Abstract: A method and apparatus is provided for the thermolysis of solid waste within an enclosed thermolysis chamber in the absence of free oxygen which produces a thermolysis off-gas. The thermolysis off-gas is removed from the thermolysis chamber and injected into a cyclone where it is washed with water and cooled. The washed and cooled thermolysis off-gas is divided into two portions. One portion of the washed thermolysis off-gas is further cooled in a heat exchanger and then injected into a burner and combusted, while the remaining portion of the washed thermolysis off-gas is passed into indirect heat exchange with the hot off-gas resulting from the combustion of the other portion of the thermolysis off-gas in the burner and recycled back into the enclosed thermolysis chamber. This in-situ recycling of hot thermolysis off-gas helps prevent the creation of hot spots in the thermolysis chamber and the possibility of an explosive reaction between oxygen and hydrogen.

Abstract: System for the treatment of liquid and gas products, the disposal of which is detrimental to the environment. The system has a single thermolysis reactor, a chamber for feeding the liquid or gas products to be treated, an intermediate disk for the passage of the gas to be treated, a thermolysis chamber in which the thermo-catalytic-decomposition takes place and a purification chamber in which are selectively retained for elimination chemical elements released by thermo-catalytic-decomposition.
