PROCESS AND PLANT FOR CONVERTING WASTE PLASTIC MATERIAL INTO COMBUSTIBLE HYDROCARBONS

摘要

Process and plant (10) for conversion of plastic material waste (44) into combustible hydrocarbons comprising thermal separation, at about 450 DEG C and ambient pressure, of said plastic material waste (44) and its transformation into liquid material and then into combustible gaseous hydrocarbons, expulsion of residual material consisting of heterogeneous impurities and separation in a catalyst (80), with AL*** salts, metal oxides, SiO3<=>, of said gaseous hydro-carbons into a lesser quantity of gaseous hydrocarbons of small molecules such as CH4 and C4H10 and the like and in a greater quantity of liquid hydrocarbons consisting of a mixture of petrol and fuel oil.
