Esterification of high free fatty acids in supercritical methanol using sulfated angel wing shells as catalyst
In this research, shells of Cyrtopleura costata, commonly known as angel wing, were used to prepare sulfated calcined angel wing shell (CAWS) catalysts by a simple, low-cost method. The produced CAWS-SO4 catalyst was characterized by using X-ray diffraction (XRD), Fourier transmission infrared spect...
