4 Performance characteristics:

Coal activity refers to the chemical reactivity of coal and coke towards carbon dioxide, which means the ability of coal to reduce carbon dioxide under certain high temperature conditions; HX-2A type belongs to HX-2

Coal activated upgrading products.

2. Coal with high activity has strong reducing ability; Coal with low activity has poor reducing ability. Therefore, coal activity is one of the indicators that characterize the chemical stability and surface area of coal. Coal gasification

The activity of coal is closely related to gasification and combustion. Coal with high activity has a high reaction block during gasification and combustion, with high efficiency, especially for some new gasification processes with high efficiency

This is especially true for boiling gasification, etc. The activity of coal directly affects the reaction of coal in the furnace, coal consumption, and the effective components in the gas.

3. In the new technology of sulfurization combustion, the activity is also closely related to the reaction rate of coal in the furnace. Therefore, activity is also an important indicator of gasification and combustion characteristics. With technology

With the development of technology, the application of coal activity indicators in production will become increasingly widespread.
