Page: Acetogenesis
Acetogenesis the carbonic acids are converted to acetate, H{}2 and CO{}2. Just these substances can be changed directly into methane by methanogenic bacteria. This process is also called "anaerobic oxidation", because electrons in the form of H{}2 are released. The releasing of butyric ...

Page: Acidification
fragments of the hydrolysis are metabolized by facultative and fastidious anaerobes to carboxylic acids like acetic acid, propionic acid, butyric acid, valeric acid and hexane acid. In addition, they are metabolized to alcohol, hydrogen (H{}2) and carbon dioxide (CO{}2). There is a poor ...

Page: Biogas Production
HISTORY{} In 1776 the Italian physicist and nature scientist Alessandro Volta discovered the appearance of methane at the anaerobic degradation of organic matter by connecting marsh gas in the mud of lakes and making combustion experiments. In 1821 the English physicist Michael Faraday identified methane ...

Page: CHP´s with combustion engine
different types of engines: • For smaller plants (< 30 kWel) gasOttoengines are used. These have shorter live time, but lower investment costs. • In the region of 30150 kWel ignition streak aggregates are used. In principal, this are diesel engines. To produce a save mixture, 710 ...

Page: CHP´s with fuel cells
Fuel cells have a high electrical efficiency and low pollutant emissions, comparatively. Because of low number of units they are very expensive. They are working in base of oxyhydrogen reaction: !fuel cell reaction.jpg! By use of a reformer biogas is transformed into hydrogenrich gas. In the fuel ...

Page: Combined Heat and Power Unit (CHP)
most common method biogas is combusted in a gas engine. The rotary motion of the engine powers the generator, which is generating electrical power. It is needful to apply an inverter and a transformator after the generator to feed the electrical power into the public power network. The waste ...

Page: Conditioning
Divers variants of usage expects divers complex pretreatments and conditionings of biogas. Minimum of conditioning is drying and desulfurization. Condensing out the containing moisture happens by cooling the gas. Together with the condensate most of the contamination is retired. For the use of biogas as compensational natural gas ...
