  • Patent number: 10023807
    Abstract: A method for treatment of a carbonaceous feedstock such as coal or biomass. The method comprises adsorbing an oxidizing agent selected from an oxygen-containing gas, hydrogen peroxide, ozone and oxidizing acids from a liquid phase of an aqueous mixture comprising water and the carbonaceous feedstock onto the carbonaceous feedstock to produce an aqueous mixture with the liquid phase having a reduced content of the oxidizing agent and the carbonaceous feedstock having oxidizing agent adsorbed on a surface thereof, and heating this aqueous mixture to a temperature and for a sufficient time to partially oxidize and solubilize at least a portion of the carbonaceous feedstock. The reaction products may be chemically or physically separated, recycled to the heating step and/or subjected to microbial digestion in order to generate one or more desirable products from the carbonaceous feedstock. The solid portion of the reaction products may be further processed to be used in the paper industry.

  • Patent number: 9701600
    Abstract: During the production of methanol from inert-rich syngas, a catalytic pre-reactor is installed upstream of the single- or multi-stage synthesis loop, a first part of the syngas being converted to methanol in the catalytic pre-reactor. An inert gas separation stage, for example a pressure swing adsorption system or a membrane system, can be connected downstream of the synthesis loop, whereby a hydrogen-enriched syngas stream can be returned to the synthesis loop. In the processing of methane-rich syngas, the inert gas separation stage may also have an autothermal reformer in which methane is converted to carbon oxides and hydrogen, which are also returned into the synthesis loop.

  • Publication number: 20150025266
    Abstract: In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.

  • Patent number: 8927781
    Abstract: A method for producing ethanol by which ethanol can be synthesized from less fermentable biomass materials such as plant-derived materials and rice straws and industrial waste biomass materials such as wooden building materials and pulp and which can therefore broaden the range of raw materials for the production of ethanol. Specifically, a method for producing ethanol including reacting a raw material gas obtained by a thermochemical gasification reaction of biomass in the presence of a catalyst containing rhodium, at least one transition metal, and at least one element selected from lithium, magnesium and zinc.

  • Patent number: 8921431
    Abstract: Mixed alcohols are produced from syngas. The syngas is provided to a catalyst in a reactor at selected temperatures and pressures. Reactive products, including mixed alcohols, are removed from the reactor. Non-reactive components are removed from the mixed alcohols of their reaction products. At least part of the non-reactive components are reintroduced in the reactor along with syngas. The non-reactive components are a solvent or a supercritical fluid. The nonreactive components can be reintroduced into the reactor with reactive components such as methanol or CO2.

  • Publication number: 20140323694
    Abstract: PFRs for running multiphasic processes are disclosed. The PFRs are single or multi-chamber devices having at least three types of regions (a liquid-contacting region, a gas-contacting region and a liquid-collection region), and a porous substrate providing fluid communication at least between the liquid-contacting and gas-contacting regions. Removal of liquid from the porous substrate, such as by collecting the liquid as it flows off the bottom of the porous substrate in the liquid-collection region or such as by evaporation of the liquid from the porous substrate in the evaporation region supports a continuous flow process. Methods of using the PFRs are also disclosed, for example methods of using the PFRs as photobioreactors for cultivating photosynthetic microorganisms, for producing fermentable sugars, for producing ethanol, for fermenting synthesis gas and producing single cell protein from natural gas.
