电导法自动测量结焦催化剂的再生速率

Automatic Measuring of Regeneration Rate of Coked Catalyst by Conductometry

沉积在催化剂上的焦炭 ,燃烧速度极快 ,尾气中的二氧化碳的浓度又低。针对这一特点 ,设计了一套带有计算机在线测量的电导吸收检测系统 。

According to the characteristic of combustion of coke deposited in catalyst,which has high burning rate and lower concentration of carbon dioxide in the effuent gases,a special experimental system with computer online measurement is designed.Carbon dioxide evolved in combustion experiments is continuously absorbed by a solution of barium hydroxide in a conductivity cell.Computer records frequently the change of electrical conductivity of solution ,so transit burning rates are measured.
