Description
Technical Field
The invention relates to a chemical reaction container, in particular to a flow channel membrane reactor.
Background
Small molecule alcohols, especially methanol, ethanol and n-propanol, play a crucial role in the modern chemical industry. To date, the production of small molecule alcohols has relied largely on fossil and biomass carbon source conversion. Under the existing process conditions, the process is often accompanied by obvious negative environmental friendliness, poor atom economy and high energy consumption. For example, the primary route of ethanol production in China is the biomass fermentation process.
Electrochemical carbon dioxide reduction (ECR) technology driven by renewable electricity is an effective means to achieve the above objectives, enabling the generation of high value-added products and an indication that net carbon dioxide emissions are zero.
The industrial application of electrocatalysis carbon dioxide reduction is the future development trend in the field, and can make up for and gradually replace the traditional technology for preparing micromolecule alcohols in the industry at present. The following four difficulties still exist in the process of the technical transformation:
(1) the current density is low. Current densities of research grade H-type cells currently in use in laboratories are typically 50mA/cm2Below, far below 300mA/cm required for industrialization2The current density. Research shows that the current density not only depends on the conductivity and the reactivity of the catalytic material, but also is influenced by mass transfer, namely the diffusion of reactants and the structure of an electrode electrolyte;
(2) product selectivity and separation problems. The copper-based material is the only material currently known to convert carbon dioxide into deeply reduced C2+Metal catalyst of the product. However, the deep reduction brings product selectivity problem, and under the prior art, the reaction product contains C1-C10 molecular products, includingBut are not limited to, carbon monoxide (CO), formic acid (HCOOH), methane (CH)4) Ethylene (C)2H4) Ethanol (C)2H5OH), n-propanol (n-C)3H7OH) and other important bulk chemical raw materials. On one hand, the subsequent product separation brings expensive separation equipment investment, on the other hand, the production cost caused by process loss and energy input is additionally increased, and great obstruction is brought to further industrial application of the technology. The research aiming at the problem in the scientific field at the present stage mainly focuses on the structural design and component regulation of the catalyst, and taking two most important small molecular products, namely ethylene and ethanol as an example, the selectivity of the existing report work respectively reaches about 70 percent and 50 percent at the highest, and a certain distance is left between the targets of more than 90 percent;
(3) stability problems. The stability of the reaction and the operating life of the reaction apparatus are critical to the true touchdown of the electrocatalytic carbon dioxide conversion technology. The current stability problem is concentrated in both catalytic materials and devices. Although tens of thousands of articles are produced in the field of carbon dioxide reduction every year, most of the materials cannot give consideration to the stability of the materials when pursuing the structural design, reaction selectivity and current density of the materials, and the materials with the stabilization time of hundreds of hours are more than 4000 hours which is far lower than the minimum level required by practical industrial application. In addition, flow-type electrolytic cells and laboratory stage H used in the industry-The electrolytic cell of the type has a remarkable corrosion of a gas diffusion layer for promoting the diffusion of carbon dioxide therein after a long time operation at a large current, and finally causes a flooding fault to deactivate a catalyst.
(4) Water management problems. The operating conditions of a flow cell require the consumption of large amounts of high concentration alkaline electrolyte and the production of wastewater, which adds additional costs and safety hazards to the maintenance of production equipment and wastewater treatment.
