Synthetic coking coal is produced by coking heavy hydrocarbons at a temperature greater than the temperatures which initiate cracking in the coker and by removing the gaseous and liquid products from the coker at accelerated velocities. The thermally cracked oil produced in the coking reaction can be hydrodesulfurized to produce a low sulfur fuel oil.
· complete the combustion process 1 4 . In the course of a coking process (which proceeds under negative pressure) the amount of air provided to the spaces above and below the coal bed is controlled by underpressure (suction) generated using either a fan or through natural draft caused by a stack. The entire coke making process can be con
Process and apparatus for coking coal using microwave radiation . United States Patent . Abstract Coal either as coal fines or as coal briquettes is introduced into a coking chamber and is thereat exposed to microwave radiation to transform the coal into hot coke. Preferably the microwave radiation is
· The process of heating of prepared coking coal charge or blend of coking coals in absence of air to a due to formation of highly crosslinked macro molecular structure which will not easily melt and flow during heating. In this study 2 types of coal Prime and medium coking coal
The coking process consists of heating coal in the absence of air to drive off the volatile compounds the resulting coke is a hard but porous carbon material that is used for reducing the iron in the blast furnace. The modern byproduct coke oven recovers volatile chemicals in
· Coal charge contraction occurs during two different phases of the process of coking. The first phase is present during plastic layer formation and is mainly dependent on coal properties. Once the plastic layers have transformed to semicoke the second phase begins during the shrinkage of the semicoke and is mainly dependent on the operating
Coking coal also known as metallurgical coal is used to create coke one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world ranging from brown coal or lignite to anthracite. The property that really sets coking coals apart from other coals is its caking ability which is the specific

· Coke Oven Coking Process Brief The coke pusher car takes raw coal from the coal tower stamps and presses them to coal cakes then pushes the coal cakes into the coking chamber. The coal cakes are coked in the coking chamber for a coking cycle s high temperature carbonization. After the coal cakes are totally coked inside the coke will be
· 2. Monitoring of Gas Generation during the Coking Process In the cokemaking process coal is carbonized in coking chambers of a coke oven battery maintained at about 1000 ℃ during which process the coal softens as its temperature rises melts and solidifies again to turn into coke having sufficiently strength high for charging

Figure Flow sheet of coking of coal Functional role of each unit (Figure ) (a) Coal crusher and screening At first Bituminous coal is crushed and screened to a certain size. Preheating of coal (at 150250˚C) is done to reduce coking time without loss of coal quality.
· Direcsil technology is basically a highspeed thermaloxidative coking achieved by fast heating of coal by means of combustion of its volatile components. Modeling of coal processing conditions simulating the real coking process was carried out in Tamman furnace which is a hightemperature resistance furnace with vertical graphite tube.
