High purity carbon sorbent monoliths, particularly effective for the removal of trace-contaminants such as ammonia, formaldehyde, and methyl mercaptan from a gas flow, are fabricated by 3D-printing polymer monoliths, pre-oxidizing them in a flow of air at a temperature below the melting point of the polymer precursor, carbonizing them, and subsequently activating them to a weight loss of about 20 percent. The pre-oxidation step effectively prevents polymer-monolith swelling and melting during carbonization.

High purity carbon sorbent monoliths that are particularly effective for the adsorption and subsequent desorption of trace-contaminants, such as ammonia, are produced by 3D-printing polymer monoliths, carbonizing them, and subsequently activating them to produce an effective amount of at least one type of oxygen species on exposed carbon surfaces. The high purity carbon sorbent monoliths are vacuum-regenerable on a time scale of a few minutes.

A medical imaging system for detecting ionizing radiation. The system includes one or more pixilated imagers positioned to acquire patient image data and one or more position sensors positioned to acquire patient position data. Once the patient image data and patient position data are acquired, one or more processors operably connected to each of the one or more pixilated imagers and one or more position sensors calculate a three-dimensional mass distribution based on patient image data and patient position data.

Medical devices for diagnostic imaging

A sorbent that is particularly effective for the efficient adsorption and subsequent desorption of ammonia is produced from a high-purity carbon material which is exposed to an oxidizing environment so as to produce an effective amount of at least one oxygen species on its exposed surfaces. The high purity carbon material may be produced by carbonizing a polymer material, and the sorbent may comprise a support having an open-cell, three dimensional, lattice-like structure.

Carbon sorbent for reversible ammonia sorption

High-strength porous carbon and a method of its manufacture are described for multifunctional applications, such as ballistic protection, structural components, ultracapacitor electrodes, gas storage, and radiation shielding. The carbon is produced from a polymer precursor via carbonization, and optionally by surface activation and post-treatment.

High-strength porous carbon and its multifunctional applications

The method enables control over carbon pore structure to provide sorbents that are particularly advantageous for the adsorption of specific gases. It involves preparation of a sorbent precursor material, carbonization of the precursor material, and, usually, activation of the carbonized material. The resultant material is subjected to heat treatment and/or to surface conditioning by a reducing gas at elevated temperatures.

Carbon-based sorbent for gas storage, and method for preparation thereof

The method for generating a hydrogen-rich stream from hydrocarbon fuels, ultimately to produce hydrogen gas, involves the following two steps performed in a cyclic fashion: (1) pyrolysis of the hydrocarbon fuel to obtain a carbon-rich fraction and a hydrogen-rich fraction; and (2) oxidation of the carbon-rich fraction, or a portion of it, for heat generation. The method involves the following optional steps: (3) steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; (4) water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and (5) steam reforming of light hydrocarbons that may be produced in step (1) to produce more hydrogen and carbon monoxide.

Pyrolysis-based fuel processing method and apparatus

Solid waste resource recovery in space is effected by pyrolysis processing, to produce light gases as the main products (CH, H, CO, CO, HO, NH) and a reactive carbon-rich char as the main byproduct. Significant amounts of liquid products are formed under less severe pyrolysis conditions, and are cracked almost completely to gases as the temperature is raised. A primary pyrolysis model for the composite mixture is based on an existing model for whole biomass materials, and an artificial neural network models the changes in gas composition with the severity of pyrolysis conditions.

A method for producing high capacity gas-storage microporous sorbents involves precursor carbonization under relatively severe heat-treatment conditions, normally followed by activation using a cyclic chemisorption-desorption process.
