20100072053 | METHOD FOR PROCESSING AND ALSO RECYCLING SLUDGE - The method according to an example of the invention relates to a method for processing and also recycling sludge which has precipitated from waste in a sediment tank within the scope of the high temperature treatment. This is dried and mixed with preportioned solid plastic materials so that solid conglomerates are formed and returned then to the high temperature treatment of the waste. | 03-25-2010 |
20110132737 | METHOD AND SYSTEM FOR CAPTURING CARBON DIOXIDE FROM BIOMASS PYROLYSIS PROCESS - A system and method for biomass pyrolysis utilizing chemical looping combustion of a produced char to capture carbon dioxide is disclosed. The system includes a biomass pyrolysis reactor, a char combustor, and oxidation reactor and a separator for separating carbon dioxide from flue gas produced by the char combustion. The pyrolysis reactor pyrolyzes biomass in the presence of reduced metal oxide sorbents producing char and pyrolysis oil vapor. The char is separated and combusted in the char combustor, in the presence of oxidized metal oxide sorbents, into a gaseous stream of carbon dioxide and water vapor. The carbon dioxide and water are separated so that a stream of carbon dioxide may be captured. The oxidation reactor oxidizes, in the presence of air, a portion of reduced metal oxide sorbents into oxidized metal oxide sorbents that are looped back to the char combustor to provide oxygen for combustion. A second portion of the reduced metal oxide sorbents is recycled from the char combustor to the pyrolysis reactor to provide heat to drive the pyrolysis. Pyrolysis oil upgrading catalyst particles may be used in addition to the metal oxide sorbents as heat energy carrier particles to improve the quality of the pyrolysis oil vapors produced in the pyrolysis reactor. Also, the metal oxide sorbents may have metals incorporated therein which serve to upgrade the pyrolysis vapors produced during pyrolysis. Non-limiting examples of such metals include Ni, Mo, Co, Cr, W, Rh, Ir, Re, and Ru. | 06-09-2011 |

20130020189 | Method and Apparatus for Liquefaction and Distillation of Volatile Matter within Solid Carbonaceous Material - A method for liquefaction of coal or other solid carbonaceous material includes passing the material through a reformer having a temperature gradient therein, the temperature gradient generally increasing as the material flows down through the reformer. The more valuable volatile components of the material exit the material at their respective vaporization temperatures, and pass out of the reformer for processing in condensers. Some of each fraction of the volatile material flow is re-heated and recycled through the reformer to supply heat to maintain the temperature gradient, the recycling injection occurring at a level below that where the fraction exited the reformer so that the recycled fraction will again pass out of the reformer to be condensed. At the bottom of the reformer, the non-volatile portion of the carbonaceous material is removed from the reformer for further processing or sale. | 01-24-2013 |
20130068605 | SYSTEM FOR USING FLUE GAS HEAT - A system including a pyrolysis unit for pyrolyzing organic material to produce at least pyrolysis oil and coke, a regenerator unit to combust the coke and produce a regenerator flue gas, and a mixer connected to the regenerator unit to mix the regenerator flue gas with air to produce a cooled flue gas. The system may further include at least one heat exchanger connected to the mixer to extract heat from the cooled flue gas, and a conveyer belt in thermal communication with the at least one heat exchanger and operably connected to the pyrolysis unit. The conveyer belt conveys a organic material in need of drying past the at least one exchanger to produce organic material suitable for use as a feed to the pyrolysis unit. | 03-21-2013 |
20130075244 | METHOD AND SYSTEM FOR THE TORREFACTION OF LIGNOCELLULOSIC MATERIAL - A method for torrefaction of biomass using a torrefaction reactor vessel having stacked trays including: feeding the biomass to an upper inlet of the vessel; cascading the biomass down through the trays by passing the biomass through an opening in each of the trays to deposit the biomass on a lower tray; heating the biomass material with an oxygen deprived gas; extracting moisture from below each of the upper trays; as the biomass undergoes torrefaction in the lower trays retaining the gas with the biomass until the biomass falls from the stacked trays to a pile of biomass in the reactor vessel; exhausting gases containing organic compounds through a gas outlet at an elevation between the stacked trays and the pile of biomass, and discharging torrefied biomass from the torrefaction reactor vessel. | 03-28-2013 |
20150136580 | PROCESS FOR PYROLYZING COAL USING A RECYCLED HYDROGEN DONOR - A process for pyrolyzing coal using a recycled hydrogen donor includes introducing a coal feed to a pyrolysis zone and heating the coal feed to a temperature of about 300° C. in the absence of hydrogen. A hydrogen donor solvent is introduced to the pyrolysis zone after the coal feed is heated to about 300° C., and the temperature of the coal feed and the hydrogen donor solvent is increased to about 475° C., while increasing a pressure in the pyrolysis zone to at or above a vapor pressure of the hydrogen donor solvent. At least an aromatic hydrocarbon rich fraction is separated from the coal tar stream and hydrogenated. The hydrogenated aromatic hydrocarbon rich fraction is recycled to the pyrolysis zone as the hydrogen donor solvent. | 05-21-2015 |
