Modeling of coal swelling induced by water vapor adsorption

Zhejun PAN

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1,   Pages 94-103 doi: 10.1007/s11705-011-1172-2

Abstract: Gas adsorption-induced coal swelling is a well-know phenomenon.Coal swelling or shrinkage by adsorption or desorption of water vapor has not been well understood butIn this work, a model has been developed to describe the coal swelling strain with respect to the amountThe model extended an energy balance approach for gas adsorption-induced coal swelling to water vaporThe model is applied to describe the experimental swelling strain data measured on an Australian coal

Preparation and swelling properties of a starch-g-poly(acrylic acid)/organo-mordenite hydrogel composite

Yan Zhang,Pingqiang Gao,Lin Zhao,Yizhong Chen

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 1,   Pages 147-161 doi: 10.1007/s11705-015-1546-y

Abstract: The swelling capacity of the hydrogel composite was evaluated in distilled water, and solutions withincorporation of 10 wt-% organo-mordenite enhanced the water absorbency by 144% (from 268 to 655 g·g ) and swellingSwelling kinetics and water diffusion mechanism of the hydrogel composite in distilled water were alsocycles and the hydrogel composite exhibited significant environmental-responsiveness by changing the swelling

on the mixed sand ratio and initial dry density of weathered sand improved expansive soil free load swelling

Yang Jun,Yang Zhi,Zhang Guodong,Tang Yunwei and Chen Hongping

Strategic Study of CAE 2014, Volume 16, Issue 2,   Pages 73-78

Abstract:

Through the indoor free load swelling rate test，Yichang City，a section of a highway reconstructionKey analysis free load swelling rate of a non-load time，the proportion of mixed sand，the relationshipbetween the initial dry density， experimental studies have shown that：Free load swelling rate is mainlystabilize in three stages；during the initial dry density is constant，weathered sand soil free load swellingnot sensitive to the amount of sand mixed；in the same mixed sand ratio， weathered sand soil free load swelling
