In spite of its importance, it is got less attention due to complex experimental procedures and low range of temperature and pressure applicability in the experimental conditions. To shed light on the effects of the impurity on the diffusion coefficient of CO2锕歛ter systems, two types of ...

The CO2-effective diffusion coefficient is a key parameter in the modelling of carbonation of cementitious materials. It is usually deduced from empirical relationships determined by tests on mixtures made with Ordinary Portland Cement (OPC). These relationships are a priori non-valid for materials ...
For CO2, the interaction energies (CO2–CO2 and CO2–CNT) are larger than that of CH4 in all cases. But only a very small difference in the diffusion coefficient was observed between CO2 and CH4. Temperature has a negligible effect on the difference between diffusion coefficients of CO2 and ...
Inference latency of the developed model has been established. Abstract Optimizing CO2injection for enhanced oil recovery (EOR) requires a precise estimation of the CO2-diffusivity coefficient in porous media. This study developed a predictive model for the molecular diffusivity coefficient of CO2in bitu...
Measurement and modeling of CO2 diffusion coefficient in Saline Aquifer at reservoir conditions Storage of CO2 in deep saline aquifers is a promising techniques to mitigate global warming and reduce greenhouse gases (GHG). Correct measurement of diffu... R Azin,M Mahmoudy,SMJ Raad,... - 《Centr...
Na doping of middle rank coal enhances its carbon capture capacity.The binding energy required for doping is proportional to the atomic radius.The highest adsorption for CO2(5.934mmol/g) was found in the Na-CYM system.The diffusion coefficient of CO2is minimized in the Li-coal system.关键词:...
and where the notation [η]iindicates theith order approximation of the transport property η and E∗ is defined below. Higher order approximations differ from first order by 1–2%. Calculation of the diffusion coefficient requires the collision integral having l,s= 1, and thermal conductivity ...
Photon correlation spectroscopy (PCS) was used to measure the binary diffusion coefficient and viscosity in the CO2-n-heptane system in the two-phase region. The measurements covered a temperature range of 10-50°C and a pressure range of 1-8 MPa. At constant temperature, DAB went through a...
Determination of the interparticular effective diffusion coefficient for CO2 and O2 in solid state fermentation A simple experimental diffusion controlled fermentor (DCF), coupled with the use of a mathematical model based on mass balance, is proposed to measure the ... R Auria,J Palacios,S Revah...
