A method is proposed for the desulphurization of sulphur-containing fuels in which the fuels are mixed with at least one solid basic additive and at least one metal in finely divided form, the mixture thus obtained subjected to a pyrolysis and the sulphur adsorptively or chemically bonded to the basic additive separated by methods known per se. The method is particularly suitable for the desulphurization of heavy fuel oil or used oil, and as solid basic additive preferably lime and as metal preferably iron powder are used. The permanent gas forming in the pyrolysis and the simultaneously forming condensate may be directly fired as low-sulphur fuel.

Method for the desulphurization of sulphur-containing fuels and fuel

Method and installation or apparatus for the treatment of material contaminated with toxic organic compounds in which the material is subjected to a thermal treatment to destroy or decompose the toxic compounds, the thermal treatment being carried out in two stages, i.e. a first stage in which the contaminated material is heated to a temperature of not more than 500.degree. C. under pyrolysis conditions in an indirectly heated rotary furnace, and a second stage in which the solid residue remaining in the first stage is heated in a second furnace to a temperature of at least 500.degree. C. until the concentration of toxic organic compounds in the residue is in the ppb range and preferably 1 ppb or less, and in which the gaseous reaction products of the first and second stages are supplied to a combustion chamber and there burnt at a temperature which is sufficient to completely destroy all the toxic organic compounds contained therein.

A method of calcining mineral components such as bituminous limestone in which heat is recovered from the calcining process and is used to liberate volatilizable substances within the mineral matter before the latter is subjected to calcination. The volatilized and pyrolytically decomposed substances form a fuel which is burned to produce the calcining gas mixture.

Method of calcining minerals containing heat-value components

The emission of halogens and sulfur dioxide and the formation of water-soluble compounds of heavy metals are suppressed in the pyrolysis of waste in a carbonization zone at a temperature in the range from 300.degree. to 600.degree. C. by adding a fine-grained basic material to the waste prior to completion of the pyrolysis of the waste in the carbonization zone.

Process for the pyrolysis of waste materials

A process for the pyrolysis of refuse of all kinds wherein the refuse is subjected to carbonization to produce solid residues and raw carbonization gases, the residues and gases are separated, the gases are divided into two parts, one part of the gases is completely burned to produce hot flue gases, the flue gases are mixed with the second part of the raw carbonization gases, the mixture of gases is cracked in a reactor, and the cracked gases are cooled.
