A mixing apparatus for producing a feedstock for a reformer, the mixing apparatus including at least one mixing vessel comprising a cylindrical vessel with a conical bottom; a steam inlet configured for introducing steam into the conical bottom; a carbonaceous material inlet configured for introducing a carbonaceous feed into the cylindrical vessel; and an outlet for a reformer feedstock comprising at least 0.3 pounds of steam per pound of carbonaceous material, with the at least one mixing vessel configured for operation at a pressure of greater than about 10 psig.

Biomass high efficiency hydrothermal reformer

A system including a mixing apparatus configured to produce a reformer feedstock and comprising one or more cylindrical vessel having a conical bottom section, an inlet for superheated steam within the conical bottom section and an inlet for at least one carbonaceous material at or near the top of the cylindrical vessel, wherein the one or more cylindrical vessel is a pressure vessel configured for operation at a pressure in the range of from about 5 psig (34.5 kPa) to about 50 psig (344.7 kPa); a reformer configured to produce, from the reformer feedstock, a reformer product comprising synthesis gas, and also producing a hot flue gas; a synthesis gas conversion apparatus configured to catalytically convert at least a portion of the synthesis gas in the reformer product into synthesis gas conversion product, and to separate, from the synthesis gas conversion product, a spent catalyst stream and a tailgas.

Integrated biorefinery for production of liquid fuels

A system for the production of synthesis gas, the system including a mixing apparatus configured for combining steam with at least one carbonaceous material to produce a reformer feedstock; and a reformer comprising a cylindrical vessel containing a plurality of coiled tubes, wherein each of the plurality of coiled tubes has a vertical height in the range of from about 40 feet 12.2 m) to about 100 feet (30.5 m) and a coil length that is at least four times the vertical height; at least one burner configured to combust a fuel and provide heat to maintain the reformer at a reformer temperature; at least one outlet for reformer product comprising synthesis gas; and at least one outlet for flue gas produced via combustion of fuel in the burners. A suitable mixing apparatus is also provided.

A system for the production of conversion products from synthesis gas, the system including a mixing apparatus configured for mixing steam with at least one carbonaceous material to produce a reformer feedstock; a reformer configured to produce, from the reformer feedstock, a reformer product comprising synthesis gas comprising hydrogen and carbon monoxide from the reformer feedstock; a synthesis gas conversion apparatus configured to catalytically convert at least a portion of the synthesis gas in the reformer product into synthesis gas conversion product and to separate from the synthesis gas conversion product a tailgas comprising at least one gas selected from the group consisting of carbon monoxide, carbon dioxide, hydrogen and methane; and one or more recycle lines fluidly connecting the synthesis gas conversion apparatus with the mixing apparatus, the reformer, or both.

A method of producing synthesis gas by mixing a carbonaceous feed comprising at least one carbonaceous material with superheated steam to produce a reformer feedstock and reforming the reformer feedstock to produce a first synthesis gas comprising hydrogen and carbon monoxide by introducing the reformer feedstock into a plurality of coiled tubes within a reformer at a reformer temperature and a reformer pressure at which at least a portion of the reformer feedstock is converted to synthesis gas.

A method and system for reforming a carbonaceous feedstock comprising the steps, reforming the feedstock produce a first synthesis gas, subjecting a portion of the first synthesis gas to catalytic conversion, separating from the synthesis gas conversion product at least one byproduct, and utilizing at least a portion of the at least one byproduct during reforming of additional carbonaceous material. In certain instances, the method and system may be used to produce a liquid fuel.
