December of this year, Inner Mongolia Autonomous Region CO 2Capture and Recycling Engineering Research Center was formally established in less than a year, and in this short period of time, the research team handed in a high-quality questionnaire - polyol - ethylenediamine water system catch Set industrial gas CO 2law.
On November 25, Science and Technology Daily reporter saw Professor Zhang Jianbin, director of the center in the laboratory of Inner Mongolia University of Technology Research Center. He first demonstrated the latest achievements in team research: CO 2SM (carbon dioxide storage material), a fragrant white powder, said: 'Our core technology is called' Polyol - Ethylenediamine Water System '. This new CO 2Capture method so that CO 2Capture and low cost resources becomes possible. '
The data show that due to the strong volatility of the amine, the traditional alkanolamine trapping method is used in industry to process 14,900 cubic meters of CO 2Exhaust gas, the use of amine costs about 4000000 yuan, such a cost is obviously difficult to be accepted by most businesses.While in the polyol - ethylenediamine water system capture industrial gas CO 2In the system, scientists at the research center have achieved key technological steps to immobilize ethylenediamine with polyols.
'We found through the hydrogen bond between the alcohol and amine hydrogenation and ionization of ethylene glycol polyols on the ethylene diamine fixation.This method can achieve flue gas CO 2The recovery is higher than 99%, the amine regeneration rate is higher than 90% and the amine loss rate is reduced by 80% 2Of the capture costs will be expected to be reduced to 20% of the original. "Zhang Jianbin said.
At present, Inner Mongolia CO 2Capture and Resource Engineering Research Center is the second provincial-level carbon dioxide capture platform, but also the first provincial-level carbon dioxide resource utilization platform.Chemical engineer, University of Science and Technology Beijing University of Chemical and Biological Engineering Professor Li Xin Xue said: Compared with another platform for capturing and storing carbon dioxide, the research center in Inner Mongolia has realized the seamless connection of carbon dioxide capture and resource recovery, which can realize the in-situ absorption of carbon dioxide and realize the resource utilization in situ. This new scientific research achievement In line with the more developed Inner Mongolia Autonomous Region of the coal industry, and can quickly promote the country.
How to achieve new brand new resource utilization? Professor Zhang Jianbin and his team with CO 2SM gives the answer. 'This is the' polyol - ethylenediamine water system 'at CO 2A new material formed during the capture process, CO 2It is a kind of salt, we named it as' carbon dioxide storage material ', the only one in the world at present,' Professor Zhang said with a bottle of white powder.
Hong Hailong, deputy director of the Research Center told Sci-Tech Daily reporters: 'As a new CO 2For example, this material is polyurethane after dewatering and can be used in the field of fine chemicals. After adding water, it is a non-toxic plant activator with 20% higher plant growth rate than traditional fertilizers. And industrial waste carbide slag mixing, you can easily synthesize nano calcium carbonate ... ... '
Through the research of carbon dioxide storage materials, researchers at the research center have found and demonstrated the wide availability of such materials, and successively carried out the preparation of coal gangue adsorbents, the development of refined chemical processes, the supercritical extraction method and the drug- Refinement, activation of plant growth and food preservation, preparation of carbide calcium carbide and other control and CO 2Trapping and resource technology are closely related to important process demonstration and technology research and development projects, approved 6 national invention patents, approved 9 national research projects.
With the research papers published in the ACS "Applied Materials & Interfaces" and other academic journals, Inner Mongolia CO 2Capture and Recycling Engineering Research Center of the research results have begun to enter the pilot phase.
Chemistry and molecular engineering scientist, Professor Wei Xionghui of Peking University spoke highly of this brand new scientific research achievement in Inner Mongolia: "With CO 2Replacing oil and gas as a future carbon source is of great significance and is the main objective of scientific exploration and research in the relevant fields in the future. The polyol-ethylenediamine water system captures industrial CO 2The establishment of a "system" and the utilization of carbon dioxide storage materials provide a new direction for this goal.
