A biomass-derived thermosetting polymer material being a product of processing a biomass feed material via a twin screw extruder having a length extending between an inlet and an outlet. Hot water from a water heater is injected into at least one inlet along the length of the twin screw extruder, the at least one inlet generally corresponding with a pressure boundary within the twin screw extruder. A pressure-sustaining valve is connected between the length of the twin screw extruder and the outlet, with the valve being adjusted to produce the biomass-derived thermosetting polymer material.


Aspects of the invention are associated with the discovery of processes for converting methane (CH_(4)), present in a methane-containing feedstock that may be obtained from a variety of sources such as natural gas, to higher hydrocarbons (e.g., C_(4)^(+) hydrocarbons) such as gasoline, diesel fuel, or jet fuel boiling-range hydrocarbons, which may optionally be separated (e.g., by fractionation) for use as transportation fuels, or otherwise as blending components for such fuels. Particular aspects of the invention are associated with advantages arising from maintaining reaction conditions that improve the yield of C_(4)^(+) hydrocarbons. Further aspects relate to the advantages gained by integration of the appropriate reactions to carry out the methane conversion, with downstream separation to recover and recycle desirable components of the reaction effluent, thereby improving process economics to the extent needed for commercial viability.

Hydropyrolysis processes that accompany the generation of activated carbon as an end product, as well as processes for the production of activated carbon from hydropyrolysis char, are described. Representative processes comprise upgrading, by steam activation, char that is formed from solid biomass-containing feedstocks and/or solid biomass derived feedstocks, such as lignocellulosic feedstocks (e.g., wood). Such processes are associated with a number of advantages in terms of achieving operating synergies, obtaining desirable intermediate material and end product properties, reducing environmental impact, and significantly improving economic attractiveness.

Various techniques are disclosed for pretreating municipal solid waste (MSW) and other biomass-containing feedstocks that may be of a poorer quality and consequently more difficult, or even impossible, to convert to higher value liquid products (e.g., transportation fuels) using conventional processes. Such conventional processes may otherwise be satisfactory for the conversion of the biomass portion of the feedstock alone. The pretreatment of biomass-containing feedstocks may generally include steps carried out prior to a hydropyrolysis step and optionally further steps, in order to change one or more characteristics of the feedstock, rendering it more easily upgradable.

A radiant, non-catalytic recuperative reformer has a flue gas flow path for conducting hot exhaust gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is positioned adjacent to the flue gas flow path to permit heat transfer from the hot exhaust gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, a portion of the reforming mixture flow path is positioned outside of flue gas flow path for a relatively large residence time.

A method and software-implemented system that provides a situational awareness tool for infrastructure operators and government agencies to assess vulnerabilities, and optimize the deployment of prevention and mitigation technologies. The invention automatically obtains current supply information from each of more than one participating utility provider. The supply information from the different sources is standardized and combined with geographic information to provide a building level map of utility service and outages. The service locations, e.g., residential and commercial buildings, are represented as building polygons corresponding to building footprint, and can be color-coded to indicate service status.


This invention relates to a process for thermochemically transforming biomass or other oxygenated feedstocks into high quality liquid hydrocarbon fuels. In particular, a catalytic hydropyrolysis reactor, containing a deep bed of fluidized catalyst particles is utilized to accept particles of biomass or other oxygenated feedstocks that are significantly smaller than the particles of catalyst in the fluidized bed. The reactor features an insert or other structure disposed within the reactor vessel that inhibits slugging of the bed and thereby minimizes attrition of the catalyst. Within the bed, the biomass feedstock is converted into a vapor-phase product, containing hydrocarbon molecules and other process vapors, and an entrained solid char product, which is separated from the vapor stream after the vapor stream has been exhausted from the top of the reactor. When the product vapor stream is cooled to ambient temperatures, a significant proportion of the hydrocarbons in the product vapor stream can be recovered as a liquid stream of hydrophobic hydrocarbons, with properties consistent with those of gasoline, kerosene, and diesel fuel. Separate streams of gasoline, kerosene, and diesel fuel may also be obtained, either via selective condensation of each type of fuel, or via later distillation of the combined hydrocarbon liquid.

A hydropyrolysis process comprises feeding both (i) hydrogen and (ii) a biomasscontaining feedstock or a biomass-derived feedstock, to a hydropyrolysis reactor vessel. The process comprises producing a CO2-containing vapor stream and at least one liquid product. A CO2 product, separated from the CO2-containing vapor stream, is advantageously used for at least one inertization function of the hydropyrolysis process. Representative inertization functions include operation of solids transport equipment, blanketing of liquid containers, drying of biomass-containing feedstock or biomass-derived feedstock, conveying or separating solids, and combinations thereof. Importantly, CO2 products utilized for these inertization functions may be obtained predominantly, if not completely (depending on the nature of the feedstock), from renewable carbon in biomass.

Processes and systems for producing hydrogen gas utilizing a sorbent enhanced reformer in combination with a calciner operating at atmospheric pressure. Feed material is introduced into the sorbent enhanced reformer to produce carbon dioxide and hydrogen gas. Sorbent material within the reformer acts to absorb carbon dioxide and form a used sorbent. The used sorbent is introduced into the atmospheric calciner to heat the used sorbent to desorb carbon dioxide from the used sorbent to produce regenerated sorbent which can be recycled to the reformer.

A reactor system includes a fluidized-bed. A fuel and a sulfur absorbent material are eluted through the fluidized-bed. The reactor system may include a heat exchanger having a heat-exchanging portion within a heating zone of the reactor that is hermetically sealed from the heating zone. The reactor may include loose particles of an inert bed material for forming the fluidized-bed. A feed system may be provided to inject a solid fuel composite that includes a mixture of a solid, carbonaceous fuel and a solid reagent into the reactor.
