摘要：

A new sulfate oxide solid acid catalyst SO42-/SnO2-Hangjin2# clay was compounded with Hangjin2#clay, activated by sulfuric acid, as a carrier. In the catalysis of Xanthoceras sorbifolium Bunge, using the yield of oil and methanol synthesis of biodiesel as an index, the effect of SOa2-/SnO2-Hangjin2#clay and the preparation conditions on the activity of solid acid were investigated. The variables included in the optimization process were concentration of Sn, impregnation sulfuric acid concentration, and calcination temperature. The optimal conditions were found as 0.4 M SnCla, 3.0 M H2SO4 impregnation, and 350 & DEG;C calcination temperature. The catalyst was examined by scanning electron microscope, X-ray diffraction meter, Fourier transform infrared spectroscopy, surface area, and thermal weight analysis. The results showed that the introduction of Hangjin2#clay in the SO42--SnO2 solid acid catalyst improves its catalytic activity.
