Question

what is differnce between pyrolysis and calcinaton??​

Answer 1

Essentially calcination is decomposition at high temperature with inorganic reactants such as calcium carbonate in making cement.
CaCO3−→ΔCaO+CO2

Pyrolysis is decomposition or oxidation at high temperatures of organic materials such as cellulose in making charcoal.
(C6H12O6)−→ΔC7H4O+CH+H2O

Answer 2

Answer:

Essentially calcination is decomposition at high temperature with inorganic reactants such as calcium carbonate in making cement. $$\ce{CaCO3 ->[\Delta ] CaO + CO2}$$ Pyrolysis is decomposition or oxidation at high temperatures of organic materials such as cellulose in making charcoal. $$\ce{(C6H12O6)_{n} ->[\Delta] C7H4O + C_{x}H_{y} + H2O}$$ where $\ce{ C_{x}H_{y}}$ is volatilized byproducts.
