| 摘 要： | 利用高通量动力学反应器测量了本征条件下钴基费托催化剂上反应物消耗速率rCO和产物生成速率rCH4随固定床床层的分布,并考察了它们在不同入口分压(p0CO,p0H2)条件下的变化.结果表明,入口氢碳比(H/C)0=p0H2/p0CO为影响速率的敏感外部变量,反应速率随(H/C)0的增加而加快；而合成气总压p0H2+CO则...

| Abstract: | The syngas consumption rate rCO and CH4 production rate rCH4 along a fixed-bed reactor for Fischer-Tropsch synthesis were measured via a high-throughput kinetic reactor under different inlet pressure(p0H2,p0CO) . The data showed that within non-diffusion limited regime the feed ratio p0H2/p0CO is the determining variable while p0H2+CO is non-sensitive. The bed-level intrinsic rate measured under various inlet pressure can be used to establish the pellet level rate-law. The results showed that for rate law u... |
