Patent number: 11046891Abstract: 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.Type: GrantFiled: July 22, 2019Date of Patent: June 29, 2021Inventor: Jürgen Buchert

Patent number: 8409303Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.Type: GrantFiled: February 11, 2011Date of Patent: April 2, 2013Assignee: SGC Advisors, LLCInventors: Norman L.

Publication number: 20080148628Abstract: 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.Type: ApplicationFiled: September 13, 2007Publication date: June 26, 2008Inventor: JURGEN BUCHERT
