Experimental studies using a single pellet high temperature diffusion cell reactor

It is very important to know the effective diffusivities of reactant gases through the porous solid matrices for a diffusion limited reaction. The single pellet high temperature diffusion cell reactor is used to measure the effective diffusivities of argon and nitrogen during the sequence of calcination, sintering, salt addition and sulfation of Greer limestone. This system can be used to study and gas—solid reaction systems where the solid phase undergoes changes between 25 and 1200°C.
