Abstract

The invention belongs to the field of environment-friendly materials, and particularly relates to microporous granular carbon and a preparation method thereof. The technical problem to be solved by the invention is to provide microporous granular carbon and the preparation method thereof. The preparation method comprises the following steps: A, emulsifying a chitosan solution or a polyvinyl alcohol solution, an oil-in-water emulsifier and an organic solvent to obtain an internal phase solution; mixing a water-in-oil emulsifier and an organic solvent to obtain an external phase solution; mixinga cross-linking agent and the external phase solution to obtain a curing bath; B, respectively injecting the internal phase solution and the external phase solution into an injection tube and a collection tube of a capillary micro-fluidic chip to form a monodisperse water-oil emulsion, and injecting the monodisperse water-oil emulsion into the curing bath to be subjected to a cross-linking reaction with the cross-linking agent to obtain particles; and C, washing, drying and carbonizing the particles to obtain the microporous granular carbon. The method can be used for obtaining the microporous granular carbon, and is simple, easy to operate and pollution-free.

Description

technical field

[0001] The invention belongs to the field of environmental protection materials, and in particular relates to a microporous granular carbon and a preparation method thereof. Background technique

[0002] Over the past few decades, excess greenhouse gases in the atmosphere have led to significant global climate change. According to the government's Panel on Climate Change (IPCC), fumes from industry account for the global CO2 produced by fuels. 2 36% of emissions. Among the various CO2 removal technologies, post-combustion capture is the most applicable to the power industry. CO 2 Post-combustion capture technologies include adsorption, membrane separation, and absorption. Among them, the adsorption method is the most widely used due to its simple operation and regeneration process and low cost. Among many adsorbents, porous carbon is usually 2 The heat of adsorption is lower than 25kJ / mol, which can realize super energy saving in multiple adsorption-des...
