The higher the SiO2/Al2O3 ratio of the MCM-22(P),the lower the charge density on the sheet surface,the weaker the electrostatic attractive force and the intermolecular force between the interlayer cation and negatively charged sheets,which made the intercalation swelling and succedent ultrasonic exfoliation easier.

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.

K+ and pllyvinyl alcohol were choosen as the inhibition reagent on the hydrating and swelling behavior of expansive soil on the basis of the studies on crystalline swelling and osmosis swelling.

Local phase holdups and bed expansion ratio(H/H0) near gas distributor region were investigated.
