Sodium lignosulfonate is a polymer with extensive sources and abundant functional groups. Therefore, it has potential value for research wide utilization. In this study, the adsorption material was prepared by blending sodium chitosan, which could adsorb anionic cationic dyes metal ions. The composite characterized Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetry (TG). results showed that cross-linked mainly strong electrostatic...
Abstract Most past studies on coal shrinkage/swelling due to gas adsorption/ desorption were based experiments under no constraint conditions. In this paper, the changes of stress and strain measured one specimen uniaxial compression in a vacuum axial conditions during CO2 adsorption are presented numerically simulated. The simulation results show that linear elastic deformation model, suitable isotropic continuum media but widely assumed analytical permeability models, cannot adequately...
Nb 2 O 5 can adjust the electronic structure of SNiC 4 and improve catalytic activity. Replacing OER with HzOR for hydrogen production save 80% energy consumption.
Efficient electrocatalysts require not only a tunable electronic structure but also great active site accessibility and favorable mass transfer. Here, two-dimensional/three-dimensional (2D/3D) hierarchical electrocatalyst consisting of Co(OH)2-CeO2 nanosheet-decorated Co dendrites is proposed, named as Co(OH)2-CeO2/Co. Based on the strong interaction heterojunction, optimized, which facilitates adsorption intermediates dissociation H2O. Moreover, open 2D/3D formed by introducing substrate...
Electrochemical water splitting is widely studied in the hope of solving environmental deterioration and energy shortage. The design inexpensive metal catalysts exhibiting desired catalytic performance durable stability for efficient oxygen evolution pursuit sustainable clean fields. Herein, a three-dimensional (3D) flower-like NiSe2 primary structure, modified with highly dispersed CuSe2 nanoclusters as secondary obtained by regulating growth trend nanosheets. Benefiting from metallicity...
Abstract An overview of coalbed methane (CBM) reservoir characteristics, its unique production mechanisms, and the influence geomechanical processes on these mechanisms are discussed from a engineering point view. Models have been developed to predict changes in cleat porosity permeability with situ conditions (stress, pressure, gas sorption, temperature). Explicit-sequential coupling simulations conducted for conventional CBM depletion production. The study shows that during production,...
Abstract Permeability of coal seams is one the key factors for success coalbed methane (CBM) developments. It dominated by cleat permeability in coal, which very sensitive to change effective stresses. The matrix shrinkage due production also influences permeability. Using an explicit-coupling simulation method, simultaneously simulates multiphase fluid flow and deformation, a coupling model, considers effects stress on permeability, sensitivity CBM ten engineering, geologic, intrinsic...
In this work, the low-temperature oxidation (LTO) characteristics of different API gravity crude oils, involving one light, medium, and heavy, are studied comprehensively from aspects effluent gas, oxidized oil, pressure drop. The results reveal that heavy oil exhibits faster LTO reaction rate stronger O2 consumption capability compared with lighter ones. There a certain amount carbonaceous deposits in oils carbonation progress is brought to deeper degree. drop rule samples speculated be...
An eco-friendly and novel water treatment material was synthesized using sodium lignosulfonate modified polystyrene (SLPS), which can be used to eliminate phenols in aqueous solution. SLPS characterized by BET, FTIR, SEM, EDS. The effect of the initial pH value, phenol content, adsorption time, temperature on absorbability investigated through experiments. It found that could efficiently adsorb solution at a value about 7. test results revealed kinetic isotherm successfully described pseudo...
Abstract A sugar amine sulfonate surfactant (SAS) was used to enhance oil recovery by chemical flooding. The interfacial tension between an SAS solution and four kinds of crude determined. Oil (4) containing the largest amount medium chain length components most suitable candidate because IFT could be reduced ultralow range (10 −3 mN/m) at optimum NaCl concentration. Emulsions consisting adsorption density on sandstone were studied. Compared with A37 (alkyl ether sulfate), ws able form more...
In this work, the effects of oxygen concentration and reservoir cutting on thermokinetic characteristics light oil were analyzed using thermogravimetry (TG/DTG). Results show that three consecutive oxidation reactions distinct chemical mechanism (low-temperature [LTO], fuel deposition [FD], high-temperature oxidation) are detected for all tested samples. Hypoxic air weakens LTO FD process causes a poor performance, while positively influences thermal oil. Kinetic parameters comparison...
