PROCESS OF COMBINED RECOVERY OF MIXED AND CONTAMINATED WASTE PLASTICS

A gasification process for the combined utilisation of mixed contaminated waste plastic (I) comprises injecting liquefied (I) separately, or mixed with hydrocarbons which are liq. at room temp. and/ with less than 40% finely divided solid mineral and/or organic residues, through burner lance(s) into...

Beschreibung
Zusammenfassung:	A gasification process for the combined utilisation of mixed contaminated waste plastic (I) comprises injecting liquefied (I) separately, or mixed with hydrocarbons which are liq. at room temp. and/ with less than 40% finely divided solid mineral and/or organic residues, through burner lance(s) into a fine stream gasifier to produce CO- and H2-contg. gas. The fine mineral components in the mixt. are liquefied and converted into slag; mineral and metallic impurities with a particle size of more than 5 mm are removed from (I) before liquefaction or crushed to below 5 mm, and residues sepd. before liquefaction are used separately in a solid-bed pressure gasification process.
