Carbon dioxide in Earth's atmosphere atmosphere, oceans, soil, rocks, and volcanism. Both carbon cycles are intrinsically interconnected and atmospheric gaseous carbon dioxide facilitates the carbon cycle. Natural sources of atmospheric carbon dioxide include volcanic outgassing, the combustion of organic matter, wildfires and the respiration processes of living aerobic organisms. Man-made sources of carbon dioxide include the burning of fossil fuels for heating, power generation and transport, as well as some industrial processes such as cement making. It is also produced by various microorganisms from fermentation and cellular respiration. Plants, algae and cyanobacteria convert carbon dioxide to carbohydrates by a process called photosynthesis. They gain the
Coal gasification commercialization resulting from the gasification of feed coal is shifted, and a Rectisol process is utilized for sulfur removal and CO removal. Recovered CO is sold for use in making carbonated beverages. "Lignite gasification to produce synthetic natural gas or ammonia" The Great Plains Synfuels Plant (GPSP) in Beulah, North Dakota has been in operation since 1984 producing synthetic natural gas (SNG) from lignite coal, and remains the only coal-to-SNG facility in the United States. GSPS is operated by the Dakota Gasification Company. In addition to the production of SNG, the plant also produces high purity carbon dioxide, which is distributed
