Resumen de: US2025346542A1

Embodiments of the present invention relates to two improved catalysts and associated processes that directly converts carbon dioxide and hydrogen to liquid fuels. The catalytic converter is comprised of two catalysts in series that are operated at the same pressures to directly produce synthetic liquid fuels or synthetic natural gas. The carbon conversion efficiency for CO2 to liquid fuels is greater than 45%. The fuel is distilled into a premium diesel fuels (approximately 70 volume %) and naphtha (approximately 30 volume %) which are used directly as “drop-in” fuels without requiring any further processing. Any light hydrocarbons that are present with the carbon dioxide are also converted directly to fuels. This process is directly, applicable to the conversion of CO2 collected from ethanol plants, cement plants, power plants, biogas, carbon dioxide/hydrocarbon mixtures from secondary oil recovery, and other carbon dioxide/hydrocarbon streams. The catalyst system is durable, efficient and maintains a relatively constant level of fuel productivity over long periods of time without requiring re-activation or replacement.

Resumen de: AU2025202787A1

Abstract The invention relates to the coating of anion exchange membranes (AEM) with catalytically active substances. The CCM thus obtained are used in electrochemical cells, especially for alkaline water electrolysis.

COATING OF ANION EXCHANGE MEMBRANES

Resumen de: AU2024245553A1

The invention relates to the coating of anion exchange membranes with catalytically active substances. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The problem addressed by the invention is that of specifying a process for coating an anion exchange membrane which can be conducted at relatively low temperatures. This problem is solved by a swelling step. Aside from the swelling step and the processing temperature, the sequence of the process according to the invention resembles a decal process. However, the use of the partly liquid swelling agent means that the process according to the invention can be considered to be a wet process. The process enables the processing of anion-conducting polymers at moderate temperatures. The anion-conducting polymers may be present in the anion exchange membrane and/or in the composition that is applied to the anion exchange membrane. The advantage of the process according to the invention is that it can be conducted at comparatively low temperatures, namely below 100°C.
