  • Patent number: 9068121
    Abstract: A process for pyrolyzing biomass comprises pyrolyzing cellulosic biomass in a fast pyrolysis chamber by heating the cellulosic biomass to a pyrolyzation temperature to generate a pyrolysis vapor flow therefrom. The pyrolysis vapor flow is directed from the fast pyrolysis chamber along a vapor flow conduit to a condensation trap at a temperature sufficient to condense the vapor to liquid and generate a thermal gradient along the vapor flow conduit between the pyrolysis chamber and condensation trap. A majority of the pyrolysis vapor flow along the vapor flow conduit to the condensation trap is achieved by natural convection. Systems that can practice this process are also disclosed.

    Abstract: The present invention relates to a process and system for gasifying biomass or other carbonaceous feedstocks in an indirectly heated gasifier and provides a method for the elimination of condensable organic materials (tars) from the resulting product gas with an integrated tar removal step. More specifically, this tar removal step utilizes the circulating heat carrier to crack the organics and produce additional product gas. As a benefit of the above process, and because the heat carrier circulates through alternating steam and oxidizing zones in the process, deactivation of the cracking reactions is eliminated.

    Abstract: A biofuel gasification reactor for producing gases that are combustible in an internal combustion engine. The reactor includes a vessel with a loading port and cover, sized to receive biofuel of at least eight by twenty inches. A storage zone provides biofuel via gravity feed only to a plasma zone that oxidizes the biofuel into char and precursor gases. Air nozzles provide air to the plasma zone from a helical air preheater. A char zone receives the precursor gases and char. The precursor gases are substantially converted to effluent gases of hydrogen and carbon monoxide. A grating below the char zone holds the char until it is oxidized to ash. The grating covers the entire bottom of the char zone. The grating is disposed in a substantially fixed and immovable configuration during the operation of the reactor.

  • Patent number: 8377155
    Abstract: The auger gasifier described includes, in its preferred embodiments, a vertically elongated (“oblong”) primary gasifier chamber with an auger that can move up and down, allowing for large amounts of fuel input when necessary. This improvement, in turn, requires and/or is facilitated by provision for simultaneous elevation adjustments of the auger and bed dam to assure that fuel material is processed in degrees from the top downward without sweeping massive amounts of the fluidized bed materials towards the output end of the chamber. Another improvement involves provision for pressurization of the primary gasifier chamber, allowing substantial improvements in the speed of processing materials through the gasifier. Due to issues arising from thermal expansion of the refractory material lining the chamber, provision is made for nozzle and refractory imbedded pipe hole thermal expansion capability.

  • Publication number: 20130019529
    Abstract: A method for producing synthesis gas, including: 1) pre-processing a biomass raw material; 2) pyrolyzing the biomass raw material to yield a pyrolysis gas and a carbon powder; 3) separating the pyrolysis gas from the carbon powder and a solid heat carrier; 4) separating the carbon powder away from the solid heat carrier via a solid-solid separator; 5) conveying the generated pyrolysis gas to a condensate tank for spray condensation, condensing a condensable part in the pyrolysis gas to generate biological fuel oil, pressurizing the generated biological fuel oil by a high pressure oil pump and feeding to a gasification furnace to be gasified; and 6) feeding one part of non-condensable pyrolysis gas to a combustion bed to combust with air, and conveying the other part of the non-condensable pyrolysis gas to the pyrolysis bed as a fluidizing medium.

  • 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.

  • Patent number: 8202332
    Abstract: Methods for fractional catalytic pyrolysis which allow for conversion of biomass into a slate of desired products without the need for post-pyrolysis separation are described. The methods involve use of a fluid catalytic bed which is maintained at a suitable pyrolysis temperature. Biomass is added to the catalytic bed, preferably while entrained in a non-reactive gas such as nitrogen, causing the biomass to become pyrolyzed and forming the desired products in vapor and gas forms, allowing the desired products to be easily separated.

  • Patent number: 8118894
    Abstract: An energy efficient process for converting biomass into a higher carbon content, high energy density slurry. Water and biomass are mixed at a temperature and under a pressure that are much lower than in prior processes, but under a non-oxidative gas, which enables a stable slurry to be obtained containing up to 60% solids by weight, 20-40% carbon by weight, in the slurry. The temperature is nominally about 200° C. under non-oxidative gas pressure of about 150 psi, conditions that are substantially less stringent than those required by the prior art. In another embodiment, the biomass water slurry can be mixed with a coal water slurry to further optimize the carbon content and pumpability of the biomass slurry.

  • Patent number: 8088188
    Abstract: A system and process for gasifying carbonaceous feedstock with staged slurry addition in order to prevent the formation of tar that causes deposition problems. Dry solid carbonaceous material is partially combusted, then pyrolyzed along with a first slurry stream comprising carbonaceous material in two separate reactor sections, thereby producing mixture products comprising synthesis gas. The second slurry stream comprising particulate carbonaceous material is fed to a drying unit downstream of a heat recovery zone along with the mixture product exiting the heat recovery zone The resulting final temperature of the second stage mixture products and dried particulate carbonaceous material is between 450° F. and 550° F., a temperature range that is typically not conducive to the emission of heavy molecular-weight tar species.
