The biofiltration and the biologic expanded bed techniques were adopted in succession to treat ammonia-contaminated gas streams, then the advantage and disadvantage of the two techniques were compared in detail, to overcome the shortage of the two techniques, a novel biological process for the treatment odors was established ,which was the result of the bi.

Study on characterization and test of presulfiding of hydrogenation catalyst in expanded bed;

Purification of nattokinase by ion exchange adsorption in expanded bed;

Hydrodynamic modeling in expanded beds for protein purification;

The expansion of biological fluidized bed has a strong relationship with hydraulic dynamics and efficiency in biochemical reaction zone, bed expansion characteristics are fundamentally important for us to design and run liquid solid biological fluidized bed.

It focuses on reviewing the effect of temperature on the minimum fluidization velocity, minimum fluidization voidage, bed expansion ratio, and bubble diameter, which are in relation with the design and operation of fluidized beds.

Particle circulation technique between the two beds and fluidized bed expansion characteristics.

Research on slight expanded-bed oil residue hydrotreating reactor;
