Device and Method for Energy and Material Conversion Using Pyroelectric Materials for the Production of Fission Products

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a device and method for converting energy and substances using pyroelectric materials to split chemical compounds in fluids (gases or liquids), such as water or carbon dioxide, to produce products like hydrogen, oxygen, methane, or methanol. The system uses temperature cycles and pyroelectric effect – where certain materials generate strong electric fields in response to temperature fluctuations – to drive chemical cleavage reactions without the need for traditional electrodes or external electrical input. It is designed for efficient use of low-temperature waste heat, with continuous processing and advanced separation techniques to recover valuable reaction products.

Use CasesContent extracted from patent full text and abstract with AI.

• Hydrogen production from water splitting using industrial waste heat.
• Conversion of carbon dioxide into valuable products such as carbon monoxide, methane, or methanol, aiding carbon capture and utilization strategies.
• Integration into power-to-gas or power-to-liquid technologies for energy storage (for example, converting excess renewable electricity into storable fuel).
• Recovery and valorization of low-grade waste heat in chemical, steel, or power plants by turning it into chemical feedstocks.
• On-site fuel generation in facilities producing high-temperature exhaust gases (data centers, bakeries, breweries, etc.).

BenefitsContent extracted from patent full text and abstract with AI.

• Enables efficient utilization of low-grade/waste heat sources that are otherwise difficult to exploit.
• Produces valuable chemicals (like hydrogen, methane, and methanol) from abundant resources such as water and CO₂ without direct electrical input.
• Potential to enhance overall process efficiency and energy savings in industrial operations.
• Continuous process design with improved heat and mass transfer, leading to higher product yields and operational efficiency compared to batch electrolytic or thermochemical processes.
• Flexible, scalable system adaptable to different feedstocks and waste heat sources.
• Reduced maintenance needs and easier material replacement due to modular and robust design.

Patent Abstract

The invention relates to a device and to a method for energy and substance conversion by means of pyroelectric materials for producing cleavage products from fluids, wherein the device (1) comprises at least two pyroelectric converters (20, 22) which are connected to one another in relation to a controlled valve device (8) and each have a drain line (11, 23); at least one line (14) associated with the first pyroelectric converter (20) for discharge of cleavage products (48, 52); at least one line (24) associated with the second pyroelectric converter (22) for discharge of cleavage products (52, 48), wherein a pyroelectric converter (20) contains at least a heat exchanger (2), which is connected to a supply line (7) to which the valve device (8) is assigned for delivering at least one fluid stream (9) having a high temperature TH and at least one fluid stream (10) having a temperature TK lower than the temperature TH, wherein the heat exchanger has at least one drain line (11) connected to the supply line (7) and through which heat exchanger a heat-absorbing fluid (50) flows which is to be cleaved; at least one reactor (3) for cleavage of the fluid (50) into cleavage products (48), wherein the reactor (3) has at least one pyroelectric material (12) having a predetermined Curie temperature TC; an apparatus (5), out of which at least the line (14) is led for discharge of at least one cleavage product (48) produced in the reactor (3); a controlled circulation pump (6), which is disposed within a circuit (15) with the heat exchanger (2), reactor (3), and apparatus (5) which belong to the circuit (15) and are connected to one another, and which supplies flowing fluid (50) to be cleaved to the circuit (15) via a line system (16) connecting the circuit (15), the circulation pump (6) being connected to the controlled valve device (8) externally via a control unit (18). The device (1) comprises at least one separation unit (43) associated with the pyroelectric converter (20, 22) for defined separation of the final cleavage products (48, 52) discharged from the apparatus (5) disposed downstream of the respective reactor (3), and the lines (14, 24) for controlled discharge of the cleavage products (48, 52) open into the separation unit (43), from which at least lines (25, 26) for discharging definitely separated final cleavage products (48, 52) extend.
