The virial expansion for non-spherical Kihara molecules is applied to determine the critical constants of n-alkanes (methane to octane) and cyclic hydrocarbons (cyclopentane, cyclohexane, benzene and naphthalene); a fair agreement with experimental data was found....
The theory correctly predicts the existence of a maximum in the critical density of n-alkanes. When differences in the energetic interactions between methane, methyl and methylene groups are included, a maximum in the critical pressure is found for ethane, in good agreement with experiment. The ...

The highest methane yield after pretreatment was 466.01 ± 10.85 mL/g VS in the reactor, where the sulphuric acid pretreatment concentration was 3.0% v/v. Control of acid pretreatment results were achieved by analysis of lignocellulosic degradation and increase in soluble chemical oxygen demand. The...
Thermocatalytic decomposition of methane has been one of the most economical hydrogen production methods. Electrocatalysis is used to facilitate the charge transfer between electrode and reactant in electrochemical reactions28. Electrochemical therapy (EChT) has been used clinically for cancer therapy by ...

If we are to predict the properties of heavy liquids with corresponding-states correlations based on critical constants, we will need to extrapolate available data for lighter liquids to higher carbon numbers. Such extrapolations are possible, at least empirically, because critical constants apparently...

However, most company and government pledges focus on the year that net zero is reached, with limited awareness of how critical the emissions pathway is in determining the climate outcome in both the near- and long-term. Here we show that different pathways of carbon dioxide and methane—the ...
