In this paper, a new type of natural adsorption materials were prepared by spray granulation. The structure and properties of the product were characterized by scanning electron microscope analysis, N2 adsorption desorption analysis, infrared analysis, X ray diffraction analysis, the rmogravimetric analysis. The results showed that: the best preparation conditions of the adsorption materials were as follows: the temperature was 59.21°C, the pressure was 0.28 Bar, and the rate was 14.15 ml/min. In addition, the natural materials had high porosity and specific surface areas , which was better for adsorption. The pore size was mainly concentrated between 13 ~ 28nm. Moreover, these materials had more functional groups. The decomposition temperature was 250°C,which resulted in better thermal stability. Consequently, the materials had better adsorption properties, and the materials will have better application prospect.

Thermal decomposition of -terpinyl--D-glucapyranoside was studied by DTA/SDTG and DSC. The heating rate was 5, 7.5, 10 and 15 K/min, and the samples were heated from the 30 to 500℃, the methods of Friedman and Flynn-Wall-Ozawa were applied to calculate the parameters of thermal degradation. Degradation mechanism was estimated by the methods of Coats-Redfern and Phadnis-Deshpande. TG-DTG curves showed that with the increased heating rate, the mass of -terpinyl--D- glucapyranoside of starting loss T0, the biggest rate of mass loss Tp and final mass loss Tf all have linear increase. So that thermal degradation temperature was mainly influenced by the heating rate B. The DSC curves showed that melting and decomposition proceeded at same time. By Friedman and Flynn-Wall-Ozawa, the activate energy of Ea were 216.63 KJ/mol and 206.18 KJ/mol respectively, with well correlation.
