Coal Carbonization - an overview ScienceDirect Topics

Coal carbonization is an extremely complicated art. The methods have been developed through centuries of trial and experience. More detailed descriptions on the processes involved can be found in the literature 16]. Modern foundry or blast furnace coke is made in a battery of up to 100 slot ovens placed side by side. Individual ovens are typically 16 meters long, 6.5 meters high, and about 0.5 ...

Coal pollution mitigation - Wikipedia

Coal pollution mitigation, sometimes called clean coal, is a series of systems and technologies that seek to mitigate the health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry.. The primary focus is on sulfur dioxide (SO 2) and nitrogen oxides (NO x), the most important gases which caused acid rain; and ...

The Carbonisation of Coal SpringerLink

Carbonisation is the term used to denote the heating of coal in the absence of air. In these circumstances, volatile matter (VM) is removed. The volatiles are higher in hydrogen content than the basic coal, which therefore increases in carbon — hence, “carbonization”. As noted elsewhere, the off-gases can be useful; fuel gases and chemical feedstocks, especially benzene, can be separated ...

Coal utilization - Carbonization (coke making) Britannica

Coal utilization - Coal utilization - Carbonization (coke making): Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making. High-temperature carbonization, with which this section is concerned, is practiced to produce a coke ...

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 ...

Evaluation of coal carbonization processes - NASA/ADS

Agglomeration of the coal during carbonization can be prevented by a variety of methods. An attractive approach appears to be the bed recirculation method. Desulfurization of the liquid and char products can be achieved by additional treatment with hydrogen. The reported survey shows that a number of processes for the carbonization and hydrocarbonization of bituminous coals are available ...

Coal liquefaction - Wikipedia

Methods. Specific liquefaction technologies generally fall into two categories: direct (DCL) and indirect liquefaction (ICL) processes. Direct processes are based on approaches such as carbonization, pyrolysis, and hydrogenation.. Indirect liquefaction processes generally involve gasification of coal to a mixture of carbon monoxide and hydrogen, often known as synthesis gas or simply syngas.
