Brown coal solid fuels

The other types of cheap ammonium nitrate explosives to made on the spot by mixing ammonium nitrate with cheap solid fuel such as carbon black, peat, brown coal etc. were also suggested in the U.S.A. They are much less popular than AN-FO. 

Chemical composition of waste plastic cracking products depends on shares of the individual polymers (PE, PP, PS) in the feed and process parameters. This fact decides the technological application of the final products. Important products of the cracking process, both petroleum fractions and waste plastics, are coke residues. Coke residue yield increases considerably, up to 10 wt%, in cracking of municipal and industrial waste plastics since they contain various inorganic impurities and additives. It can be applied as solid fuel, like brown coal. In the fluid cracking the solid residue is continuously removed from the process by combustion in a regenerator section. 

In the pinewood experiments, the fuel nitrogen is almost completely converted into NH5, with HCN and solid bound nitrogen being negligible considering experimental errors. The conversion of fuel nitrogen into NH3 with the brown coal experiments is... 

Lignite. Lignite, a member of the solid fuel family, is often referred to as brown coal. Table 15.8 shows that lignite fits between peat and bituminous coals in terms of its properties. It is drier than peat and has a higher carbon content.

Brown coal humic acids can be regarded as a model substance of the organic matter of low rank coals (12). Therefore, the results obtained in the present study migh be relevant to similar carbonaceous adsorbents based on solid fuels. 

Although it constimtes only about 0.09 percent by mass of Earth s crust, carbon is an essential element of living matter. It is found free in the form of diamond and graphite (see Figure 8.17), and it is also a component of natural gas, petroleum, and coal. (Coal is a natural dark-brown to black solid used as a fuel it is formed from fossilized plants and consists of amorphous carbon with various organic and some inorganic compounds.) Carbon combines with oxygen to form carbon dioxide in the atmosphere and occurs as carbonate in limestone and chalk. 

Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible. Naphthalene was first extracted from coal tar in 1819 by English chemist and physician John Kidd (1775- l85i). Coal tar is a brown to black thick liquid formed when soft coal is burned in an insufficient amount of air. It consists of a complex mixture of hydrocarbons, similar to that found in petroleum. Kidd s extraction of naphthalene was of considerable historic significance because it demonstrated that coal had other important applications than its use as a fuel. It could also be utilized as the source of chemical compounds with a host of important commercial and industrial uses. Naphthalene s chemical structure was determined by the German chemist Richard August Carl Emil Erlenmeyer (1825-1909). Erlenmeyer showed that the naphthalene molecule consists of two benzene molecules joined to each other.
