Coal, annual production

Chinese coal production and consumption situation as Table 1 shows. From the year 2008 to 2012 the production and consumption increased continuously, and coal production possessed more than 75% of national total energy, coal consumption scale more than 70% due to the influence of macro-economy, the coal consumption scale decreased to 66.5% in 2012, but the coal annual production capacity will be raised to 4,100 million tons in 2015 from the data of coal production and consumption and the Twelfth Five-year energy plan demonstrated that coal (as the disposable resource) demand will appear to be zero or negative increase situation, but the annual production capacity will be increased continuously. So the conclusion can be drawn that the contradiction between coal supply and demand will obviously appear and the economy situation not sound. 

Commercial shale ok production in the People s RepubHc of China is stkl being carried out in Fushin and Maoming. However, production in both areas is declining because of continued emphasis on conventional petroleum and coal. Annual shale ok production in China is about... 

It is the largest unit worldwide based on solid fuels. The plant has been operating since 1996 and can process up to 2600 ton/day of coal/petcoke fuel mixed with limestone (2 wt%) and produces 180,000 m3/day of raw gas. The annual production of slag (85% of the ash in weight) and fly ash (15% of the ash in weight) are respectively 120,000 ton and 12,000 ton per year. The demonstration project has now attained commercial development with a gross efficiency of 47.2%... 

By substituting only 15% of its fossil fuel needs with solid hazardous waste fuel, a modern dry-process cement plant with an annual production capacity of 650,000 tons of clinker can save the energy equivalent of 50,000 barrels of oil (or 12,500 tons of coal) a year. Southdown typically replaces 10-20% of the fossil fuels it needs to make cement with hazardous waste fuels. 

Each year the US electric utility industry generates over 1500 billion kWh of electricity from the combustion of over 800 Mt of coal (Wang Sweigard 1996). The combustion of this coal leads to the generation of approximately 110 Mt of coal combustion products (CCPs) annually (ACAA 2000). The total mass of CCPs produced in the USA now ranks among non-fuel mineral resources such as crushed stone, sand, and gravel. 

An aromatic compound which is employed along with glycerol in the production of alkyd resins is phthalic anhydride. The conventional process for the manufacture of this chemical has been from the catalytic oxidation of coal tar naphthalene, and annual production of the anhydride in recent years has been around 150,000,000 pounds. In 1946 production was started (4) in a plant of the Oronite Chemical Co. at Richmond, Calif., to produce phthalic anhydride by the oxidation of o-xylene produced in a hydroformer unit of the adjacent Standard Oil Co. of California refinery. The Oronite plant was reported to have a design capacity of 7,000,000 to 8,000,000 pounds per year of 99.7% pure phthalic anhydride.

Depending on the desired or feasible rale of annual production, the amounts of coal reserves required to support a new mine designed for an economic life of 20 years or more may range from a comparatively few ions to 300 million ions or more. Such amounts are dependent upon the... 

Coal contains most of the elements of the periodic table, the majority of which are present in concentrations of 100 ppm or less. Many of these trace elements are toxic to plant and animal life, even at low levels. Because U.S. power plants consune on the order of 600 million tons of coal annually for the production of electricity (1), coal combustion can mobilize thousands of tons of potentially hazardous trace elements into the environment each year. Due to the large quantities of coal combusted, even trace amounts of toxic elements present in the coals can accumulate to hazardous levels. Also, potentially deleterious effects of particulate emissions from coal combustion may be enhanced since many trace elements are surface-enriched (2) and concentrate preferentially in the smaller, more respirable particle sizes (3). Substantial amounts of some elements, such as As, Hg, and Se, are in the vapor phase in flue gases from coal combustion and are essentially unaffected by most particle control devices. Aside from the potential detrimental environmental aspects, trace elements in coal can pose adverse technological... 

Early developments for producing liquid fuel from coal which can be found in many countries took place in the 1840s in Germany and England. They were the first steps of the petrochemical industry. These processes produced kerosene to fuel German airplanes during World War II and supplied up to 90% of the demand in liquid fuels at that time. Sasol s plants in the Republic of South Africa are the only industrial coal-to-liquid production capability that remains today with an annual production of 7.5 M tonnes of liquid fuels (gas oil, kerosene) and chemical products.

Over a period of almost a century activated carbons have remained the most widely used of all the general-purpose industrial adsorbents. In 1995, the world annual production of activated carbons was estimated to be in the region of400 000 tonnes, with consumption increasing at about 7% per annum (Derbyshire et al., 1995). They are manufactured from a variety of precursors, but cheap and readily available materials such as wood, peat, coal and nut shells are still generally used for large-scale production (Baker, 1992). 

About half of the ammonia produced in the United States is made from coal. Assuming that coal contains 1% nitrogen, 30% of which can be recovered as ammonia, what weight of coal is treated for the annual production of 100,000 ions of ammonium sulfate in this way ... 

From coal tar by distillation there are obtained a number of aromatic compounds. Upon coking, a ton of soft coal may yield about 120 pounds of coal tar. From this 120 pounds the following aromatic compounds can be separated benzene, 2 pounds toluene, 0.5 pound xylenes, 0.1 pound phenol, 0.5 pound cresols, 2 pounds naphthalene, 5 pounds. Two pounds of benzene from a ton of coal does not represent a very high percentage yield, yet so much coal is coked every year that the annual production of benzene from coal tar is enormous.
