A thermal decomposition apparatus for plastics wherein plastics are melted and thermally decomposed, and the resulting decomposition gas is cooled for condensation and recovered in the form of a thermal decomposition oil. The apparatus comprises a thermal decomposition reactor for melting and thermally decomposing the plastics therein, an extraneous matter discharge duct having one end opened in a melt of plastics within the reactor, an extraneous matter collecting container connected to the other end of the discharge duct, and an aspirator for aspirating extraneous matter within the reactor together with the melt through the discharge duct into the container.

Apparatus for thermally decomposing plastics and process for converting

A method of recovering the heat of reaction for use in chemical heat storage or chemical heat pump systems wherein 2 moles of water vapor is reacted with 1 mole of calcium bromide anhydride to make use of the heat of hydration evolved. The method is characterized by producing water vapor at a high temperature level by heating water in an evaporator with use of the heat of hydration evolved by the hydration reaction of calcium bromide monohydrate into calcium bromide dihydrate in a first reactor included in a plurality of reactors, and supplying the resulting water vapor to a second reactor included in the reactors as water vapor for the hydration reaction of the monohydrate into the dihydrate. The method gives heat substantially at the same high temperature level as the heat of hydration of the anhydride into the monohydrate.
