What are the characteristics of methane gas
Physical and chemical properties of BiogasMethane is a colorless, smell, toxic, foul gas, which is the main component of methane at room temperature is a colorless, tasteless, non-toxic, no smell of gas. The methane molecule is CH4, is simple hydrocarbons with a carbon atom and four hydrogen atoms. The weight of methane the air is more than 0.54, about half the lighter than air. Methane Solubility rarely, at 20 C, 100 kPa, 100 per unit volume of water, only 3 per unit volume of methane dissolved.
Methane is simple organic compounds, is the quality of the fuel gas when burning blue flame, the maximum temperature of 1400 degrees Celsius. Pure methane per cubic meter of heat for 36 thousand and 800 heating coke. The amount of methane per cubic meter about 23 thousand and 400 coke, equivalent to 0.55 kg or 0.8 kg of coal combustion diesel after the heat released from the analysis. The thermal efficiency of biogas per cubic meter can use heat, equivalent to 3.03 kilograms of coal combustion can use heat.
What are the characteristics of methane gasComposition of BiogasBiogas is a mixture of gas, its main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and other components. The biogas composition, combustible components including methane, hydrogen sulfide, carbon monoxide and heavy hydrocarbon gases; non combustible components including two carbon monoxide, nitrogen and ammonia gas in the methane. In the composition of methane content is 55% ~ 70%, the carbon dioxide content is 28% ~ 44%, the average content of hydrogen sulfide was 0.034%.
