Sentence examples for biogas composition from inspiring English sources

Biogas composition was determined using a gas chromatograph (Clarus 580, Perkin Elmer) equipped with a thermal conductivity detector.

Biogas composition was 71±2%2% methane and 26 ± 4% carbon dioxide.

Based on the experimental results, the numerical model was validated and calibrated under various excess air ratio (EAR), boost pressure, spark timing, and biogas composition conditions.

The OLR (organic loading rate) in the UASB reactor highly correlated with the specific biogas production rate (p < 0.01), although biogas composition differed significantly among the three periods.

Appropriate boost pressures to produce the same brake power at a given relative air/fuel ratio of 1.1 without boost were determined for each relative air/fuel ratio or each biogas composition considering brake power.

The study was conducted on a 4-cylinder, 1.9L Volkswagen TDI Diesel engine, which was modified to run in HCCI mode with biogas by means of inlet charge temperature control, boosted intake pressure, and a sonic flow device upstream of the inlet manifold to control biogas composition and the equivalence ratio.

A wide range of biogas compositions differing in CH4 content was simulated.

Optimum boost pressures were optimized for various biogas compositions and relative AF ratios through maximum brake torque timing (MBT) optimization.

The effect of methane CO2 blends with varying CO2 concentrations (corresponding to various biogas compositions) on combustion and emission characteristics were investigated numerically for a gas engine generator.

In general, the lean operation limit was extended up to a relative air/fuel ratio of 1.5 with various biogas compositions and up to a relative air/fuel ratio of 1.7 for CH4 CO2 volume ratios of 65%35%and70%30%:30% without knocking.

Although natural gas and biogas compositions are different at all sites, a slight biogas performance advantage over natural gas is clearly evident at each site.
