Publication number: 20100276271Abstract: A reactor (9) for the pyrolysis of carbon-containing waste material such as rubber chips includes a cylindrical air-tight reactor vessel (10) which has an inlet through which rubber chips (4) are introduced into the reactor vessel and an outlet (60) through which oil distillate can be discharged therefrom. The reactor vessel has a cooling jacket through which cooling water flows for cooling an inner shell (40) of the vessel. The chips (4) are deposited onto a support tray (70) and displaced towards a rear end of the reactor vessel by a chain conveyer (89). The chips (4) are heated on the tray (40) causing decomposition of the chips into a vapour and amorphous carbon. The vapour condenses when it contacts the inner shell (40) and runs down the sides of the vessel (10) towards a lower side thereof before being discharged through the outlet (60).Type: ApplicationFiled: August 3, 2006Publication date: November 4, 2010Inventor: John Lindsay Dinnematin

Patent number: 7749359Abstract: A reactor is provided for converting organic material to charcoal, with the reactor having a furnace and a retort extending through the furnace. The retort has an auger extending therethrough, with the auger having a flight with gaps therein. Members project inwardly from the walls of the retort at the gaps in the flight to unplug blockages in the retort. A gas collection system is provided which has a branched portion having two or more venting tubes, each with valves so that each may be shut off independently to allow to off-line cleaning without requiring shutdown of the system. A method for converting organic material may be practiced by introducing combustible materials into the reactor.Type: GrantFiled: April 24, 2006Date of Patent: July 6, 2010Assignee: 0752831 B.C.

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: 7692050Abstract: The present invention addresses the processing of waste and low-value products that contain bone material to produce useful materials in reliable purities and compositions, at acceptable cost, and with high energy efficiency. In particular, the invention comprises a process that converts various feedstocks such as offal, animal manures, and municipal sewage sludge, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process heats the feedstock in order to breakdown proteins and separate organic material from bone material, applies further heat and pressure to the resulting liquid mixture, separates out various components, then further applies heat and pressure to one or more of those components. The invention further comprises an apparatus for performing a process of converting waste products into useful materials, and an oil product that arises from the process.Type: GrantFiled: September 29, 2004Date of Patent: April 6, 2010Assignee: AB-CWT, LLCInventors: Terry N. Adams, Brian S. Appel, Craig Timothy Einfeldt, James H. Freiss
