The sorption-induced porosity and permeability alteration of coal beds as pore pressure and in-situ stress are varied can be couched within the frameworks of ‘open thermodynamic system' and ‘open-system geomechanics' (OSG). Production from coal bed methane (CBM) reservoir changes not only the fluid mass (gas and water) but also solid mass as a result of methane desorption from rock matrix. The ...

Due to their hygroscopic characteristics, equilibrium moisture contents of agricultural products and byproducts are important factors quality. Defatted cottonseed meal (CSM), washed (WCSM) protein isolate (CSPI) can be used as energy sources animal feedstuff or industrial raw materials. Information on adsorption behaviors is needed for storage conditions quality control. Thus, this work measure...

Sorption enhanced synthesis has been previously shown to improve carbon dioxide hydrogenation methanol by mitigating the thermodynamic limitations. This work investigates efficiency of via sorption focusing on determining optimal process parameters. The study is based upon a fully dynamic experimentally validated model which extended account for adsorbent regeneration, downstream product separa...

Understanding how sorption depends on temperature a molecular basis has been made difficult by the coexistence of isotherm models, each assuming different mechanism and routine application planar, multilayer models (such as Brunauer–Emmett–Teller (BET) Guggenheim–Anderson–de Boer (GAB)) beyond their premises. Furthermore, common observation that adsorption isotherms measured at temperatures fal...

The adsorption properties of Shanghai silty clay (SSC) towards heavy metal ions Cd(II), Pb(II), As(V), and Cr(VI) were investigated by batch experiments. effects solid-solution ratio, pH, temperature, reaction time, concentration on sorption analyzed. In order to better understand the mechanisms, X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence (XRF) used analyze soil s...
