Introduction Methane is a chemical compound which has the chemical formula CH4. It is the main constituent of the natural gas (50% - 90%) and this is the reason why it is considered as a very important chemical compound in Qatar which depends economically on the exportation of natural gas. On the other hand it has many harmful effects on the earth such as global warming. Methane was discovered by Alessandro Volta in 1776 when he read some papers about flammable air which pushed him to study more

The concentrations of methane in the atmosphere have doubled recently, which is why it is important to us to reduce emissions of methane. The major source of methane in the atmosphere is produced by anthropogenic activity, such as forest and land burning and in the digestive process of ruminant animals. Methane production from ruminant animal is affected by two main factors: digestibility of the feed and quantity of
They think it gone for good, but scientists worry that if methane increases in the atmosphere, it could cause more warming than carbon dioxide when they burn the fossil fuels. It is important to know because of the methane from landfills because it is estimated that it causes between thirty and seventy million tons of emissions every year (Reay, n.d.). It is necessary to understand the sources and advantages, and disadvantages, of methane because it is dangerous because it can affect the environment
Anthropogenic Sources of Atmospheric Methane Introduction The atmosphere has always contained the Greenhouse Gas methane. Along with carbon dioxide, nitrous oxide, and water vapor, methane helps to create the natural greenhouse effect. These gases trap some of the sun's energy and keep the Earth at a warm enough temperature to sustain life. If the occurrence of any of these gases in the atmosphere is increased, the natural greenhouse effect will intensify and further warm

for 18% of the GHG emissions. In contrast, transport makes up just 13% of the world’s greenhouse gas footprint. Moreover, cows turn out methane gas which is 23 times as damaging as CO2. Furthermore, livestock rearing utilizes 30% of the earth’s surface. In light of this, Johnson suggests that Dr.Pachauri is perhaps correct to be anxious about emissions of methane gas from livestock. Boris affirms that: although Dr.Pachauri’s scrutiny was accurate; his proposition to cut down on meat was ridiculous
the only efficient option to fill our needs. Although cattle produce methane, they aren’t a large contributor of greenhouse gasses. Feedlot cattle produce less greenhouse emissions than grass fed/organic cattle, and feedlots work to reduce methane emissions. Although cattle do prodce me ethane, it is not a large enough amount to have a significant affect on the planet. According to the EPA cattle only produce 1.5% of the methane in the atmosphere. That is not a very large percentage, especiaally
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours. A typical composition of biogas can be seen on the following table: Table 1: Biogas typical composition Component Formula Concentration (% by vol.) Methane CH4 55-70 Carbon dioxide CO2 30-45 Nitrogen N2 0-5 Oxygen O2 <1 Hydrocarbons CnH2n+2 <1 Hydrogen sulfide H2S 0-0.5 Ammonia NH3 0-0.05 Water (vapour) H2O 1-5
process that used to produce benzene. The reaction occurs as: Toluene + H2 Benzene + CH4 The process need toluene and hydrogen as a main reactor. Then, toluene and hydrogen are converted in a reactor packed with catalyst to produce benzene and methane. This reaction is exothermic and the operating conditions are 500 0C to 660 0C, and 20 to 60 bar of pressure. This process begins with mixing fresh toluene with a stream of recycle unreacted toluene, and the mixing is achieved in a storage tank.
atmosphere, Methane makes a very capable and effective greenhouse gas . Methane, which is transparent in UV and visible spectral regions, displays absorption bands which complements Titan’s infrared emission spectrum. The cycle of methane on Titan is still a mystery and needs further research gain more understanding, however it seems to be very similar to of water on Earth. Also another efficient greenhouse gas is Molecular hydrogen, which also absorbs the infrared and enact a similar role to Methane. Many

A typical reaction for the process is given in equation below, in which carbon is converted to carbon monoxide and hydrogen.

Oil and natural gas companies have developed a way to drill for natural gas, a process called hydraulic fracturing, also known as fracking. Natural gas is a flammable gas mixture consisting of methane and several other hydrocarbons that occur naturally underground. Natural gas is used as fuel for heating, cooking, and even in some automobiles like the “RideOn” buses. This technique has only recently become economically feasible with the rising prices of fossil fuels, and there is much potential
produced at least 1600 pounds of municipal solid waste (MSW) in fiscal year 2005 and more than 54 percent of the wastes disposed in landfills the amount of 140 million tons of waste. This amount of waste has potential to produce toxic gases, CO2, Methane, greenhouse gas (GHG), metals volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and toxic poisonous soup called leachate along hundreds of other contaminants. By using dump and old landfills, these pollutants became serious
The atmosphere is something that is around us everyday, but do we really think about the changes that occur in it. It isn't that we just aren't paying attention, but more of the fact that it is hard to notice slight changes over long periods of time. Everyday gases are released into the air by all living material. The gases in the air are used for many important things. For example, hydrogen is released by volcanoes, which can give energy to the cell; photosynthesis has evolved to take
environmentally friendly in terms of the time it take to decompose but there are many more cons to bio-plastics than pros. The cons that outweigh the short decomposing time scale are methane emissions, recycling problems and food price inflation. One of the biggest issues is that when these plastics decompose in land fill they release methane. Now, one of the most beneficial factors of bio-plastics is the time it take to decompose in a land fill and does not harm to the soil. This plastic takes only weeks to
The Role of Livestock Farming in Global Warming Livestock farming plays an integral role in the lives of individuals all over the world. Despite the magnitude of animal agriculture, research on its environment effects has been severely lacking in the past. Recent studies have shown that greenhouse gas emissions from livestock play a much bigger role in global warming than was once thought (Gill, 2009; Miller et. al 2013). The session that I propose will look at the greenhouse gasses emitted by livestock
absorption method was discovered in the 1800s. Therefore, this measurement limit scientist to analyse the climate change from 1800 to recent. For example, there will be a higher peak for methane in the data shown recently compared to the measurement done in the past. This suggests that there is a change in the amount of methane gas present in the atmosphere which has led to a discussion of climate
being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns. People need to get educated and recognize
One of the biggest issues the world faces today is global warming. As oceans warm up, ice caps and glaciers melt, causing land along coasts to flood. As temperatures shift, animals migrate, making symbiotic relationships out of sync. The effects of global warming are small, but it is estimated that within a hundred years, the earth will be the hottest it has ever been. Throughout history, people have learned that carpooling and recycling will save the world from global warming. Although it helps
