Description

technical field [0001] The invention relates to the technical field of carbon dioxide conversion and capture, in particular to a cogeneration device and method based on carbon dioxide conversion and utilization. Background technique [0002] Peak Carbon Carbon neutrality has given rise to a number of related technological solutions, including a variety of ways to capture carbon dioxide and storage devices. Reducing the future negative impact of carbon dioxide emissions on the earth is crucial, and an important part of this may involve finding the carbon dioxide emissions point. Methods of capturing carbon dioxide. Methods currently being developed include filtering the gas through adsorbent materials such as magnetic sponges, bubble membranes, zeolite foam or materials made from clay or coffee grounds. Many carbon capture methods are to store it as gaseous carbon dioxide, which can greatly increase its cost to store and transport, and can easily leak back into the air, caus...

Problems solved by technology

Much carbon is captured by storing it as gaseous carbon dioxide, which is significantly more expensive to store and transport, and can easily leak back into the air, contributing to the greenhouse effect

[0003] In order to efficiently solve the problem of carbon neutralization of carbon peaks, it is necessary to jointly produce carbon sheets or graphene in thermal power plants at the source of carbon dioxide generation, so as not to dispose of the carbon dioxide gas produced by them is difficult or costly. Based on this, research and development are urgently needed A cogeneration device and method based on the conversion and utilization of carbon dioxide is developed to solve the technical problems of high carbon capture costs and waste of resources caused by cogeneration in the prior art
