Bituminous Materials

For civil engineering applications, bituminous materials include primarily aphalts and tars. Asphalts may occur in nature (natural asphalts) or may be obtained from petroleum processing (petroleum asphalts). Tars do not occur in nature and are obtained as conden-sates in the processing of coal, petroleum, oil-shale, wood or other organic materials.

Coal

2019-10-13 · Bituminous coal is a dense rock, black but sometimes dark brown. It is a relatively soft coal that breaks and burns readily and quickly. It used as fuel in power stations, and for heat and power applications in manufacturing, for blacksmithing; and to make coke.

Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coalgenerally classified as a metallurgical gradeis harder and blacker and contains more carbon and less moisture and ash than low-rank coals....

() A Review of Microwave Coal Processing

Microwave coal processing is a diverse area, which has the potential to aid in coal upgrading, cleaning and comminution, thus improving efficiency and reducing harmful emissions of coal usage.

2019-10-8 · Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are well ...

The pyrolysis of a bituminous coal at different heating rates can be divided into two stages according to the Coats-Redfern(C-R) plots. The activation energy obtained from the C-R method is 50.2185.14 kJ/mol and 5.147.24 kJ/mol at a heating rate range of 8300 °C/min for the first and second pyrolysis stages, respectively....

2019-10-4 · Bituminous coal is found in veins in sedimentary layers and is one of the two mineral sources of fuel. When processed at a smelter or magma smelter, one unit of bituminous coal produces 9 units of coke. If done at a regular smelter, this processing requires one pre-existing unit of fuel (either charcoal or coke), leaving a net production of 8 fuel....
