Patent number: 8322056Abstract: Methods and systems for preparing a torrefied biomass fuel are disclosed. Moisture is initially extracted from relatively wet biomass fuel to produce a relatively dry biomass fuel.

The biomass material is preheated by injecting into the feeding duct super-heated: dry steam. A condenser within the enclosure reduces resulting vapors into oils that can be drained from the enclosure pan. Solid combustion residue is abstracted from the enclosure by an Archimedes screw.Type: GrantFiled: August 18, 2004Date of Patent: September 19, 2006Inventor: Vincent H. Noto

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: 7087140Abstract: A carbonizing waste processing apparatus is operable to rotate and heat a radiant tube for carbonizing waste therein so as to generate granular char and vapors from the waste, transfer waste into an upstream end of the tube, temporarily impede movement of the waste through the tube at upstream and downstream locations therein so as to ensure that residence time of the waste in the tube is sufficient at the upstream location to carry out evaporation of moisture from the waste and at the downstream location to elevate the temperature of any solids in the waste for completion of carbonization of the waste, discharge the granular char and vapors from the tube, and flow the generated and discharged vapors through a succession of finned heat exchanger tubes so as to condense and separate the vapors into oil, water and methanol.Type: GrantFiled: August 12, 2002Date of Patent: August 8, 2006Inventor: Harry H. Menian

Patent number: 7056422Abstract: A distillation system is provided for batch thermolytic distillation of lump carbonaceous material, such as lump wood and shredded rubber tires. The system preferably includes multiple distillation units mounted side-by-side. Each unit includes a reactor bath for holding molten tin at approximately 455° C., a two-compartment reservoir for storing molten tin, and a porous basket pivotally mounted within the reactor bath for tipping motion. A process for batch thermolytic distillation of lump carbonaceous material includes rotating the porous basket into a reactor bath by rotating the basket about an axis passing through the reactor bath; putting a charge of wood into the basket; closing a retractable lid onto the reactor bath; filling the reactor bath with molten material to produce gas and char by thermolytic conversion of the charge, draining the reactor bath of molten material while the lid is closed; quenching the char in the reactor bath with steam; opening the lid; and tipping the char from the basket.Type: GrantFiled: April 17, 2003Date of Patent: June 6, 2006Assignee: Sector Capital CorporationInventor: William Dell'Orfano

Patent number: 7025006Abstract: The invention relates to an industrial and/or household waste treatment method and to an industrial and/or household waste treatment installation (1). According to the invention, the method is characterised in that it consists of, in particular, the loading of the waste into numerous pierced containers (20), thermolysis of the waste in the containers (20) being conveyed into a pyrolysis oven (12); emptying of the containers (20) into a separation tank (18) in order to separate the products formed by the thermolysis; and treatment of the separated products.Type: GrantFiled: March 20, 2002Date of Patent: April 11, 2006Inventor: Patrick Jeulin

Patent number: 7008459Abstract: A process and apparatus for coal pyrolysis pretreatment. The apparatus is made up of a pretreatment vessel for holding a bed of coal particles, a preheater for heating the bed of coal particles to a temperature below the coal pyrolysis temperature range and an oxygen remover for removing oxygen released from the heated coal particles. The apparatus can also have a flue gas source as an oxygen removal sweep gas to the bed of coal, a collector for collecting non-condensable combustible gases, and the preheater having a furnace holding ceramic balls which are circulated from the furnace to the bed of coal particles. The process involves heating the bed of coal particles to a temperature below the coal pyrolysis temperature range and preventing air from contacting the bed of coal particles in addition to collecting non-condensable combustible gases or the preheating step accomplished by having a furnace holding ceramic balls which are circulated from the furnace to the bed of coal particles.Type: GrantFiled: April 9, 1997Date of Patent: March 7, 2006Inventors: Arthur P. Fraas, Richard L. Furgerson, Harold L. Falkenberry

Patent number: 6666955Abstract: An improved method and apparatus is disclosed for reclaiming volatile products and non-volatile residue through the pyrolysis of a polymeric material comprising placing the polymeric material in a reactor and establishing an oxygen deficient atmosphere in a reactor. The polymeric material is simultaneously compressed and heated to a temperature sufficient to pyrolyze the polymeric material to produce volatile products and non-volatile residue. The volatile products and non-volatile residue are subsequently removed from the reactor and collected.Type: GrantFiled: July 7, 2000Date of Patent: December 23, 2003Inventor: G. Thomas Bissell
