Patent number: 7371308Abstract: The invention describes a process and a plant for pyrolyzing hydrocarbon-containing waste products, in particular used tires or biowaste, in which the material to be pyrolyzed is introduced into a pyrolysis furnace and is pyrolyzed at 500° C. The significant factor is that the material is introduced as far as possible without being broken down, into a receiving device outside the furnace (1), which receiving device is introduced into the pyrolysis furnace, which is open at the bottom, from below, the device simultaneously closing the furnace (1) in a sealed manner. The significant advantage is that a plurality of different receiving devices for different materials can be provided, so that the pyrolysis plant can be used with a relatively quick changeover for different pyrolysis raw materials, without changeover measures on the furnace being required.Type: GrantFiled: August 2, 1999Date of Patent: May 13, 2008Inventors: Eva Maria Hackl, legal representative, Leopold Hackl

Patent number: 7341646Abstract: A low energy method of pyrolysis of rubber or other hydrocarbon material is provided. The hydrocarbon material is heated while maintaining a vacuum, using a clay catalyst. In an additional embodiment, also under a vacuum and optionally with or without the catalyst, the temperature of the reaction chamber and corresponding fuel input is varied either over time or spatially within the reaction chamber, to take advantage of the exothermic properties of the reaction. With the method of the present invention, an improved solid reaction product can be achieved.Type: GrantFiled: December 17, 2004Date of Patent: March 11, 2008Assignee: RJ Lee Group, Inc.Inventors: Ronald E.

Patent number: 7101464Abstract: A microwave distillation apparatus provides destructive distillation of whole waste tires. The apparatus includes a housing including a plurality of vertically arranged chambers. A preheat chamber provides preheating of a whole waste tire received therein. An irradiation chamber, located below the preheat chamber and thermally coupled to the preheat chamber such that heat generated in the irradiation chamber creates heat convection currents in the preheat chamber, receives a preheated whole waste tire from the preheat chamber. A microwave energy supply supplies microwave energy to the irradiation chamber to provide destructive distillation of a tire received in that chamber. A cooling chamber, located below the irradiation chamber, receives by-products of the destructive distillation therefrom and provides delivery of the by-products from the housing.Type: GrantFiled: May 9, 1997Date of Patent: September 5, 2006Assignee: The Tire Chief, Inc.Inventor: Joe Allen Pringle

Patent number: 6830597Abstract: The subject invention pertains to unique and advantageous systems for gasifying and/or liquefying biomass. The systems of the subject invention utilize a unique design whereby heat from a combustion chamber is used to directly gasify or liquefy biomass. In a preferred embodiment, the biomass is moved through a reactor tube in which all the gasification and/or liquefaction takes place. Preferably, char exits the biomass reactor tube and enters the combustion chamber where the char serves as fuel for combustion. The combustion chamber partially surrounds the reactor tube and is in direct thermal contact with the reactor tube such that heat from the combustion chamber passes through the reactor wall and directly heats the biomass within the reactor tube.Type: GrantFiled: February 18, 2000Date of Patent: December 14, 2004Assignee: Green Liquids and Gas TechnologiesInventor: Alex E.
