  • Patent number: 9382558
    Abstract: This invention relates to a new process for making fatty acids directly from a feedstock consisting of phytoplankton in water without the need to a) thermally separate, dewater and dry the phytoplankton, and b) extract the immobilized lipids. Our method is much less expensive than the current practice of making fatty acids from phytoplankton, because we bypass the costly and energy intensive operations associated with a) dewatering and drying the biomass, and b) extracting the immobilized lipids. As such, this invention greatly enhances the economic viability of making biofuels and bioproducts from phytoplankton.

  • Publication number: 20140364654
    Abstract: 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.

  • Patent number: 8791165
    Abstract: 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.

  • Patent number: 8546454
    Abstract: 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 %.

  • Publication number: 20070003644
    Abstract: A process for preparing a concentrated polyphenolic product is disclosed. The process generally includes the extraction of polyphenolic compounds from grape material using a solvent containing ethanol and water, and further includes steps of extract filtration and extract concentration to provide either a liquid polyphenolic concentrate or a powdered polyphenolic extract. The concentrated polyphenolic product may be used in food products and dietary supplements to afford the health benefits of consuming red wine. An additional process for preparing a concentrated ethanol product with a prefermentation step in addition to a concentrated polyphenolic product also is disclosed.

  • Patent number: 6984372
    Abstract: This invention relates to a sulfur tolerant, dynamic, compact, lightweight fuel process and system that is capable of converting sulfur bearing carbonaceous fuels to hydrogen rich gases suitable for fuel cells or chemical processing applications. The process and system is based on the AHR and WGS reactions, followed by cleanup of byproduct sulfur-containing gases and carbon oxides that would otherwise poison the fuel cell electrocatalyst. Advantageously, this is accomplished via an ASMS and a methanator or an AWMR. The process and system preferably uses a special sulfur tolerant catalysts and hardware designs that enable the conversion in an energy efficient manner while maintaining desirable performance characteristics such as rapid start-stop and fast response to load change capabilities.

  • Patent number: 6904461
    Abstract: A method and apparatus determines an inbound traffic intensity of a visitable site, wherein the inbound traffic intensity factor is representative of a measure of meaningful visits to a visitable site in a given time period. The inbound traffic intensity factor is determined by obtaining visitor information including the number of visits to the visitable site during the given time period as well as the duration of each visit and using both the number visits and the time spent during each visit to quantify the traffic to the site during the time period.
