The present disclosure provides a method of separating α-olefin by a simulated moving bed. The method comprises using a coal-based Fischer-Tropsch synthetic oil as a raw material to obtain a target olefin having a carbon number N within a range from 9 to 18, wherein the raw material is subjected to treatment steps including pretreatment, fraction cutting, alkane-alkene separation, and isomer separation, thereby obtaining a high purity α-olefin product. As compared to conventional rectification and extraction processes, the product obtained by the method of the present disclosure has advantages of higher purity, higher yield, lower energy consumption, and significantly reduced production cost.

The present invention relates to new methods for the purification of immunoglobulins from cell culture harvest. These methods are characterized by cleaning steps preceding an initial capture chromatography step. Preferably, the initial capture chromatography is an affinity chromatography and the pre-capture cleaning effect is obtained by flocculation and filtration. By using such pre-capture cleaning steps, an improved quality of the eluted immunoglobulin from the capture matrix is achieved. Furthermore, the enhanced clarification of the cell culture liquid results in reduced precipitations during affinity chromatography and thus increases the lifetimes of the expensive affinity resin. This is an important improvement for immunoglobulin purification in large scale production. The present invention further relates to sequential polishing chromatographies and filtration steps downstream to the capture chromatography, yielding immunoglobulins of high purity.

This invention relates generally to a process for selective adsorption and recovery of lithium from natural and synthetic brines, and more particular to a process for recovering lithium from a natural or synthetic brine solution by passing the brine solution through a lithium selective adsorbent in a continuous countercurrent adsorption and desorption circuit.
