Carbon dioxide-based strong active energy-gathering agent and its preparation method and application

Abstract

The invention belongs to the field of new energy power development and utilization, and particularly relates to a carbon dioxide based high-activity energy gathering agent and a preparation method thereof. The carbon dioxide based high-activity energy gathering agent is prepared from high-activity metallic powder, a high-energy oxidizer, explosion imitating agent particles and inert gas through mixing, and a mass ratio of the high-activity metallic powder to the high-energy oxidizer to the detonation imitating agent particles to the inert gas is 12:(0-3):(0-1):(1-2); the metallic powder is one or more of metallic sodium powder, metallic magnesium powder, metallic potassium powder and metallic aluminum powder; the particle size of the metallic powder is one or more of nanometer level, micrometer level and millimeter level. The carbon dioxide based high-activity energy gathering agent and carbon dioxide in a mass ratio being 1:(1-2) are mixed and subjected to a redox reaction, instantaneous carbon dioxide explosion shock waves and phase change shock waves are produced, and a high-temperature and high-pressure power source is formed, can supply strong power to the fields of buildings, civil engineering, machinery, automobiles, aviation, ships, ocean and the like and is a novel green power source.

Description

technical field [0001] The invention belongs to the field of new energy power development and utilization, and in particular relates to a carbon dioxide-based highly active energy-gathering agent and its preparation method and application. Background technique [0002] A series of studies by the Intergovernmental Panel on Climate Change (IPCC) pointed out that global climate change is an undoubted fact, and massive emissions of greenhouse gases are one of the main factors affecting global warming. Carbon dioxide capture, storage and utilization technology (CCS or CCUS) has become one of the key technologies for reducing carbon dioxide emissions in the world. As the main component of greenhouse gases, carbon dioxide has become the focus of international governments. Strengthening the capture and utilization of carbon dioxide has become a consensus at home and abroad. Projects such as carbon dioxide flooding, carbon dioxide flooding, carbon dioxide flooding coalbed methane, ...

Problems solved by technology

More importantly, as a local device, the heater can only be located in the local space of carbon dioxide, and the energy radiation and convection generated will take time, resulting in the inability to precisely control the time of the carbon dioxide phase transition explosion. For fields that require precise control of the detonation time, has obvious limitations
