In 10 animals (4 controls and 6 hydroxocobalamin-treated rats), a 7 ml mixing chamber was connected to the expiratory port of the valve, where mixed expiratory gas composition was continuously sampled and analyzed (GEMINI, CWE Inc., Ardmore, PA, USA).
During the initial 3 min of each exercise stage, the 2100 stopcock was used to periodically alternate gas into each system to ensure each mixing chamber had similar mixed expired gas compositions.
The gas composition of mixed fuel which consists of 50% biomass and 50% coal was compared with the syngas composition of rice husk and bagasse.
In mixed gas permeation experiments, when the composition of the feed gas was 98 mol% CH4 and 2 mol% n-C4H10, uncrosslinked PTMSP had an n-C4H10/CH4 n-C4H10/CH4 of 31 and an n-C4H10 permeability of 114,000 barrerselectivityand 14 atm feed fugacity.
13C cross-polarization (CP) NMR spectra of the mixed hydrates at gas compositions of more than 10 mol% CO2 with the balance N2 identified that the crystal structure of mixed hydrates as structure I, and that the CO2 molecules occupy mainly the abundant 51262 cages.
This technique provides rapid measurement (∼ 2s) of gas composition in a well-mixed flow reactor so that reaction rates could be examined quantitatively.
Based on spatial and temporal distribution of mixed gas displacement, displacement efficiency is controlled by the composition and competitive sorption of the mixture.
In addition, dynamic column breakthrough experiments were performed using a binary CO2/N2 mixed gas with a molar ratio of 15:85 to mimic the flue gas composition.
To demonstrate the Gradient Assisted Robust Optimization technique capabilities, we developed a refrigerant mixture for propane precooled mixed refrigerant natural gas liquefaction cycles with an exaggerated variation in feed gas composition.
