An uncommon nickel dinitrogen adduct and its tendency toward CO2 binding are investigated using a (PP(Me)P)Ni scaffold. (PP(Me)P)Ni(N2) (1) and {(PP(Me)P)Ni}2(μ-N2) (2) were prepared and their treatment with CO2 revealed the formation of (PP(Me)P)Ni(η(2)-CO2) (3). This is a new type of CO2 binding for a zero-valent nickel center supported by three donor ligands, reminiscent of the CODH active s...

The effect of varying the CO-CO2 and CO2-N2 ratios was investigated in the presence of coal in a specially designed 3-electrode setup, used to simulate the anode compartment in a hybrid direct carbon fuel cell (HDCFC). The HDCFC consists of a hybrid between a molten carbonate and a solid oxide fuel cell (SOFC). It was shown that the cell performance improved with increased CO2 content in the CO...

Greenhouse gas CO2 emissions to the atmosphere are believed to be the primary reason for the global warming. One effective way to mitigate CO2 emissions is to capture CO2 from post-combustion flue gas in coal-fired power plants. Membrane technology has been widely explored for this application due to its high energy-efficiency. Current membrane materials are often based on poly(ethylene oxide) ...

MIL-101(Cr) has drawn much attention due to its high stability compared with other metal-organic frameworks. In this study, three trace flue gas contaminants (H2O, NO, SO2) were each added to a 10 vol% CO2/N2 feed flow and found to have a minimal impact on the adsorption capacity of CO2. In dynamic CO2 regeneration experiments, complete regeneration occurred in 10 min at 328 K for temperature s...

The Oil & Gas Journal, in 2004, states that CO2 flooding is the fastest-growing enhanced oil recovery technique in USA, and production derived from CO2 projects has more than tripled from 50,000-Barrels/day to 200,000-Barrels/day. Cyclic injection of CO2 and N2 combines environmental benefits attendant to reducing CO2 concentrations in the atmosphere and economic benefits realized through impro...

The effects of different modified atmospheres (air: atm1; 100% CO2: atm2; 100% N2: atm3; 50% CO2/50% N2: atm4) on the textural and sensory characteristics of the ready-to-serve pizza at 7 ̊C ± 1 ̊C were investigated. The values of hardness, gumminess and chewiness were found to be increased during the storage period while cohesiveness and springiness exhibited a decreasing trend. Overall, the 100...

Different alkylamine molecules were post-synthetically tethered to the unsaturated Cr(III) centers in the metal-organic framework MIL-101. The resultant metal-organic frameworks show almost no N2 adsorption with significantly enhanced CO2 capture under ambient conditions as a result of the interaction between amine groups and CO2 molecules. Given the extraordinary stability, high CO2 uptake, ul...

Gas clusters can reprove the sewage ability of flame-permeability char joint, but interaction motion between proposed vapor molecules and gasoline-confine charcoal during wind enema advance is still unclear. For this consideration, supported by surface assimilation figure qualifier-enclose char, magnificent orthodox whole Monte Carlo (GCMC) manner was interesting to ponder elution conduct CH4 i...

An open-cage C60 tetraketone with a large opening was able to encapsulate N2 and CO2 molecules after its exposure to high pressures of N2 and CO2 gas. A subsequent selective reduction of one of the four carbonyl groups on the rim of the opening induced a contraction of the opening (→2) and trapped the guest molecules inside 2. The thus-obtained host-guest complexes N2@2 and CO2@2 could be isola...
