- Abstract:
-
Based on the core of the core, this article made a suitable simplified hypothesis on the sulfide reaction, and the square and the difference between the calculation value of the reaction rate and the experimental value was the target function, and the Powell method returned to the appropriate refractory model parameter. The test found that at high altitude, the sulfurization process of the raw cobalt molybdenum catalyst was taken to obey the core size. Under excessive situation, h_2s is a first -level reaction. The relationship between the activation energy and temperature of the return obeys the law of Arangnius.
