Abstract: A gas-liquid contacting apparatus and method are described, in which at least one rotor assembly including packing is arranged in a contacting chamber containing at least one stator assembly including at least one heat exchanger arranged to thermally modulate the gas-liquid contacting so that each stator assembly is operatively arranged with each stator assembly to provide gas-liquid contacting at temperatures effective for mass exchange between the gas and liquid. The rotor and stator assemblies may be of annular shape, or may be of disk shape in a stacked array of rotor assemblies alternating with stator assemblies. Such apparatus and method are usefully employed for CO2 capture from CO2-containing flue gases such as combustion effluents from power generation plants.

Abstract: Synthesis gas containing nitrogen as the majority component is processed to increase the hydrogen to carbon dioxide ratio. Nitrogen, carbon dioxide, and other contaminants are subsequently removed by a purification unit to produce a purified hydrogen gas stream. A recycle stream within the purification unit helps achieve a hydrogen purity greater than 99.9 percent, and hydrogen recovery greater than 99 percent.

Abstract: A carbon dioxide reduction reaction electrocatalyst comprises a pyrolyzed copper-based metal-organic framework (MOF) that produces isopropanol from electrochemical reduction of carbon dioxide. A process for producing isopropanol from electrochemical reduction of carbon dioxide comprises applying a potential in an electrochemical cell in the range of about −2V to about −3V versus a silver chloride electrode.
