θ signifies the portion of Energetic websites to the surface in the limestone particles occupied by CO2 made by calcination. The connection amongst θ and CO2 partial force within the gasoline section is displayed in Figure six. It might be viewed that with the rise in CO2 partial tension, the portion θ occupied by CO2 to the particle floor slowly will increase. That is, the R2 desorption technique of the CO2 produced by calcium carbonate with the particle area in the reaction R1 is limited by the increase of CO2 within the gasoline stage. Particularly in the reduced CO2 partial stress stage, θ increases swiftly with the increase of CO2 partial strain.

The diffusion of CO2 through the calcium oxide layer can be explained by Fick’s legislation of diffusion, along with the diffusion circulation price of CO2 is given as:

All TGA products is usually automatic. The sample robot can procedure up to 34 samples even if each individual sample calls for a special process and a distinct crucible.

At this time, the calcination reaction is mainly managed by gas diffusion, such as the gas exterior diffusion stage and the intraparticle diffusion action. Because the particle sizing boosts, the calcination fee decreases speedily; which is, the gasoline diffusion resistance inside the particle and also the exterior fuel diffusion resistance enhance rapidly. While in the particle size variety of 80–450 μm, that is certainly, Zone II, the gas diffusion resistance and chemical reaction resistance are in the exact same order of magnitude, and the calcination system is managed by the two gas diffusion and chemical response.
Optimal atmosphere across the sample is supplied by the created-in mass stream controller fuel source models which are program managed and do not have to have any consumer interaction when commencing an experiment.
The parallel-guided balance makes sure that the situation of the sample will not affect the burden measurement. If the place on the sample variations throughout melting, no modify in body weight takes place.
where by kD would be the diffusion coefficient of CO2 to the bulk atmosphere, which is specified based upon the get the job done of Discipline [48] and Graham [forty nine] and connected to temperature and particle dimensions:
With the rise in CO2 focus, the intraparticle diffusion fee of CO2 produced by particle calcination from the response area on the particle surface area decreases, Particularly at the Original phase in the reaction. Given that the response proceeds, the driving force decreases (Pi-Pg), Pi is near Pg, plus the affect of diffusion is no longer substantial.
