  • Patent number: 6814940
    Abstract: The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention, the feedstock is fed into a fluidized-bed reactor, wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor and the regenerator comprise risers having an axially annular cross section and being equipped with multi-inlet cyclones for the separation of particulate matter. By means of the invention, it is possible to producer pyrolysis oil, the quality of which is higher than that of oil produced with the processes of the prior art.

  • Publication number: 20040108251
    Abstract: A method for processing carbonaceous material in a reactor. Carbonaceous material, such as sawdust, plant residues from forestry or agricultural processes, municipal solid waste and refuse derived fuel, is fed into the riser section (10) of a reactor (10-15) in which it is contacted with inorganic particulate material and reactor walls at an elevated temperature essentially in the absence of oxygen in order to convert the carbonaceous material at least mainly into gaseous processed products, whereby a gas phase is obtained, containing fluidization gas and processed products. According to the invention a dense suspension is formed into the riser space (10) of the reactor, containing based on the particle number 7×108 to 3×1011 particles/m3 (about 2×107-1×1010 particles/ft3), and the mass ratio between the particulate matter bringing heat into the reactor and the carbonaceous material is in the range of 1:1 to 10:1.

  • Patent number: 6294104
    Abstract: The present invention relates to an environmentally friendly liquid for the prevention of freezing of aircrafts and runways, said liquid being particularly suitable to various spraying equipments. The vapor pressure of the said liquid is less than 5 Pa, and the acute oral toxicity, LD50, is more than 10 000 mg/kg. This anti-freezing liquid comprises 10-60 wt. % trimethyl glycin or derivatives thereof, and 40-90 wt. % water, and optionally additives known for anti-freezing liquids.

  • Patent number: 5665211
    Abstract: In an electrolysis apparatus according to the invention for producing hydrogen by decomposing electrolysis liquid with the aid of electric current into hydrogen and oxygen in a pressurized electrolytic cell (11), an electrolytic cell (11) is placed within a liquid-filled pressure shell (10) maintained pressurized with the pressure of a gas produced in electrolysis. The liquid can be selected, for instance, among the following group: silicon oils or fats, fluorized oils, crude oil-based or synthetic oils, or water.

  • Patent number: 5128221
    Abstract: A storage battery (10) comprises several cells (1) enclosed within a housing, each cell containing electrolyte and plates coated with positive mass, negative mass, and positive and negative mass on different sections thereof. The cells are separated from each other with separator plates (14), and the requisite electrically conducting connectors are provided for connecting the plates and/or cells. Each cell (11) contains positive and negative plates (12,13,15). Each cell (11) is packed in an individual electrically insulating housing (16) so that merely the ends (12a,13a) of the plates (12,13) need to be electrically interconnected, respectively. The ends (12b, 13b) of the plates (12,13) are connected to the terminals (17,18) which emerge from the housing (16) to be electrically connected. For providing electrical conductivity, the spaces between the cells (11) and the end walls of the outer cells (11) are made electrically conductive with an electricity conduction joint (19).

  • Patent number: 5037671
    Abstract: In a method for manufacturing storage plates, plate frames (5) of storage batteries are material-coated by active material supply means which is provided with at least one rotating material application wheel. The wheel includes a dispensing element (14) with which the active material is dispensed to a conveyor belt or equivalent means which travels under the supply means (10) and conveys plate frames (5). The material application wheel/wheels (11,1a) of the supply means (10) is/are rotated at such a high speed that the material application wheel/wheels (11,1a) dispenses/dispense the active material (1) from the dispensing element (14) to the mobile conveyor belt (20) under the effect of centrifugal force. The invention also concerns a means for manufacturing storage batteries.

  • Patent number: 4973533
    Abstract: The present invention concerns a gas vault structure for a storage battery having one or several cells enclosed in a housing, each cell containing electrolyte and monopolar plates and/or bipolar plates separated from one another by separator plates and coated with positive and/or negative mass, along with requisite electrical connectors interconnecting cells and/or plates. The gas vault structure is arranged to serve as an inner core for producing a gas space during casting of the housing of the storage battery, and/or of the cover, and/or of the partitions separating the cells.
