在1678K的温度下测定了用CO或CO与Ar的混合气体还原浮士体的反应速度浮士体放在纯铁坩埚中,还原速度是根据红外CO2气体分析仪所测出的CO2生成量来求出的.实验表明表现还原速度正比于气体中CO分压,并与气体流量的1.59次方有关,反应的前或其速度是由气相的传质速度所控制,化学反应的速度常数最小为60(g/atm·min·cm2).
The rate of reduction of the flotation body with CO or a mixed gas of CO and Ar was measured at a temperature of 1678 K. The float was placed in a pure iron crucible and the reduction rate was based on the amount of CO2 generated by the infrared CO2 gas analyzer Find out. Experiments show that the reduction rate is proportional to the CO partial pressure in the gas and is related to the 1.59 th power of the gas flow. The reaction speed is controlled by the mass transfer rate of the gas phase, and the minimum of the chemical reaction rate is 60 g / atm · min · cm 2).
