• The obtained results showed that the effect of external diffusion could be slackened by the decrease of fixed-bed voidage and the increase of space velocity.

    计算结果表明,银催化剂空隙减小或操作空速的增加有利于减弱该催化反应过程中外扩散效应的影响。

  • A comparison of VFB and CFB indicates that VFB has lower minimum fluidization velocity, higher bed voidage and more steady fluidization because big bubbles can not be formed in the bed.

    由于层中没有气泡生成,普通流化床(CFB)相比VFB具有初始速度大的床层空隙率,而且流化稳定
