  • 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: 8603199
    Abstract: This invention relates to a method and device to produce esterified, olefinated/esterified, or thermochemolytic reacted bio-oils as fuels. The olefinated/esterified product may be utilized as a biocrude for input to a refinery, either alone or in combination with petroleum crude oils. The bio-oil esterification reaction is catalyzed by addition of alcohol and acid catalyst. The olefination/esterification reaction is catalyzed by addition of resin acid or other heterogeneous catalyst to catalyze olefins added to previously etherified bio-oil; the olefins and alcohol may also be simultaneously combined and catalyzed by addition of resin acid or other heterogeneous catalyst to produce the olefinated/esterified product.

  • Patent number: 8409303
    Abstract: 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.

  • Patent number: 8092671
    Abstract: A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.

    Abstract: Processes for converting organic material into renewable fuel products. A feedstock containing organic material is processed at an elevated pressure and temperature to lyse, decarboxylate, and carbonize cell structures. A portion of the processed slurry may be recirculated and mixed with cool, pressurized feedstock prior to reaching a mechanical mixing device to preheat and reduce the viscosity of the feedstock. The pressure and temperature are reduced, which may occur simultaneously to flash volatile materials, such as ammonia, out of the slurry, thereby reducing the presence of the materials in the final product and allowing recovery of the materials. The processed slurry may be treated with a halide to reduce mercury emissions in the final product. The treated slurry is mechanically and thermally dewatered resulting in a renewable fuel product in dried particulate or pelletized form that is a viable energy source having a positive heating value.

    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.
