In addition to the significant consumption of coal and lignite, petroleum, and natural gas, several countries utilize modest quantities of alternative fossil fuels. Canada obtains some of its energy from the Athabasca tar sands development (the Great Canadian Oil Sands Project). Oil shale is burned at... 

Physical Properties. Physical properties of waste as fuels are defined in accordance with the specific materials under consideration. The greatest degree of definition exists for wood and related biofuels. The least degree of definition exists for MSW, related RDF products, and the broad array of ha2ardous wastes. Table 3 compares the physical property data of some representative combustible wastes with the traditional fossil fuel bituminous coal. The soHd organic wastes typically have specific gravities or bulk densities much lower than those associated with coal and lignite.

Goal Production. In 1860 world coal production was 122 x 10 t/yr. Production increased to 1140 x 10 t in 1913, giving a 4.2% aimual average rate of increase. The rate has slowed and been erratic since that time. Statistical data on world coal production from 1860 to 1960 is given in Reference 81. World coal and lignite production rose to about 4.7 x 10 t in 1988 (1).

Self-ignition is particularly a risk with lower-grade subbituminous coals and lignite. To avoid oxidation, coal piles should be turned frequently so that heat can vent, and piles should be packed and shaped to nhninhze surface exposure. 

South America and Western Europe). But the large reserves of near-surface subbituminous coals and lignites are also being looked upon as future sources of synthetic fuel gases and liquid hydrocarbons that would augment production of synthetic crude oils from, e.g., Northern Alberta s oil sands (4).

During the Tertiary period which dates back approximately 65 million years. Deposits include the sub-bituminous coal and lignite beds in the Great Plains Province, which includes northeastern Wyoming, eastern Montana, western North Dakota, and northwestern North Dakota. 

Not all these processes need necessarily have been involved in formation of every petroleum or even every ozokerite, but both seem to have required a considerable combination of circumstances, with ozokerite the more complicated of the two. The variations in its composition, as well as its scarcity relative to petroleum, coal, and lignite, were inevitable results.

Sparking fuels fuels that do not yield a coherent cake as residue in the volatile matter determination but evolve gaseous products at a rate sufficient to carry solid particles mechanically out of the crucible when heated at the standard rate usually, all low-rank noncaking coal and lignite may also include those anthracite, semianthracite, and bituminous coals that lose solid particles as described above particles escaping at the higher temperatures may become incandescent and spark as they are emitted (ASTM D-3175).
