摘要：Mussel shell has been calcined on high temperature. Its main component calcium carbonate isdecomposed into CO 2 and calcium oxide. Calcium oxide is superbase catalyst for the transesterificationreaction. By means of differential thermal balance, the decomposition characteristics of mussel shellhave been studied. And of electron microscope, TEM shows grain morphology characteristics ofcalcination at different calcining temperatures. Organic matter has decomposed during 287°C-458°C.Decomposition of calcium carbonate starts from 600°C to 800°C, when it was balanced. By use oforthogonal analysis, the main influence factors of specific surface area have been optimized. Theoptimal process parameters are 950°C calcination temperature, 120ì m initial diameter and 1 hourholding time.
