吸附相反应技术中物质的吸附和相间分配研究进展

Progress in Adsorption and Distribution of Reactant in Adsorption Phase Reaction Technique

吸附相反应技术是近年来发展起来的主要用于制备纳米复合材料以及纳米催化剂的新型微尺度反应技术。在反应过程中,载体表面吸附层是反应的主要场所,反应物在表面的吸附和在两相间的分配过程决定了反应进行的方式,并影响产物的形态。本文综述了水浓度、温度、吸附质浓度等因素对反应物的吸附过程和平衡吸附率影响,从过程的原理出发,对这些因素的作用规律进行了探讨,形成了较为全面、系统的认识。

Adsorption phase reaction technique developed in recent years is a new type of microscale reaction technology which is mainly used for preparing nano composite and nano-catalyst. In the reaction process, adsorption layer on the support surface is the mainly reaction location, the adsorption of reactant on the SiO2 surface and the distribution process of reactant in two phase determine the mode of reaction and the configuration of product. In this paper, factors （such as water concentration, temperature and reactant concentration） which have effects on adsorption process of reactant and balance adsorption ratio are summarized, the operation rules of these factors are discussed from the basic theory, then we can form full and systemic acquaintance.
