Publication number: 20100140074Abstract: Combustible material is supplied to the reaction zone, continuously or in pulses, which the reaction zone is separated from the surrounding atmosphere, and combustible material gradually moves through the reaction zone to the reaction zone outlet, in the same direction as released gases leave the combustible material. The reaction zone is heated to the temperature, the value of which is increasing in the direction to the reaction zone outlet, however, to 12000 C as a maximum. Then, released gases are draught off separately from non-gasified residue. As an advantage, steam and/or water is supplied to combustible material and the combustible material previously charged into the reaction zone moves by acting of subsequently supplied combustible material, where the combustible material is being compressed. The equipment for pyrolytic conversion comprises one filling device (1), reactor (2) comprising the reaction zone (5), at least one heater (3, 13), and hopper (4) for non-gasified residue (8).Type: ApplicationFiled: May 12, 2008Publication date: June 10, 2010Inventors: Václav Holusa, Petr Vanicek, Ivan Koutnik, Miroslav Kaloc

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: 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

Publication number: 20020029996Abstract: Used oil is treated in a reactor to remove contaminants. The reactor comprises a rotating vessel housed within a heating chamber. The inside of the vessel is indirectly heated by conduction through the vessel walls. The vessel contains a permanently resident charge of non-ablating, coarse granular solids. Within the vessel, the oil is vaporized and pyrolysed, producing a hydrocarbon vapor. Coke is formed as a byproduct. Contaminants, such as metals and halides become associated with the coke. The coarse granular solids scour and comminute the coke to form fine solids. The fine solids are separated from the coarse solids and are removed from the vessel. The hydrocarbon vapors are separated from any fine solids and are routed to a vapor condensation system for producing a substantially contaminant-free product oil. The contaminant-rich solids are collected for disposal.Type: ApplicationFiled: May 22, 2001Publication date: March 14, 2002Applicant: Alberta oil sands Tech and Research AuthorityInventors: William Taciuk, Steve Odut, Gordon Taciuk, Charlie Wheeler

Publication number: 20010032780Abstract: The present invention relates to an apparatus and method for withdrawing and dewatering slag from a gasification system. In particular, the present invention relates to a conveying lockhopper and method of using the conveying lockhopper to collect slag and other waste byproducts from the gasifier of a gasification system. The conveying lockhopper is configured to receive slag from a gasifier, simultaneously extract and dewater the slag, and expel the processed slag directly into an awaiting container suitable for carrying the processed slag away. The conveying lockhopper generally comprises a housing with inlet and outlet valves to receive and expel slag, respectively. The housing is inclined at an angle typically between 5 and 60 degrees to the horizontal so that the outlet is at a higher elevation than the inlet. Inside the housing, an auger or similar conveying mechanism conveys the slag from the inlet towards the outlet while simultaneously dewatering the slag.Type: ApplicationFiled: February 13, 2001Publication date: October 25, 2001Inventors: John D. Winter, Rajasekar Kamarthi, Thomas F. Leininger, Katherine S. Lee, Chih-Hao M. Tsang, Pravit Vassantachart

Patent number: 4261795Abstract: This disclosure is directed to an economical system for the pyrolysis of municipal solid waste to recover valuable by-products while reducing the putrefaction and bulk of the residue requiring disposal. Prior to this treatment, the solid waste has been processed to remove most of the metallic components, and shredded, which steps are not part of the invention disclosed. The pyrolysis and by-product recovery technology is complicated by (a) the inherent variability of the chemical and physical characteristics of the shredded solid waste as received at the pyrolysis plant and (b) the relatively low heat value of said waste as thus received.Type: GrantFiled: November 16, 1979Date of Patent: April 14, 1981Inventor: Bertram B.
