Coal is becoming an increasingly important factor in the energy resource projections for the remainder of this century. The major use in the generation of electricity is expected to expand as more power plants are converted from petroleum fuels and natural gas to coal. A smaller volume use, the production of metallurgical coke, is expected to increa…
Coal in a aggregate of heterogeneous subtances composed of organic materials. The organic Materials are derived mainly from plant remains which have undergone various degrees of decomposition in the peat swamps and physical and chemical alteration after burial. Optically homogeneous organic materials in coal are called macerals. There are three majo…
The world reserves of coal are larger than those of petroleum and natural gas, and the production capacity for coal currently exceeds that for oil shale, tar sands, peat, and the other less developed fossil energy reserves. As a result, coal is the projected resource alternative for energy and materials well into the next century. whith this increas…
