Coking Process - an overview | ScienceDirect Topics

The flexicoking process is a development of the fluid coking process where only 2 wt% of coke is produced, thus most of the coke is used to heat the feed. A fluidized bed is added to the process which acts as a gasifier in which steam and air are injected to produce synthesis gas called Low Btu Gas (LBG) as shown in Figure 6.10 .

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 ...

What is a Coke Oven? (with pictures)

 · In the coke-making process, treated coal is placed in the coke oven. Due to the high temperature inside, coal gas, coal water, and tar are separated from the coal. The gas and water then fuse together with carbon and the remainders of ash. The hard residue that remains at the end of this process is commonly referred to as coke.

Can We Make Steel Without Coal? - Coal Action Network Aotearoa

 · Steel is made in a subsequent process as an alloy of iron and carbon (along with some other elements). Around 1% of the carbon from the coke remains in the raw iron to provide the source of that carbon. So coal (as coke) is a reducing agent, a source of energy to drive the process and a source of carbon to incorporate in the steel.
