Equilibrium and Rate Studies in Adsorption and Variable Temperature Stepwise Desorption

这一实验和理论研究项目将获得分子筛上吸附物种的热解吸平衡和速率关系。这些关系式为预测新型分离过程“变温逐级解吸”(VTSD)的动态行为奠定了理论基础。该方法允许通过优先的吸附-解吸循环以顺序方式分离两个或更多被吸附的组分。分离程序是美国在国际市场上最成功的主要行业之一的支柱。因此，分离是最大的能源消耗之一，也是化学制造成本的主要贡献者。未来十年，像VTSD这样的技术可能会对化学工业的效率做出重大贡献。变压吸附(PSA)是一种与VTSD非常相似的过程，它已经为下个世纪先进分离技术的发展做出了重大贡献。VTSD有潜力做出类似的贡献，本质上是对PSA的赞扬。该项目将获得开发和测试VTSD进一步发展所需的数学模型所需的实验数据。

This experimental and theoretical research project will obtain equilibrium and rate relationships for the thermal desorption of adsorbed species from molecular sieves. These relationships are needed to establish a theoretical basis for predicting the dynamic behavior of a novel separation process, "Variable Temperature Stepwise Desorption" (VTSD). The method permits separation of two or more adsorbed components in a sequential fashion through a preferential adsorption-desorption cycle. Separations processes are the backbone of one of the most successful major industries of the United States in the international marketplace. Consequently, separations is one of the largest consumers of energy and a major contributor to chemical manufacturing costs. Techniques like VTSD may make major contributions to chemical industry efficiency in the coming decade. One process very similar to VTSD, Pressure Swing Adsorption (PSA), is already making major contributions to development of advanced separations technology for the next century. VTSD has the potential to make a comparable contribution, essentially serving to compliment PSA. This project will obtain experimental data necessary for developing and testing mathematical models necessary for the further development of VTSD.
