Adsorbents and fixed-bed reactors are ubiquitous throughout industry. The optimal design of these beds can lead to more efficient and economical reaction processes. However, the development of new adsorption systems has intricacies that need to be accounted for during research and development, such as the effects of particle size and packing on fluid flow.
In the AIChE Journal article, “Capturing the Effects of Particle Heterogeneity on Adsorption in a Fixed Bed,” Jillian Goldfarb (Cornell Univ.) and co-authors explore the importance of understanding and accounting for the effects of local heterogeneities in the design of adsorbent beds, especially when working on early-stage, small-scale lab experiments.
Adsorbents are used across industrial sectors to dry and purify air, separate gas streams, sequester water pollutants, manage spills, support heterogeneous catalysis, decolorize food products, and recover byproducts during petrochemical refining, among other applications. During adsorption, one substance, the adsorbate, is separated from one phase and sequestered on the surface of a second phase, known as the...
