Chapter 4 - Methane production 4.1 Microbial consortia and biological aspects of methane fermentation 4.2 Molecular biology of methanogens 4.3 Developments in bioreactor technology References Methane fermentation is a versatile biotechnology capable of converting almost all types of polymeric materials to methane and carbon dioxide under anaerobic conditions. This is achieved as a result of the consecutive biochemical breakdown of polymers to methane and carbon dioxide in an environment

Hydrocarbons – Methane (Alkanes) Introduction to Hydrocarbons – Methane Carbons have the ability to form many different compounds. Compounds of carbon that only contain carbon and hydrogen are known as hydrocarbons. Most hydrocarbons naturally occur in the mixture crude oil. There are three main types of hydrocarbons‚ alkanes – saturated hydrocarbons made up of only single bonds‚ alkenes – unsaturated hydrocarbons with one or more double bond/s‚ and alkynes – unsaturated hydrocarbons with one or

Normally‚ people think CO2 is the chief source that affects global warming; however‚ methane is more dangerous than CO2. Among the total emissions in 2013‚ which was 6‚673 million metric tons‚ carbon dioxide took around 82%‚ while methane was 10%. It seems methane doesn’t occupy much of gas emissions. However‚ the potential power of methane weighs than CO2’s. The level of methane in the air has gradually increased by man-made activities. Methane’s live in the atmosphere is 12 years (EPA‚ 2010). This

Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ and the principal component of natural gas. Methane’s bond angles are 109.5 degrees. Burning methane in the presence of oxygen produces carbon dioxide and water. The relative abundance of methane makes it an attractive fuel. However‚ because it is a gas at normal temperature and pressure‚ methane is difficult to transport from its source. It is generally transported in bulk by pipeline in its natural gas form

author Lisa Margonelli examines what methane hydrates are‚ the capabilities of methane hydrates‚ and the potentially detrimental affects methane hydrates can have on global warming. Methane hydrates exist in the seabed along coastlines around the world and are massive deposits of gas that are trapped in large‚ icy structures underneath the coastal sea floor. Despite inadequate funding‚ scientists around the world are conducting experiments to determine if methane hydrates can serve as a solution to

Global Warming is caused by many things. The causes are split up into two groups‚ man-made or anthropogenic causes‚ and natural causes. Natural Causes Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth’s atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40‚000 years.

The Combustion of Diamond and Methane Methane is a hydrocarbon compound that is found in a gaseous state at room temperature. It has the chemical formula CH4‚ it is an odourless‚ colourless gas that is a large percentage of ‘natural gas’ and is a large contributor to global warming as it is a greenhouse gas and is flammable so is used as a fuel. Methane is a product of the covalent bonding of carbon and hydrogen. Products of the combustion of methane include carbon dioxide‚ water‚ soot and carbon

Methane hydrate is a crystalline solid which consists of methane molecules inside the crystal structure. The methane molecules are trapped inside the cage-like structure of solid water‚ ice. Methane hydrate looks like ice‚ but it would burn and release energy when it is close to a flame. That is why it also called fiery ice. There are three types of crystal structures of methane hydrate which are determined by the number of water molecules inside the crystal. There are structure with 46‚136 and
