Storage of natural gas by adsorption or called Adsorbed Natural Gas (ANG) has the potential to replace Compressed Natural Gas (CNG) in mobile storage applications, such as in vehicles. ANG storage at moderate pressure around 3.5 to 4.2 MPa could be expected to reduce the problem of bulky storage within a confined space of high-pressure CNG storage used in vehicle. In adsorptive storage, the amo...

Grand canonical Monte Carlo (GCMC) simulation was used for the systematic investigation of the supercritical methane adsorption at 273 K on an open graphite surface and in slit-like micropores of different sizes. For both considered adsorption systems the calculated excess adsorption isotherms exhibit a maximum. The effect of the pore size on the maximum surface excess and isosteric enthalpy of...

Petroleum and dairy operations are prominent sources of gas-phase organic compounds in California’s San Joaquin Valley. It is essential to understand the emissions and air quality impacts of these relatively understudied sources, especially for oil/gas operations in light of increasing US production. Ground site measurements in Bakersfield and regional aircraft measurements of reactive gas-phas...

A special organic ligand, 4-carboxypyrazole (4-cpz), is chosen to synthesize a highly stable metal-organic framework (MOF) for selective sorption of light hydrocarbons. The new MOF, (H(3)O)[Zn(3)(OH)(4-cpz)3]·2(DEF)·H(2)O (FIR-51, DEF = N,N-diethylformamide), was synthesized solvothermally and shows unusual chemical stability. This compound exhibits high storage capacity for light hydrocarbons ...
