The Characteristics of Calcium-Based Sorbent Burning Pore Structure and Simulation of Gas-Solid Mass Transfer in Vulcanization

摘要

The experimental is carried out in the normal air atmosphere by calcining CaCO_3 and using the scan electricity speculum and N2 adsorption apparatus to research the ventage structure of the calcinate CaO at 860°C.Analyzing on fractal dimension of different calcination temperature, heating rate and residence time. Thorough the pore structure of CaO which is a porous substance, using "dynamic pervasion modulus" to analyse the Calcium-based sorbent's gas-solid pervasion transferring quality reaction when it is calcined in the furnace. Using the "dynamic pervasion modulus" and revising the expression of the S02 adsorption quality in vulcanizing reaction.
