Definitions

  • the process will decompose not only rice hulls but also wood waste, coal, shale, cotton gin trash, wheat straw, peat, petroleum, coke, paper, peanut shells, coffee grounds, bagasse, municipal solid waste and rubber products such as tires.
  • the biomass material is shredded or otherwise treated so as to reduce the particle sizes to acceptable dimensions.
  • the material may be dried so as to reduce its moisture content.
  • the material is then fed to a pyrolizer or gasifier in the form of a fluidized-bed reactor vessel.
  • the gas for fluidization may be supplied by a positive displacement blower or some similar machine, and pressure relief valves may regulate the pressure in the bed.
  • the yield products of gas, oil and char that leave the vessel are separated by a cyclone separator or some other such device, and the gas and oil may then be used as an energy source for any number of purposes. For example, they may be used to generate steam or could be used to supply the electrical needs of the system.
  • the char may be stored in any suitable facility and may be recycled. The volume of the char is a small fraction of the volume of the original biomass material.
  • FIG. 1 is a block diagram suggesting the various steps in the process of converting biomass materials in accordance with this invention.
  • FIG. 2 is a diagrammatic view of a biomass conversion system utilizing the process of FIG. 1.
  • biomass materials are gasified in a fluid bed reactor vessel to yield clean energy products in the form of oil , gas and char.
  • the amounts of these products produced by the process depend on operating temperature , fluidization velocity and the biomass feed material employed.
  • the clean energy products are the following:
  • gas - Having a heating content between 80 to 300 BTU per standard cubic foot .
  • the gas contains large amounts of carbon monoxide and hydrogen, but it also contains between 10 and 50% water .
  • the gas product can be easily burned in an external combustion system such as a steam boiler or gas turbine.
  • FIG. 1 suggests the several steps of the process of the present invention.
  • the biomass material to be treated is fed to a shredder so as to convert the mass to a suitable size.
  • the shredded material is dried to reduce its moisture content to the moisture limitation placed on the feed material by the gasifier .
  • the material After the material has been pretreated so as to achieve the proper particle size and moisture content , it is fed to a fluidized-bed reactor having an inert bed of material such as refractory sand , alumdun balls , glass , etc. The material is thereafter gasified to yield the clean energy products of oil , char and gas.
  • a fluidized-bed reactor having an inert bed of material such as refractory sand , alumdun balls , glass , etc.
  • the material is thereafter gasified to yield the clean energy products of oil , char and gas.
  • the gasified yield is next conveyed to a separator where the char may be removed from the oil and gas , or all three of the products may be separated from one another .
  • the char is returned to the gasifier to be burned in the fluidized bed .
  • the other products namely oil and gas
  • the electrical energy may be used to run the shredder , dryer , or blower feeding the fluidizing gas , and the steam may be used as a source of heat for the dryer.
  • FIG. 2 a typical installation for carrying out the process is shown.
  • a storage area 1 is suggested where the biomass material (sometimes referred to as feed) is received .
  • This material may typically be in particle sizes in the range of 2.5 x 7.5 cm.
  • the feed is carried by belt conveyor 2 to a shredder 3 to reduce the size of the feed particles to 6 mm or less .
  • the shredder may be of the hammermill type with a capacity of 1.5 metric tons per hour .
  • the biomass material from the shredder is next dropped into a dryer 4, which may include a conveyor screw, to reduce its moisture content below the limitation placed on the material by the system. Normally the content must be reduced to 50% or less by weight.
  • Heat may be provided in the dryer by passing steam through the screws, and this steam may be generated by utilizing the oil and gas products yielded by the system, as suggested above.
  • the dried feed may be conveyed by a wei ⁇ t belt 5 and elevator 6 to the fluidized-bed feed hopper 10.
  • the hopper 10 is connected by an air lock valve 12 and screw feeder 14 to the inlet port 16 of gasifying chamber 18 of reactor vessel 20.
  • the interior walls of the vessel may be lined with a- refractory material, and an inert bed of materials such as sand, alumdu ⁇ balls, glass, etc. is placed on the horizontal, perforated distributor plate 22 before start-up.
  • Tne distributor plate 22 is below the port 16 and separates the upper, fluidizing chamber 18 from the lower, air supply chamber 24 of vessel 20.
  • a fluidizing gas such as air or mixtures of oxygen, nitrogen, carbon dioxide and water is fed into chamber 24 during operation through a port 26 by a positive displacement air blower 28.
  • Tne fluidizing gas for most applications will contain oxygen concentrations in the range of 0 to 21% by volume, but may be further enriched in oxygen when production of higher BTU gas is desired. Heating values of up to 500 BTU/SCF may be attained. Fluidization velocities in the range of .25 to 10 meters/second and pressures in the range of 1-8 p.s.i. are preferred.
  • air is fed through another port 30 from a gas burner 32 which will bring the chamber 18 up to operating temperature of 400 C to 1,100 C in about two hours.
  • the oil/gas product ratio can be adjusted by varying the operating temperatures; for example, with a biomass feed material such as rice hulls, more oil is produced near 500 C, while the gas yield increases and oil yield declines as the temperature goes to 800 C.
  • the gas producted has a heating value of upwards of 250 BTU/SCF.
  • Some char, comprising about 90% carbon, is produced along with the ash and is shown recycled from the cyclone 38 via an ash screw feeder 40 back through a port 42 into chamber 18 of the reactor vessel 20. It is combusted to help maintain the reaction temperature.
  • Some ash is continuously removed, still hot, from the cyclone by a rotary valve 44 and fed by a screwfeeder 46 under a cooling water spray 48 to an ash bucket conveyor 50.
  • the conveyor dumps it into a chute 52 and thence into a glass storage silo 54.
  • the silo may be equipped with its own screwfeeder 56 for unloading and hauling away the ash.
  • This ash is largely powered silica and has only a fraction of the volume of the original biomass material, perhaps 20%.
  • the oil and gas from the cyclone 39 are shown piped out the top of the cyclone together by duct 59 and, although the oil may be condensed, it is simpler to leave it in the vapor phase mixed with the gas for burning.
  • the gas and/or oil may be utilized to generate steam for the dryer or electrical power to run any of the apparatus in the system.
  • This is shown in the system of FIG. 2 in the form of a conventional gas burner 58 used with a forced draft fan 60 and a boiler 62 to make steam.
  • the boiler 62 may be a standard "D" type water tube boiler designed to generate 150 pound-per-square inch (10.35 bar) saturated steam. Flue gases are discharged to the atmosphere through- a stack 64, and no emission control equipment is required due to low dust loading of the gases. Conventional boiler auxiliary systems may be used if desired.
