我们继七十年代研制成功CD—1型(800℃,30 at),CD—2型(550℃,常压)无梯度反应器并投入使用之后,又研制了CD—3 型高压内循环无梯度催化反应器,适用于550℃,300at气固相催化动力学研究。CD-3型反应器的工作原理和基本结构CD—3型高压内循环无梯度反应器如图1所示。其工作原理是:电动机直接驱动的激轮高速旋转,驱使高温下的气流高度湍动地通过催化剂篮中的催化剂床层;不仅使物料达到理想混合,均匀一致,而且增强了传热,温度均匀;在高度湍流下,床层流速分布均匀,并且消除或抑制外扩散过程对反应速率的影响。新鲜的原料气(转化率x=0)
Following the successful development of CD-1 type (800 ℃, 30 at) and CD-2 type (550 ℃, atmospheric pressure) non-gradient reactors in the 1970s, we have developed the CD-3 type high pressure internal circulation Gradient catalytic reactor, suitable for 550 ℃, 300at gas-solid catalytic kinetics. CD-3 reactor working principle and basic structure CD-3 type high pressure within the loop gradientless reactor shown in Figure 1. Its working principle is that the direct drive of the motor drives the high-speed rotating drum to drive the high-temperature airflow to pass through the catalyst bed in the catalyst basket in a highly turbulent manner. This not only makes the material reach the ideal mixture and is uniform, but also enhances heat transfer and uniform temperature Under high turbulence, the velocity distribution of the bed is even, and the effect of the diffusion process on the reaction rate is eliminated or suppressed.
