Embodiment Construction

[0017] The first embodiment relates to a sorbent structure, which includes a continuous activated carbon body in the form of a flow-through substrate; and an additive provided on the flow-through substrate, which can promote CO 2 Sorption on the structure of the sorbent.

[0018] The term "continuous activated carbon body" means that the carbon has a continuous uninterrupted structure, rather than agglomerates of discontinuous carbon particles held together by a binder. As will be discussed further below, in addition to continuous activated carbon, such a body may also include any suitable filler materials, such as inorganic or organic materials, or even particulate carbon. The continuous activated carbon main sorbent structure can be obtained in the following manner, for example, by carbonization to convert a carbon-containing synthetic polymer material into a continuous carbon structure, and then activate the continuous carbon structure.

Abstract

A sorbent structure comprising a continuous activated carbon body in the form of a flow-through substrate; and an additive provided on the flow-through substrate, wherein the additive is capable of enhancing the sorption of CO2 on the sorbent structure. Methods of making the sorbent structure, its use for CO2 capture, and methods for regenerating the structure for further use.

Description

Invention field [0001] The invention relates to a sorbent structure, such as a honeycomb body, that can be used to remove carbon dioxide from gases. Background technique [0002] As we all know, carbon dioxide (CO 2 ) Is closely related to global warming, and global warming will increase the probability of natural disasters such as storms and floods. Power plants contribute all CO related to human activities 2 One third of the emissions, each power plant can emit millions of tons of CO 2 . In addition, in other industries, such as petroleum refining, cement industry, and steel production industry, each factory also emits a large amount of CO 2 . We should capture and store CO 2 , To significantly reduce emissions without significant changes to the basic process, [0003] There are many ways to reduce CO 2 Emissions, for example, by improving the efficiency of power plants or by converting coal into natural gas. However, these methods alone cannot achieve the required CO 2 Emissi...
