The application of biomass gasification technology is very important in the sense that it helps to relieve the dwindling supply of natural gas from fossil fuels, and the desired product of its gasification process is syngas. 1, similar to that described in our previous work (Peng et al., 2012, Shi et al., 2011), was used to measure the flow characteristics and rheological properties of natural gas hydrate slurries with six different initial water cuts from 5.0 to 30.0 vol%. A person will experience the following effects as gas concentration increases: At 25 to 30% gas in air, the oxygen deficiency can cause ringing ears, euphoria, and unexplained behavioral changes. Coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite.
Gas hydrates are ice crystals with peculiarly structured atomic lattices, which contain molecules of methane and other gases. Other compounds found in natural gas include CO 2, helium, hydrogen sulfide, and nitrogen.The composition of natural gas is never constant; however, the . The molecular weight (MW) of each of the phases in a VLE system is calculated as a function of the molecular weight of the individual components (MWi), provided that both the composition of the gas (yi) and the liquid (xi) are known.
However, those same properties make it potentially dangerous for consumers if their natural gas appliances are not properly maintained. methane (CH. It is found in oil fields and natural gas fields, and in coal beds.

Their gaseous form is mainly the result of high pressure in the altitudes where natural gas is found. This syngas is a mixture of CO and H2; however, by-products such as char, tar, soot, ash, and condensates are also produced.
Physical state : It refers to one of the three common states (gaseous, liquid and solid) of matter that exist at NTP (Normal Temperature and Pressure). Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Their gaseous form is mainly the result of high pressure in the altitudes where natural gas is found.
