Abstract
The process and apparatus for transforming combustible pollutants and waste materials into non-polluting, clean and useful energy, by completely removing the pollutants from raw materials while avoiding the formation of potential pollutants, involve the use of oxygen or a gas mixture containing oxygen, such as air, and steam.
Claims29
A process for transforming combustible pollutants and waste materials into clean energy and useful products, comprising the steps of:
- introducing pollutant and waste material to a thermic lance at a temperature higher than 1600.degree. C. in an airless atmosphere for a time sufficient to totally decompose the material and extract combustible gaseous products based on H.sub.2 and CO, non-combustible gaseous products and inert products, which are forwarded to the subsequent steps,
- cooling all together the thermally decomposed products and separating the inert products with water, thus generating steam and reducing the gases temperature at not less than 1200.degree. C.,
- introducing said steam and said cooled gaseous products onto a depurative carbonaceous mass heated at a temperature higher than 1200.degree. C., to remove the residual pollutants from the gaseous products and to transform the gaseous products, at least in part, into hydrogen, carbon monoxide and other wholly useful gaseous products, and
- cooling the gaseous products coming out from the depurative carbonaceous mass.

An apparatus for transforming combustible pollutants and waste material into clean energy and useful products comprising:
- a) a thermic lance disgregator operating in the absence of air and at a temperature higher than 1600.degree. C. for thermally decomposing pollutants and waste material from a source to form combustible gaseous products based on H.sub.2 and CO, non-combustible gaseous products and inert products,
- b) a water separator to cool all the decomposed products and to separate the inert products with water, thus generating steam and reducing the gases temperature at not less than 1200.degree. C.,
- c) a filter-thermoreactor containing a depurative carbonaceous mass heated at a temperature higher than 1200.degree. C., said filter-thermoreactor being connected to said disgregator and to said separator to remove residual pollutants from the gaseous products and to transform the gaseous products, at least in part, into hydrogen, carbon monoxide and other wholly utilizable gaseous products, and
- d) a refrigerator for cooling said gaseous products coming out from said filter-thermoreactor.
