Influence of Hydrate-Forming Gas Pressure on Equilibrium Pore Water Content in Soils

open access: yesEnergies, 2021
Natural gas hydrates (primarily methane hydrates) are considered to be an important and promising unconventional source of hydrocarbons. Most natural gas hydrate accumulations exist in pore space and are associated with reservoir rocks.

Fischer-tropsch synthesis on iron-based catalysts: the effect of co-feeding small oxygenates [PDF]

open access: yes, 1989
Co-feeding experiments have shown that ethers can participate substantially in the Fischer-Tropsch synthesis with iron catalysts. Dimethyl ether is thought to be capable of building up surface complexes which are very similar to those naturally occurring
