  • Patent number: 9200225
    Abstract: Relatively high speed methods for increasing the bulk density of coal particles without impacting the coal particles and an apparatus for compacting coal for making metallurgical coke. The method includes depositing coal particles onto a charging plate external to a coking oven. The charging plate has side walls, and at least one movable end wall to provide an elongate bed of dry, uncompacted coal having an upper surface on the charging plate. The uncompacted coal is compacted by passing a vibratory cylindrical compactor along a length of the uncompacted coal for a number of passes sufficient to decrease a thickness of the bed of coal to less than about 80 percent of an original thickness of the uncompacted coal. The vibratory cylindrical compactor has a length to diameter ratio ranging from about 1.4:1 to about 2:1.

  • Patent number: 8980063
    Abstract: A device for proportioning of secondary combustion air into the secondary air soles of coke oven chamber ovens is shown. The device is formed by a slide gate or a parallelepiped device or by plates moved by means of a thrust bar, the thrust bar being moved longitudinally in parallel to the coke oven chamber wall so that the plates move away from the secondary air apertures and open or close these. The thrust bar is moved by means of a positioning motor, with the power transmission being effected hydraulically or pneumatically. Via suitable measuring parameters, it is thus possible to optimize secondary heating so that heating is provided evenly from all sides, thus achieving an improvement in coke quality.

  • Patent number: 8961743
    Abstract: An improved rapid thermal conversion process for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production, is disclosed. In the process, biomass material, e.g., wood, is fed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product.

  • Patent number: 8951391
    Abstract: A solar distillation apparatus utilizing a substantially vertical reactor assembly is disclosed. The reactor includes a tubular outer shell, a base, a cap, and a central tension member. The annular space between the outer tube and the central tension member forms the reactor chamber. Seawater or other feed liquid enters the reactor chamber through the base plate. Reflected or direct solar energy heats the feed liquid, generating low pressure vapor. The vapor exits the reactor through the cap structure or the base. The concentrate left behind settles by gravity to the bottom region of the reactor's liquid column. Extension tubes on the feed openings allow feed liquid to enter the liquid column above the concentrate layer and avoid excessive mixing of the feed liquid and the concentrate. The concentrate exits the reactor through one or more openings in the base.

  • Patent number: 8951390
    Abstract: A reactor for the continuous production of charcoal, having a substantially vertical structure, comprising, in sequence, a top charging zone, a drying zone, a carbonization zone, a cooling zone, and a discharge zone, wherein the charging zone has a smaller cross section than the drying zone and has an extension into the drying zone , forming an annular space around the extension, which space comprises, in the wall of the drying zone, an outlet to a gas extraction line for the recirculation of these gases into the reactor. The reactor reduces sawdust drag by the gases extracted from the preheating zone, without substantially altering the shape and the size of the reactor, which is achieved due to the fact that the charging zone is arranged eccentrically relatively to the drying zone, and that the outlet to the gas extraction line of the drying zone is located substantially on the larger area section of the annular space.

  • Publication number: 20130256114
    Abstract: An apparatus for controlled pyrolysis of waste material includes an elongate, perforated rotary drum lined with refractory material, having a longitudinal axis of rotation, and forming a chamber to receive and decompose the waste material. The drum includes a cylindrical metal exterior which has numerous apertures distributed over its cylindrical surface provided for passage of a limited amount of process air into the chamber. A mechanism is provided for supporting the drum for rotation about the longitudinal axis. An external shell encloses the rotary drum and prevents external ambient air from flowing through the apertures and into the chamber. Air distribution housings are distributed along the length of the rotary drum and form air distribution chambers each of which is enclosed except on an inner side of the chamber. This inner side is open for delivery of process air through a selected portion of apertures in the metal exterior.

  • Patent number: 8419901
    Abstract: 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 practised by introducing combustible materials into the reactor.

  • Patent number: 8419902
    Abstract: Proposed are a system and method for wasteless pyrolytic processing and complete utilization of municipal and domestic wastes. The wastes are sequentially passed through units of sorting, grinding, drying, accumulating, and sending to a pyrolysis reactor for pyrolytic treatment. The syngas produced in the pyrolysis is passed through dry cleaning, dust catching, a first wet cleaning with water, a second wet cleaning with alkali, and a floatation unit for separation of water which is purified to an extent sufficient for technical use. The purified syngas is also passed through an absorber and is then used as a working medium for a power generation unit such as a gas turbine co-generator that generates electricity. Solid products of the pyrolysis reaction, such as coke, are returned to the reactor for afterburning, and the heat of the reaction can be utilized in a dryer, or the like.

  • Patent number: 8323481
    Abstract: A method of sequestering carbon dioxide emissions during recovery of hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. During heating, the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Additionally, during heating, any carbon dioxide that is produced can be sequestered. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.
