The adsorption/desorption characteristics of a coal reservoir play an important role in coalbed methane (CBM) development. proximate analysis, maceral analysis and isothermal experiment are carried out based on samples from no. 4+5 seam Baode block. Combing with experimental data the CBM well-produced water salinity block, effect content its influencing mechanism is discussed. results show that...

Adsorbed gas is an important component of shale gas. The methane adsorption capacity determines the composition In this study, marine, transitional, and lacustrine shales in Sichuan Basin was analyzed through its isothermal adsorption, mineral composition, water content, etc. results show that marine (Qiongzhusi Formation Longmaxi Formation), transitional (Longtan (Xujiahe Ziliujing Formation) ...

The addition of corrosion inhibitors into the acidic environment is an environmental modification to control rate corrosion. Organic compound become environmentally friendly alternative. In this study, research and analysis have been carried out on jackfruit peel extract as a inhibitor for AISI 1037 carbon steel protection in 1M HCl solution. Variation concentration 200-3000 ppm. Corrosion meas...

The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of amylase and protease on to manganese ferrite (MnFe2O4). The metal ferrite was synthesized via a sol – gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnet...

The uses of MCM-41 as adsorbent have been studied as an alternative substitution of activated carbon for theremoval dyes. This adsorbent was prepared at laboratory by authors. Adsorption of safranine on MCM-41was studied to examine adsorption thermodynamics. In this study was investigated the effect of proccesparameters like pH, initial dye concentration, temperature and adsorbent mass. MCM-41,...

absorptive characteristics of polyaniline synthesized with two different oxidants including potassium iodate and ammonium persulfate was studied. synthesized polyanilines in powder shape is used as an adsorbent to remove toxic hexavalent chromium from aqueous solutions. experiments were conducted in batch mode with different variables such as agitation time, solution ph and initial concentratio...

land treatment method of municipal and industrial wastewaters for utilization of nutrients in the wastes for raising useful crops and tertiary(or advanced) treatment of the water for improving stream quality or to recharge falling water tables is increasing in some parts of the world, particulary in the arid area. as emphasis in this type of treatment method and prevention of surface and underg...

Abstract This study evaluated the characteristics and mechanism of phosphate adsorption by fly ash discharged from a biomass thermal power plant (BTP-FA) under various environmental conditions in order to increase recyclability BTP-FA. The properties BTP-FA derived coal (CTP-FA) were better matched those predicted Langmuir isothermal model pseudo-second-order model, their maximum capacities 62....
