Activity tests of methane dry-reforming were conducted using a catalytic wall-plate reactor (CWPR). As reported in previous work, the CWPR can suppress channel blockage by carbon deposition. The prepared CWPR can be used to investigate the influence of molecular diffusion, convective flow and reactions on the reactor performance by changing the reaction channel's dimensions. Necessary constraints are expressed in universal form by a dimensionless modulus as the modified Peclet number and the second Damköhler number ≪ 0.1, and through reaction tests and kinetics analyses. The CWPR can be scaled up easily by multiplying channels and/or stacking multiple plates. The CWPR will help to develop compact chemical processes, such as methane dry-reforming as conducted in this study, which require long operation times without channel blockage.

通道尺寸和操作参数对催化壁板反应器中甲烷干重整反应的影响及其设计方法

使用催化壁板反应器（CWPR）进行甲烷干重整的活性测试。如以前的工作所报道，CWPR可以抑制由于碳沉积而造成的通道阻塞。制备的CWPR可用于通过改变反应通道的尺寸来研究分子扩散，对流流动和反应对反应器性能的影响。必要的约束条件通过无量纲模量表示为修正的Peclet数和第二Damköhler数≪ 0.1，并通过反应测试和动力学分析以通用形式表示。通过增加通道和/或堆叠多个板，可以轻松按比例放大CWPR。CWPR将有助于开发紧凑的化学过程，例如本研究中进行的甲烷干重整，这需要较长的运行时间而不会堵塞通道。
