Abstract 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 C02 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 C02 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.

Disclosed in the present application are a catalyst, and a preparation method therefor and the use thereof. By using a chromium-manganese co-doped ruthenium-based catalyst, in cooperation with a coordination dispersion effect of a chelating agent structure, the catalyst provided in the present application effectively inhibits sintering agglomeration of chromium, manganese and ruthenium components, and the prepared catalyst has better uniformity. Chromium and manganese regulate and control a d electron center of a ruthenium active site at the same time and serve as a high-corrosion resistance protective layer, such that when an OER reaction is carried out under a strong-acidity electrolyte system, the catalyst can effectively maintain high-activity characteristics thereof, long-cycle stable operation is achieved, and the use cycle can reach 2000 hours. The catalyst serving as a high-performance acidic oxygen evolution reaction electrocatalyst can be used for stably and efficiently carrying out an oxygen evolution reaction (OER) in an acidic electrolyte environment, and can be used as an anode material for water electrolysis hydrogen production in a proton conduction polymer electrolysis hydrogen production electrolytic tank, thereby solving the problems of few types, low performance and a short service life of existing acidic oxygen evolution catalysts.

The invention relates to the combination of a dry cell and a flooded (wet) cell in a single cell, wherein stainless steel or metal strips (10) used in electrochemical analysis are arranged horizontally and circular openings are made in a geometrically balanced manner such that electricity is evenly distributed within the cell, allowing hydroxy gas to escape from the openings instead of getting caught between the stainless steel or metal strips (10). The stainless steel or metal strips (10) are connected directly to a thermal acrylic cylinder (3) without connectors or tubes, preventing the hydroxy gas, and even the electrolyte solution, from being carried to the stainless steel strips, as the thermal acrylic cylinder (3) is positioned on top of the stainless steel or metal strips (10). An effective result of this distinctive new design is that the device is smaller, enabling installation in small vehicles. In addition, the distinctive design makes the device easy to install and maintain, since the base of the device is only 7 x 7 cm, which facilitates installation in motors, vehicles and generators that use petroleum hydrocarbons as fuel, in addition to significantly reducing the production cost of this type of device.
