Study on the Liquefaction Kinetics of Salix psammophila
摘要
Abstract
In order to study the mechanism of the liquefied reaction of Salix psammophila in alcohols, the dynamic model was applied to show the relationship between the reaction time and the liquefied ratio of Salix psammophila at different temperatures. The results showed that the liquefaction of Salix psammophila in polyhydric alcohols was multilevel and the apparent reaction rate constants went up with the increase of temperatures. Liquefaction activation energy Ea was 7.15×104 J·mol-1 and pre-exponential factor A was 4.1371S-1. According to transition-state theory, the activation free enthalpy(△G), activation enthalpy(△H), and activation entropy(△S) of reaction changed with the increase of temperature. The whole liquefied reaction of Salix psammophila in polyhydric alcohols was endothermic, and the liquefaction system is easily to react when an external energy was input.关键词
