Methane

Methane is the simplest of alkanes and the main combination of natural gas. Methane was discovered by Alessandro Volta between 1776 and 1778. Methane is used to heat homes and cooking stoves. Methane gas causes choking. 

The name of matter (Persian): Methyl hydrate or Mud gas 

English name: Methyl hydride or Marsh gas 

Brand Name: Methane 

Brand name: Methane 

Methane is a chemical compound with the formula CH4. It is the simplest alkane and the main combination of natural gas. The bonding angle of the methane molecules is 109.5 degrees. Methane burning in oxygen produces carbon dioxide and water. The relative abundance of methane and its pure burning have increased the popularity of this fuel. But since methane is in normal gas conditions, its transfer to a difficult and costly consumer. Natural gas is transported either by pipeline or LNG. In the methane structure, each of the four hydrogen atoms is connected by a covalent bond, that is, with a pair of electrons subdivided into a carbon atom. When the carbon is connected to four other atoms, its orbitals (sp3 orbital blends consisting of an orbital s and three orbital p) are oriented toward the four-faced corners. This four-faced arrangement is a cosmetic that allows orbitals to distance each other from one another. In order to make the orbitals overlap with the spherical orbitals of the hydrogen atom so that a stronger bond is formed, each hydrogen core should be placed in a four-cornered corner. The tetrahedral structure of methane is confirmed by electron diffraction, which shows the arrangement of atoms in these simple molecules clearly. Methane was discovered between 1776 and 1778 by Alessandro Volta during the study of Lake Maggiore Flood gases. 

Indications: 

Methane is a basic substance in the petrochemical industry and is used in conjunction with propane (L.P.G. Gas Liquid) for fuel and energy uses.

Natural gas resources: 

The main source of methane is natural gas. Methane in natural gas comes with some hydrocarbons and sometimes helium and nitrogen gas. Gas at shallow levels is produced by anaerobic digestion of organic matter. In general, burned debris produces gas at higher temperatures than oil is produced. 

Alternative sources: 

Apart from natural gas, methane can be produced by biogas production by decomposing organic materials such as agricultural fertilizers, waste water, solid municipal waste and any biodegradable material under anaerobic conditions. Methane gas can also be obtained for industrial use by some chemical reactions from atmospheric and hydrogen gas. 

Safety information: 

Methane gas does not stimulate the eyes and skin. Methane gas At high concentrations, takes oxygen place and causes choking. Methane gas is flammable.
