Migration behavior of alkali metal chlorides upon heating
Thread Content
The flash point of alkali metal NaCl is 1413 degrees, and that of KCl is 1500 degrees. What is the migration pattern of these two salts in the gas stream when they are added to the raw coal in a pressurized gasification environment?
Even if what you add is sodium chloride or potassium chloride； It is not released in the form of sodium chloride or potassium chloride; due to the reducing atmosphere and the presence of numerous functional groups, chlorine begins to be released at temperatures above 300 degrees, while sodium and potassium probably start to volatilize at temperatures above 500 degrees. The whole process is quite complex. It depends on the reactor type.
I remember that in the catalytic gasification process at Xinnuo, a certain salt component is added, and the catalyst can be recovered later
What is the migration mechanism in a gasifier or in a multi-effect evaporator?
