Earth’s climate is a complex system of interacting natural components. These components include the atmosphere, the ocean, and the continental ice sheets. Living things on earth—or, the biosphere—also constitute an important component of the climate trends system.
Numerous factors influence Earth’s climate system, some of them natural. For example, the slow drift of continents that takes place over millions of years, a process known as plate tectonics, influences the composition of the atmosphere through its impact on volcanic activity and surface erosion.

Air-blown circulating fluidized bed gasifiers are of interest because they produce a good quality, low calorific value (LCV) gas (4–6 MJ/Nm 3 ) and possess a very high carbon conversion efficiency while allowing high capacity, good tolerance to variations in fuel quality, and reliable operation. The high and homogeneously distributed temperatures and the use of particular bed materials, such as dolomite, favor tar cracking. Successful tar cracking can also be achieved using secondary circulating fluidized bed reactors. Also, successful tests on catalytic tar cracking have been performed, for example, by introducing nickel compounds into the gasifier. Sulfur control is made easier because of the significant reduction that can be achieved by adding limestone or dolomite to the gasifier bed. (more…)

Thermo chemical processing of biomass yields gaseous, liquid, and solid products and offers a means of producing useful gaseous and/or liquid fuels. Biomass gasification is a total degradation process consisting of a sequence of thermal and thermo chemical processes that converts practically all the carbon in the biomass to gaseous form, leaving an inert residue. The gas produced consists of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and nitrogen (N2) (if air is used as the oxidizing agent) and contains impurities, such as small char particles, ash, tars, and oils. The solid residue will consist of ash (composed principally of the oxides of Ca, K, Na, Mg, and Si) and possibly carbon or char. (more…)

Agricultural and forestry residues provide the largest proportion of biomass used for the production of biomas bioenergy. Some estimates suggest that globally available biomass role in the form of recoverable residues represents about 40 Ejyr -1, enough to meet 10% of the total present energy use of 406 Ejyr -1 . However, realizing this potential is limited by factors such as ease and cost of recovery and environmental concerns relating to sustainable land use practices. (more…)

Coalbed methane is produced within a process of oil and petroleum system. A petroleum system usually consists of oil in a sedimentary basin with a hydrocarbon source rock and all related oil and gas sources. Conventional petroleum system comprises of a hydrocarbon-generating source rock slate, with the help of heating and constant burial, resulted gas an oil. Coalbed methane is not same with coal which is originating from coal reservoir. The coal is a hydrocarbon source rock that developed during burial heating into a substance similar in structure to activated carbon. This is an organic substance that is chemically covered or heat-treated to increase micro-pores with a matching increase in the surface to increase gas sorption capacity. Coal produce methane gas and it has the capacity keep gas in place. (more…)

Coal is an important energy source and energy consumption in United States as well as worldwide. It will remain so for many years particularly in many developing countries. Fossil fuels stay as the main energy sources to the U.S. economy, but we can not ignore the importance of coal for decades. Coal production provides the price stability and will continue to be an significant source for electricity generation. Coal utilization is the major source of hydrogen in the coming hydrogen-based energy economy and it will be a crucial source of gas to liquid process of fuels energy.

Natural gas is found mainly in underground reservoirs and in coal beds. Natural gas is a fossil fuel that consist primarily of methane and some smaller amounts of hydrocarbons subtracts like ethane, propane and butane. There might be some inert gas like nitrogen, helium, and carbon dioxide involved and dissimilated into natural gas. The actual mixture composition is varies depending upon the region where that natural gas is found. (more…)
