30 Key Pros & Cons Of Coal E&C

Coal is one of the most important energy sources in order to meet our global energy demand. It has been used over the past decades and significantly improved our overall wealth. However, coal also has many serious downsides. In this article, the pros and cons related to the use of coal are examined in detail.

The Release of Trace Elements in the Process of Coal Coking

The tested charge coal was not only different in the trace elements contents but also in the release coefficient values. Since the pyrolysis conditions were similar, it may be assumed that the release process is affected by other factors such as chemical and mineralogical form, in which trace elements contained in coal are found, and the contents and composition of mineral matter in coal.
