Coal and Coke Analysis
A coal inferior somewhat on these tests to a good steam coal may be recommended, if otherwise favourable, in preference to the good coal, provided the difference of prices on delivery more than counterbalances these deficiencies. Analysis of Coal. Sample the coal, and obtain a 20 gm. sample which has passed through a 100 mesh sieve.

PURPOSE: To prepare needle coke which shows a low degree of expansion in graphitization, by adjusting the quinoline insolubles content of raw material oil to a specified level and coking it by a delayed coking process. CONSTITUTION: A raw material oil consisting of hydrocarbon, such as coal tar, is introduced through a feeding pipe 1' and is mixed with solvent in a mixer 1.

The residue is chiefly carbon, with minor amounts of hydrogen, nitrogen, sulfur, and oxygen. Also present in coke is the mineral matter in the original coal, chemically altered and decomposed during the coking process. Oven coke (size: 40 to 100 millimetres, about 1 1/2 to 4 inches) is used throughout the world in blast furnaces to make iron.

Coal preparation, coking, and slaking in China and Japan
In China and Japan, measures have been developed to maintain constant coke quality and hence permit economical and stable blast-furnace operation with the injection of coal-dust fuel; and to reduce the cost of the coke, despite the continuing shortage of high-quality coking coal. These approaches include the construction of large-capacity coke batteries, with minimal …

In this study formed coke was prepared using devolatilized coal at different temperature. The effect of use of this devolatilized coal was studied in terms of point crushing strength. In general, it was observed that higher devolatilization temperature (550 °C) and longer duration (3 hr) increases the point crushing strength and fixed carbon.

Difference Between Coal and Coke
Coal is baked in an airless furnace at a very high temperature (above 2000 degrees Celsius) to remove water, gas and coal-tar, and at the end of the coking process, it contains zero amount of water. However, later small amount of water can be absorbed by the porous structure. Coke is useful as a fuel in stoves and furnaces.

coal preparation,
• Coke is white, lustrous, dense porous mass. Depending on the behavior of coal, when heated in the absence of air, the coal is classified into: 1. Non-coking coal which undergoes practically no fusing effect and also called as free burning coal. 2. Coking coal which gives porous, hard and strong residue after heating in the absence of air.
