Shales of western Guizhou in China were collected from wells and subjected to experiments under formation conditions (e.g. thermal simulation, Rock-Eval pyrolysis, X-ray diffraction and CH 4 isotherm adsorption). A thermogenic gas generation model was established based on the logistic model, a ...
A new numerical procedure, based on the simulated annealing algorithm (SA), for optimizing the parameters of a new recently developed gamma-type adsorption isotherm equation is proposed. This procedure is verified for three modeled adsorption isotherms assuming some arbitrarily chosen shapes of the pore...

S2, the adsorption-desorption isotherms of all the samples exhibit the IV isotherm with the H3-type hysteresis loop and the insets show the pore size distribution of all the samples. According to the IUPAC definition, it is a typical mesoporous structure, which may be due to the stacking ...
whereQº is the amount of adsorbate at complete monolayer coverage (mg g−1), from which the maximum sorption capacity of the sorbent can be derived, andb(L mg−1) is the Langmuir isotherm constant, which is related to the energy of adsorption24. The Langmuir isotherms for1-EIR are...
A parameter c which is closely related to the constant c of a BET isotherm is found to characterize the distinctness of the layered structure of an adsorbed phase. Excluding the last two types, the empirical BDDT classification of adsorption isotherms is explained in terms of the distinctness of...

The structure and textural parameters of samples obtained were also characterized by low temperature N 2 adsorption/ desorption measurements. The isotherms obtained are pre- sented in Fig. 3. The support material shows a typical shape of N2 adsorption/desorption isotherm for SBA-15 ...
aFollowing the classification of IUPAC, all the nitrogen adsorption–desorption isotherms are considered to be a typical type IV isotherm, which suggests that raw diatomite and ferrihydrite-modified diatomite are a mesoporous material. 在IUPAC的分类以后,所有氮气吸附解吸附作用等温线认为一个典型的类型IV等...
aThe explicit isotherm of L-shape, according to Giles et al.[28],indicated that there is no strong competition between the solvent and the dye to occupy the CTNTs active sites.Moreover,this type of isotherm implies Langmuir-type adsorption between MB and CTNTs molecules. L形状明确等温线,根据...
