Adsorption Behaviour of Normal Paraffins in a Fixed Bed Adsorber Containing 5 Å Molecular Sieves

Progress in heteroatom - containing aluminophosphate molecular sieves

Over the past 30 years, heteroatom-containing aluminophosphate molecular sieves as a prime class of heterogeneous single-site solid catalysts have been quickly developed since the first discovery of aluminophosphate molecular sieves in 1982, and a large variety of such materials with 48 unique zeotype structures have been prepared. This work mainly presents the progress in the development of he...

Carbon Molecular Sieves for Hydrocarbon Separations by Adsorption

Continuous Desalting of Proteins with a Simulated Moving-bed Adsorber

A simulated moving-bed adsorber (SMBA)consisting of only three or four columns packed with gel chromatographic materials was applied for the continuous desalting of bovine serum albumin (BSA) from ammoniumsulfate. It was shownexperimentally that the solutes could be continuously recovered in different streams at concentrations of over 50% of their feed concentrations. The recovery of BSAwas in ...

Comments on the behaviour of a fixed-bed reactor

Dear Sirs, In a recent series co-workers (see e.g. of papers by Morbidelli and Varma and Morbidelli and Varma 1986a; Morbidelli et al., 1986h Lee and Varma, 1987, 1988; Bauman and Varma 1990), the multiplicity behaviour of a fixed bed reactor is discussed. The basis for this analysis was given by Morbidelli and Varma (1986a) and Morbid& et al. (1986b), where the authors devote many columns to m...

Molecular simulations of the adsorption and diffusion of hydrocarbons in molecular sieves

In this short review it is demonstrated how molecular simulation can be used to obtain molecular insights in the behaviour of molecules inside the pores of zeolites. Whereas straightforward molecular dynamics can be used to study the behaviour of small molecules inside the pores, the study of the long chain hydrocarbons that are important in petrochemical applications require special computatio...
