Temperature changes in CO2 foam-fracturing construction can easily affect surfactant foam stability. To investigate the effect of temperature on stability different types surfactants, this study measured half-life and viscosity four typical CTAB, LAS-30, HSB1214, TX-10, using a novel self-designed built performance measurement device. The effects were studied. results show that as increased, shortened, liquid phase decreased, which led to decrease Moreover, Materials Studio, type molecular...
The occurrence of metal ions in the form inorganic minerals coal is one main factors that affect stability surfactant foams. To explore effect seams on anionic sodium dodecyl sulfate (SDS) foam, changes half-life SDS foam under different base fluids were analyzed. results showed promoted foam. When Na+ concentration fluid increased from 20 to 40 mg/L, by 67 s. Mg2+ 5 15 148 influence divalent was more pronounced than monovalent Na+. A two-phase molecular dynamics model at interface...
The threshold dilution ratio of acetaldehyde is much larger than those other odor compounds generated during the spontaneous combustion process and so it most important odorant. Studying mechanism by which can provide necessary theoretical support for acetaldehyde-based analysis. In present work, release was monitored while heating lignite, long-flame coal, coking coal specimens under either air or nitrogen. data show that primarily produced oxidation active sites in rather pyrolysis...
A FeMnCe-activated semi-coke catalyst (FeMnCe/ASC) was prepared by the co-precipitation method using as raw material. The structure and morphology were characterized X-ray diffraction, Brunauer-Emmett-Teller, scanning electron microscopy, transmission microscopy analyses. catalytic activity stability of FeMnCe/ASC investigated with piperazine target degradation pollutant ammonia nitrogen chemical oxygen demand (COD) evaluation indexes. results showed that average pore size mesopores 6.68 nm,...
Coal plays a crucial role in the energy structure of China. However, coal oxidation goaf areas can lead to spontaneous combustion and release harmful substances, such as CO2 As2O3, which pose environmental hazards. The transport patterns As2O3 from mining area surface were investigated, impacts their preliminarily investigated. This study aimed obtain data on relationship between during temperature, serving baseline information for numerical models combustion. From macro perspective, we...
The adsorption of dodecyl trimethyl ammonium bromide (DTAB) on coal can affect the wettability and change water absorption coal. After DTAB treatment, in CH4 capacity is worth further study. To reveal microscopic mechanism influence coal, we employed density functional theory (DFT) with 6-311 G (d, p) basis set. DFT-based computations interpreted process molecules determined stable structure, distance, Mulliken overlapping populations, energies two configurations. results showed that...
