Wankat博士。本研究将探讨一种新的吸附柱再生方法。该方法利用热的纯吸附质蒸气加热色谱柱。当吸附质蒸气在吸附剂上凝结时，蒸汽中可用的潜热用于加热塔。使用冷惰性吹扫气体将吸附物从热床中吹出。与普通的蒸汽再生不同，加热和净化步骤是分离的。通过冷凝从吹扫气体中回收纯吸附质。吹扫气体在新再生的床上清洗并循环使用。溶质运动理论（局部平衡分析）和数值解将用于预测再生。吸附剂的再生是一个能源密集型的步骤，控制着商业系统的成本。拟议的技术应显著减少能源需求，提高再生率和提高工艺效率。这将对各种气体吸附和分离技术产生影响。

Abstract Proposal No: 9710553 Proposal Type: Investigator Initiated Principal Investigator: Philip C. Wankat Affiliation: Purdue University This grant is awarded through the Separations and Purification Program sub-element of the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The principal investigator is Dr. Philip C. Wankat at Purdue University. The research will evaluate a new method for the regeneration of adsorption columns. The method uses hot pure adsorbate vapor to heat the column. The latent heat available in the vapor is used to heat the column when the adsorbate vapor condenses on the adsorbent. A cold inert purge gas is used to purge the adsorbate out of the hot bed. Unlike normal steam regeneration, the heating and purge steps are decoupled. Pure adsorbate is recovered from the purge gas by condensation. The purge gas is cleaned in a newly regenerated bed and recycled. Solute movement theory (local equilibrium analysis) and numerical solution will be used to predict regeneration. Regeneration of adsorbents is an energy intensive step that controls the cost of commercial systems. The proposed technology should significantly reduce energy requirements, improve regeneration rates and enhance process efficiency. This would have an impact on various gas adsorption and separation technologies.
