coke from brown coal

Producing non-blast furnace coke from brown coals of the ...

The physicochemical characteristics of the fuels used in the experiments are presented. The brown-coal semicoke differs considerably from coke fines in properties; the semicoke has higher reactivity than the fines, and it burns in air at 500 K. For comparison, the ignition temperature of coke fines is 1200 K.

Attempts have been made to obtain a substitute for blast furnace (BF) coke from a Victorian brown coal mixed with a tar derived from brown coal under conditions sufficiently mild to be economical. Changes to the procedure used in a previous attempt include hot briquetting of the coal-tar mixture at 150 °C rather than ambient, the addition of ...

Blast furnace coke substitutes from Victorian brown coal

2017-1-23  Iron is usually produced from its ores using coke in a blast furnace (BF). Coke, a hard and macroporous carbon material, is produced from special coals (coking coals) and acts as fuel, smelting agent, and the permeable support for the charge to the BF. No material can completely replace coke in a BF. Coking coals are becoming harder (and more expensive) to obtain. Victorian brown coal (VBC) is ...

2016-6-1  Victorian brown coal (VBC) can be mined by open cut and, so, is cheap. It also contains little inorganic material, which is a favourable factor for iron production in a blast furnace , , . At present, the cost of coking coal is about USD112–116/tonne compared to about USD35/tonne , for brown coal dried by conventional methods.

Coal and Coke - URM-Company

Brown coal is a solid pit coal formed from peat. The youngest type of coals contains 65-70 % carbon and is brown in colour. It is used as a domestic fuel and a chemical feedstock. This coal has a high water content (43 %) and therefore a low heat of combustion. It also contains a large number of volatile substances (up to 50 %).

While both take the same amount of time to process, a full stack of brown coal will only yield 8 coke, while an equal amount of black coal will yield 12 coke. To start the process, simply layer coal in the oven, ignite with a torch and close the coke oven door ...
