Rankinite synthesis and pyrolysis inversion

Resumo

The thermal transformation of the pyrolysis–condensation–rankinite synthesis process at a normal pressure is considered in detail. Rankinite pyrolysis is performed with a step-by-step increase in enthalpy (TERRA software system). Rankinite pyrolysis components condense on a surface with temperature Т = 298.15 K. Condensate components are equivalent to pyrolysis components. Wollastonite and limestone can precipitate upon condensation to form a mineral deposit. Synthesis is performed by mixing the condensate components. The components and heat of chemical reactions, the enthalpy, the temperature, and the heat content are determined. It is shown that the decomposition of rankinite (Т_dec = 2598.36 K), wollastonite (Т_dec = 3662.7 K), and limestone (Т_dec = 3680–3810 K) occurs in the process of synthesis and pyrolysis at a constant temperature. The complete pyrolysis–condensation–synthesis process picture typical for various compounds is given.
