For air⁃water⁃air⁃water⁃water⁃anion exchange resin system, the effects of solid loading, particle size, separator and different guide tube forms on mass transfer coefficients were studied in an airlift cyclone reactor (HALR) with a volume of 130 L (inner diameter 290 mm and height 2 000 mm) and an apparent gas velocity of 0~0.84 cm/s. The results showed that the volumetric mass transfer coefficients of the three phases system were larger than the two phases. As the particle size increased, the volumetric mass transfer coefficients decreased. The volumetric mass transfer coefficients with the solid separator was a little bigger than the none of separator.The volumetric mass transfer coefficient of the finned draft tube was the largest when the superficial gas velocity was small.

Influence of ASP system on the fracture conductivity of alkaliresistance resin sands and quartz sands was studied. The results showed that compared with the weak base, the dissolution of strong base on the quartz sands was more serious. And the damage percentage of the particles was higher. Therefore the reduction of conductivity of fractures packed with sands was larger. Compared with quartz sands, there was little difference between the dissolution of weak base on the alkaliresistance resin sands and that of weak base on the alkaliresistance resin sands. So it was the same to conductivity. With the increase of closing pressure, the conductivity of quartz sands and alkaliresistance resin sands were both weakened. But the reduction degree became gradually small. Compared with quartz sands, the influence of closing pressure on the conductivity of fractures packed with alkaliresistance resin sands was weak. And the fracture conductivity capacity was stronger.
