Weekly Topic: Discussion on Issues in the Coking Process
Thread Content
The raw coal used in the coking process typically has its ash content controlled through washing； Also, keep the temperature at around 1200 degrees. I would like to ask everyone: if coke is used as a raw material for gasification, what issues might arise from increasing its ash content and maintaining the coking temperature at around 1000 degrees?
Around 1000 degrees can result in the formation of raw coke during coking
Why not just use direct gasification? There’s no need to take this detour.
Upstream, industrial facilities such as coking, methanol production from coke oven gas, and tar hydrogenation have been established.
You can build another gas generator
The situation is as mentioned above: the coke oven production line has already been established, and there is a need to process the remaining coke. Hehe
What’s the situation now? Can’t the coke be sold? Is the coke market that dismal? I still don’t quite understand your question. Your approach is medium- and low-temperature carbonization, but the products of such carbonization still contain semi-coke. Since coke is difficult to sell, does that mean semi-coke is easier to sell? I think your question isn’t clear enough or you haven’t thought it through properly! ! Hope to continue the discussion! !
It is now time to consider semi-coke as a gasification feedstock. Due to my lack of understanding of the coking process, I would like to ask if certain parameters in this process can be adjusted? ! Thank you
Do you mean using a coke oven for medium- and low-temperature dry distillation? There have been no attempts in this area domestically yet!
Pretty much! I would like to ask everyone what problems might arise if the coking temperature is changed from 1200 degrees to around 1000 degrees
I suggest you give it a try and see what happens when you put lignite into the coke oven; this can only be determined through experimentation! !
