目前沼氣還無(wú)法應(yīng)用壓縮儲(chǔ)存。不是技術(shù)問(wèn)題，主要是經(jīng)濟(jì)利用價(jià)值低。沼氣的單位經(jīng)濟(jì)價(jià)值比較低，而且不能高密度儲(chǔ)存。
At present, biogas can not be compressed. It's not a technical problem, it's mainly a low economic value. The unit economic value of biogas is relatively low, and it can not be stored in high density.
例如：當(dāng)沼氣壓縮到50倍后，里面的二氧化碳很容易在密閉的鋼瓶中液化或者固化，因此很少在市場(chǎng)上使用壓縮液化沼氣。由于受市場(chǎng)因素及其他因素有限，目前還不能實(shí)現(xiàn)規(guī)模化沼氣壓縮儲(chǔ)存。相信在不久的將來(lái)沼氣提純壓縮儲(chǔ)存一定會(huì)得到廣泛的普及應(yīng)用，走向市場(chǎng)。
For example, when the biogas is compressed to 50 times, the carbon dioxide in it is easy to liquefy or solidify in a closed steel cylinder, so compressed liquefied biogas is rarely used in the market. Due to the limited market factors and other factors, the large-scale compressed storage of biogas can not be realized at present. It is believed that in the near future, biogas purification and compression storage will be widely used in the market.
沼氣是有機(jī)物質(zhì)在厭氧環(huán)境中，在一定的溫度、濕度、酸堿度的條件下，通過(guò)微生物發(fā)酵作用，產(chǎn)生的一種可燃?xì)怏w。由于這種氣體開(kāi)初是在沼澤、湖泊、池塘中發(fā)現(xiàn)的，所以人們稱(chēng)為沼氣。沼氣含有多種氣體，主要成分是甲烷(CH4)。是一種很好的清潔燃料。
Biogas is a kind of combustible gas produced by microbial fermentation under certain temperature, humidity and pH in anaerobic environment. Because this gas was initially found in swamps, lakes and ponds, it is called biogas. Biogas contains a variety of gases, the main component is methane (CH4). It's a good clean fuel.
沼氣產(chǎn)生的化學(xué)方程式：
The chemical equation of biogas production is as follows:
①由CO2和H2產(chǎn)生甲烷反應(yīng)為 ：CO2 4H2—CH4 H2O
① The reaction of methane from CO2 and H2 is CO2 4h2-ch4h2o
② 由乙酸或乙酸化合物產(chǎn)生甲烷反應(yīng)為：
② The reaction of methane from acetic acid or acetic acid compound is as follows:
CH3C00H—CH4 CO2 CH 3COONH4 H20—CH4 NH4 HCO3
CH3C00H—CH4 CO2 CH 3COONH4 H20—CH4 NH4 HCO3
