  • Patent number: 11046891
    Abstract: In a method for thermal processing of catalytically active waste plastics mixture, the mixture is subjected in a receiving tank to a cracking temperature to undergo a cracking reaction. The mixture is transferred to a mixer pump to produce a reaction mixture which is directed into an outgassing chamber of an intermediate tank to produce an outgassed fraction and a non-outgassed liquid fraction. The outgassed fraction to produce fuel is cooled down, and a first portion of the non-outgassed liquid fraction is returned and subjected again to the cracking temperature in the receiving tank. A second portion of the non-outgassed liquid fraction is conducted in a bypass to the outgassing chamber of the intermediate tank for outgassing while fresh mixture is added. Residual matter settling in the intermediate tank is periodically removed.

  • Patent number: 8728416
    Abstract: In a method and apparatus for thermal processing of slurry, the slurry is combined with a bio-mass to produce a mixture which is then subjected to a cracking temperature in a receiving tank, thereby liquefying and allowing the mixture to catalytically undergo a cracking reaction. The cracking reaction which the liquefied mixture undergoes is continued in a mixer pump to thereby produce a reaction mixture. The reaction mixture is outgased in an intermediate tank to separate an outgased fraction from a non-outgased fraction. Subsequently, the outgased fraction is allowed to cool down, thereby producing fuel, while the non-outgased fraction is returned to the receiving tank and subjected again to the cracking temperature. Residual matter of the non-outgased fraction settles in the intermediate tank and is periodically removed.

  • Patent number: 8722948
    Abstract: In a method for thermal processing of slurry, slurry is combined with a bio-mass to produce a mixture. The mixture is subjected in a heated mixer pump to a cracking temperature, thereby allowing the mixture to catalytically undergo a cracking reaction to produce a reaction mixture which is directly outgased in the mixer pump to produce an outgased portion and a solid portion. The outgased portion and the solid portion are separately discharged from the mixer pump; with the low boiling fraction of the outgased portion allowed to cool down for further processing, and the solid portion collected in a residual matter container for further processing.

  • Publication number: 20110233276
    Abstract: A reading unit includes an entry slot for receiving a card and an exit slot for dispensing the card. Arranged between the entry slot and the exit slot is a reader for reading information on the card. A disinfector to disinfect the card is arranged in the interior of the reading unit as the card enters into the entry slot and/or as the card is discharged from the exit slot. As a result, a user of the card is protected against risk of infection.

  • Patent number: 7947858
    Abstract: In a method and apparatus for thermal processing of catalytically active biomass, the biomass is subjected in a receiving tank to a cracking temperature to undergo a cracking reaction. The biomass is transferred to a mixer pump to produce a reaction mixture which is directed into an outgassing chamber of an intermediate tank to produce an outgassed fraction and a non-outgassed liquid fraction. The outgassed fraction to produce fuel is cooled down, and a first portion of the non-outgassed liquid fraction is returned and subjected again to the cracking temperature in the receiving tank. A second portion of the non-outgassed liquid fraction is conducted in a bypass to the outgassing chamber of the intermediate tank for outgassing while fresh biomass is added. Residual matter settling in the intermediate tank is periodically removed.
