Activated carbon (AC) has a number of attractive characteristics, such as its high adsorption capacity, high hydrophobicity, low cost, and low energy requirement for regeneration [117119]. Absorption is an important technology for CO2 separation. Amines react rapidly, selectively, and reversibly with CO2 and are relatively nonvolatile and inexpensive solvents. When comparing emissions of different gases, these indicators use a concept called global warming potential to convert amounts of other gases into carbon dioxide equivalents. 9, pp. These methods include electrochemical pumps and chemical looping approaches to CO2 separation. 7, pp. How Is Climate Change Impacting The Water Cycle. "There is no real alternative that is proven," said Prof Manu Haddad from the school of engineering at Cardiff University. The CaO-MgAl2O4 and nano CaO/Al2O3 are the best chemical adsorbents. The program also collects data from entities known as "suppliers" that supply certain fossil fuels and industrial gases that will emit greenhouse gases into the atmosphere if burned or releasedfor example, refineries that supply petroleum products such as gasoline.

Polymeric membranes are very selective for CO2 separation but they have low thermal stability. 103104, 2009. Wang et al. In oxy-fuel combustion, nearly pure oxygen is used for combustion instead of ambient air, and this results in a flue gas that is mainly CO2 and H2O, which are separated by condensing water. U.S. By the result of this study, future research direction on the scale-up and industrialization of adsorption (with modified adsorbent), and membrane process for CO2 separation is suggested. Because PZ solubility in water is low, concentration of PZ is between 0.5 and 2.5M. Rosas et al. The required process equipment is very simple, compact, relatively easy to operate and control, clear process and easy to scale up [187, 188]. Official websites use .gov However, nanomaterials always have high production cost with complicated synthesis process such as carbon nanotubes and graphite nanoplatelets [99, 100]. 108116, 2012. Major emission sources of these today are from industries such as electric power generation, magnesium production, semiconductor manufacturing, and aluminum production.

[180] reported that conversion of O2/CO2 cycle was more efficient than amine scrubbing but more difficult to implement because of the specific gas turbine. A wide range of metals have been studied including [89](i)metal oxides: CaO, MgO,(ii)metal salts from alkali metal compounds: lithium silicate, lithium zirconate to alkaline earth metal compounds (i.e., magnesium oxide and calcium oxide),(iii)hydrotalcites and double salts. 14901495, 2013. EPA is working with industry to reduce emissions through the SF 6 Emission Reduction Partnership for Electric Power Systems , which promotes leak detection and repair, use of recycling equipment, [165] prepared different adsorbents based on the central composite design (CCD) with three independent variables (i.e., amination temperature, amination time, and the use of preheat treated (HTA) or preoxidized (OXA) sorbent as the starting material). VSA is preferred to the special PSA application where the desorption pressure is below atmospheric, whereas in TSA, the temperature is raised while pressure is maintained approximately constant, and in ESA the solid is heated by the Joule effect [166169]. When they reach the mesosphere 37 miles (60 km) above the Earth's surface, high-energy ultraviolet electromagnetic energy destroy them, but it is a very slow process, which enables them to accumulate in the atmosphere for several thousand years (up to 50,000). The reaction of CO2 adsorption with Li2ZrO3 is reversible in the temperature range of 723863K. Adsorption capacity of this adsorbent is presented in Table 4. 26102628, 2010. J. Brouwer, P.
