Wood pyrolysis with molten salt as heating medium.

Abstract

Sapwood of konara (Quercus serrata) was pyrolyzed in molten carbonates and chlorides and in an inert atmosphere without molten salt at temperatures of 873-1173K, respectively. By the use of molten salt, the yields of wood gas and residual char were increased while that of distillate was decreased. The concentration of hydrogen in the gas was increased by the use of mixtures of carbonates or a mixture of zinc chloride and potassium chloride. The concentrations of methane and ethylene were increased by use of a mixture of sodium chloride and potassium chloride.
