The development of adsorbent for normal paraffin adsorption-separation in these decades is discussed in this paper.

Through the technical renovation in heap leaching such as establishing the regular and permanent heap yard, reducing the ore grain size and utiliaing the now type carbon adsorption technology, the technical indexes of heap leaching are significantly promoted and the heap leaching recovery is upgraded from 75.

Simulated moving bed adsorption separation technology and its applications;

Adsorption separation process for intermediate component preparation and its application;

A coupled pretreatment technique, ultrasonic and adsorption separation, was investigated for pesticide residues in tea prior to gas chromatography determination.

A dynamic mixing cell model is developed based on analyzing the SMB ( simulated moving bed) adsorption industrial process for separation of C_8 aromatics.

992 mmol(g-1, and the equilibrium adsorption ratio for C2H4/C2H6 is 3.

The effects of the NaOH concentration, adsorptive temperature,adsorptive time, amount of adsorbent on the adsorption capacity were investigated respectivelyExperimental results showed that the new adsorbent was efficient in NaCl adsorption in highconcentration NaoH solution, and can be regenerated easily The adsorbent displayed goodadsorptive performance after it was used more than ten times.

Producing dichloromethane and trichloromethane by combined adsorptive separation technology of heat-chlorinating methane;

The application study of mesopore-enriched bamboo activated carbon in methane adsorptive separation and storage;

Recent progress of separation of xylene isomers and ethylbenzene from C_8 aromatic hydrocarbon is expounded with emphasis on technical features of adsorptive separation technologies and their industrial applications.
