摘要
为评价不同气化方案对印刷线路板熔融盐气化的影响,针对印刷线路板的熔融盐气化反应过程建立了反应动力学模型.模型计算结果表明,气化反应体系首先发生CO、H2和焦炭的氧化反应,生成较大量的CO2和H2O,此后反应体系内CO2和H2O与焦炭进行氧化还原反应而逐渐减少,在参加反应的焦炭被消耗完全后,反应体系随着水气变换可逆反应的平衡而达到平衡.
To evaluate various PCB molten salt gasification schemes, a predictive model for molten salt gasification of printed circuit boards （PCB） is proposed based on reaction kinetics. The calculated results show that in the gasification reaction system in molten salt the initial oxidation reaction produces CO, H2 and char, which then generates a large quantity of CO2 and H2O. Then the CO2 and H2O are reduced by the remaining char, generating CO and H2 until the char is consumed, and then the reaction system is finally balanced with the balance of the water gas shift reaction.
