“…The desorbent enters from the end of zone III, and the binary mixture is fed between zones I and II. Finally, the heavy fraction (extract) exits between zones II and III, and the light fraction (raffinate) exits from the front end of zone I [38][39][40][41].…”

Simulated moving bed (SMB) chromatography is a highly efficient adsorption-based separation technology with various industrial applications. At present, its application has been successfully extended to the biochemical and pharmaceutical industrial sectors. SMB possesses the advantages of high product purity and yield, large feed treatment capacity, and simple process control due to the continuous operation mode and the efficient separation mechanism, particularly for difficult separation. Moreover, SMB performs well, particularly for multi-component separation or complicated systems’ purification processes in which each component exhibits similar properties and low resolution. With the development of the economy and technology, SMB technology needs to be improved and optimized to enhance its performance and deal with more complex separation tasks. This paper summarizes the typical variants or modifications of the SMB process through three aspects: zone variant, gradient variant, and feed or operation variant. The corresponding modification principles, operating modes, advantages, limitations, and practical application areas of each variant were comprehensively investigated. Finally, the application prospect and development direction were summarized, which could provide valuable recommendations and guidance for future research in the SMB area.

“…Physisorbents such as metal–organic materials (MOMs), − especially flexible MOMs (FMOMs), − have exhibited promising characteristics for C8 separation. ,− Notably, two-dimensional (2D) layered coordination networks, , one-dimensional (1D) chain coordination polymers, , and zero-dimensional (0D) coordination complexes − can offer selective binding of C8 guests through C8-induced structural phase transformations from guest-free apohosts (α-phases) to inclusion compounds (β-phases) . Organic molecular solids can also undergo phase transformations induced by guest molecules − and offer selective binding of C8 isomers. ,,− In terms of selectivity, a cage host with intrinsic porosity was found to offer across-the-board PX selectivity ranging between 6.60 and 12.10 .…”
