| Abstract: | Two item exponential equation were used to simulate the process about carbon dioxide and other small molecules desorbing from polyurethane. It concluded that the simulation curves suits the experimental datas very well. Then we calculated the diffusion coefficients of carbon dioxide and the other small molecules in polyurethane according to the simulation equation. The effect of the adsorption temperature and pressure to small molecules' desorption from polyurethane were also researched. |
