METHOD FOR CONTROLLING THE CONVERSION OF IRON-CONTAINING REACTOR FEED INTO IRON CARBIDE

摘要

A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a pro- cess gas in a fluidized bed reactor (10), and measurements (56) are taken of individual gases in the off-gas from this reaction and the temperature (64) and pressure (66). A stability phase diagram is generat ed based on the temperature. Different regions of the stability phase diagram are representative of different products being forme d by the conversion of the reactor feed. Based on con- centrations of the individual gases in the off-gas and the total pressure, a point is plotted on the stability phase diagram indicative of the favored reaction product. The process parameters can then be adjusted to insure that iron carbide can be produced from the reactor feed based on the stability phase diagram.
