedstock.In this research,different SO42-/Al2O3-SnO2 catalysts were prepared and characterized.The catalysts prepared at different conditions were characterized through NH3 adsorption FT-IR and TGA.Then,esterification/...
