摘　　要：以纸浆污泥生物炭为载体制备固体碱催化剂,并将其应用于生物柴油的制备。催化剂的物理化学性质通过热重分析(TG)、扫描电子显微镜及X射线能谱分析(SEM-EDS)、傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、N_(2)吸附/脱附和CO^(2-)TPD进行表征。结果表明:由于30K/PPSB-600催化剂的总碱度最高,具有非常好的的催化性能(生物柴油最大产率为98.5%)。此外,对催化剂的稳定性和利用周期性进行多次实验。通过8次回收实验后,新催化剂仍具有较高的催化性能(生物柴油产率为80%),其中少量失去催化活性的原因是K^(+)的流失。In this paper,pulp&paper sludge biochar is used as a carrier to prepare a solid base catalyst and applied to the preparation of biodiesel.The physicochemical properties of the catalyst were analyzed by thermogravimetric analysis(TGA),scanning electron microscope&energy dispersive spectrometer(SEM-EDS),Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),N_(2)adsorption/desorption and CO^(2-)TPD for characterization.The results show that 30K/PPSB-600 has the highest total alkalinity,and it has excellent catalytic activity(maximum biodiesel yield is 98.5%).In addition,the stability and reusability of the catalyst were also examined.After 8 times of repeated use,the catalyst still has high catalytic activity(biodiesel yield is 80%).The small amount of catalyst deactivation is mainly due to the loss of K^(+)ions.
