Temperature and heating rate of solid particles undergoing a thermal decomposition. Which criteria for characterizing fast pyrolysis?

Other criteria are also discussed. Among them, reactor temperature and external heat transfer coefficient appear to be more relevant, as well as efficiency of primary products removal. However, it is shown that the definition of fast pyrolysis reactor optimal conditions cannot rely on only one criterion. All implied parameters should be taken into account in a global approach including close couplings between reactor properties and particle pyrolysis behaviour.
