Coke formation during thermal reaction of tar from ...

01/01/2017  These behaviors were recently attributed to the countercurrent flow of heat and volatiles in coal particles and in pyrolysis reactors . The ... Considering the fact that Tar-21s is easier to form coke than Tar-2s as shown in Fig. 3, the activation energy of Tar-21s should be lower than of Tar-2s, so the zero-order and zero-order + autocatalytic kinetics are more suitable to describe the coking ...

As the raw coke oven gas is cooled, tar vaporcondenses and forms aerosols which are carried along with the gas flow. These tar particles would contaminate and foul downstream processes and would foul gas lines and burner nozzles if allowed to continue in the gas stream. The tar precipitators typically use high voltage electrodes to charge the tar particles and then collect them from the gas by ...

Coal gasification - Wikipedia

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...

How is Crude Coal Tar Derived 1

Crude Coal Tar is a by product of the Coking process. Coking is the process of heating coal in coke ovens to drive volatile matter from it. Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferro-alloys, elemental phosphorus, calcium carbide and numerous other processes. It is also used to produce carbon electrodes and to agglomerate sinter and iron ore ...

A reclaimer then feeds the coke from the wharf to a conveyor belt, which transfers the coke to the crushing and screening station. During the distillation process, a large amount of gas and smoke is generated, which –after purification– creates coke oven gas and other valuable by-products, such as tar, sulphur, ammonia, naphthalene and benzole.
