20100040510 | METHOD FOR CONVERTING BIOMASS INTO SYNTHESIS GAS USING A PRESSURIZED MULTI-STAGE PROGRESSIVELY EXPANDING FLUIDIZED BED GASIFIER FOLLOWED BY AN OXYBLOWN AUTOTHERMAL REFORMER TO REDUCE METHANE AND TARS - The invention provides systems and methods for converting biomass into syngas using a pressurized multi-stage progressively expanding fluidized bed gasifier to eliminate or reduce the formation of methane, volatiles such as BTX, and tars. The gasifier may include a reactive stage that may receive a biomass feed through a feed line and oxygen through an oxygen feed line. The gasifier may also include a fluidized bed section that may be configured to receive the reaction products from the first stage, mix them and perform fluidized bed activity. A gasifier may also have a disengagement section that may be configured to separate fluidized media and particulate matter from syngas product. A gasification system may also include oxyblown catalytic autothermal reactor and a cryogenic air separation unit. | 02-18-2010 |
20100040527 | PROCESS FOR PRODUCING AMMONIA FROM BIOMASS - This invention provides a process for making ammonia from biomass. The biomass may be first reacted with oxygen and steam to generate a biosyngas comprising hydrogen (H | 02-18-2010 |
20100108523 | Removal of Glycerin from Biodiesel Using an Electrostatic Process - A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel. | 05-06-2010 |
20130030063 | PROCESS AND METHOD FOR THE PRODUCTON OF DIMETHYLETHER (DME) - Disclosed herein is a process for the production of fuel grade DME from carbonaceous fuels, including a pressurized multi-stage progressively expanding fluidized bed gasifier and an oxyblown autothermal reformer to produce a synthesis gas (syngas) with desirable hydrogen to carbon monoxide molar ratio, which then undergoes gas-phase DME one-step direct synthesis in a fluid pluralized bed reactor over an attrition resistant bifunctional catalyst. The crude DME thus obtained is purified in a two column distillation unit to produce a fuel grade DME having a purity greater than 99.98 mole %. | 01-31-2013 |
20130035406 | SYNTHESIS OF DME USING A FLUID PLURALIZED BED REACTOR - This invention discloses a method for making a dimethylether (DME) product from a synthesis gas (syngas) in the presence of a catalyst in a fluid pluralized bed reactor operating in the gas phase. The reactions generate a significant amount of heat and the heat management is balanced between supplying quench recycle syngas to the pluralized sections along the reactor and also by controlling the preheat temperature of the reactant streams. Gas phase fluidization of the catalyst is controlled so that the pluralized reactive zones are maintained in a backmix configuration. | 02-07-2013 |

20130197249 | EXTRACTION OF IMMOBILIZED OIL USING MIXTURES OF FOOD GRADE SOLVENTS - The invention provides extraction of immobilized oil from an oil-containing feed using a food grade solvent. The food grade solvent may include ethyl acetate or ethyl lactate. The solvent may also include an ethanol co-solvent with the ethyl acetate or ethyl lactate. The solvent may be recaptured within the system and reused in the process. | 08-01-2013 |

20140364654 | DIMETHYL ETHER (DME) PRODUCTION PROCESS - Disclosed herein is a process for monetization of natural gas by producing fuel grade dimethyl ether (DME). The process includes three reactive stages with the first reactive stage being the conversion of natural gas into syngas, the second reactive stage being the conversion of syngas into crude methanol and the third reactive stage being the production of fuel grade dimethyl ether. The management and optimization of the water and steam circuits is important to maintain net overall system efficiency and mitigation of any liquid effluents. | 12-11-2014 |
