Hot 1: China's first catalytic carbon dioxide recovery project in the refining industry put into operation

On October 8, technicians from Sinopec Zhongyuan Oilfield Petrochemical Plant were checking the operation of the equipment in the CO2 recovery project area in Puyang, Henan Province.

Recently, the 100,000 tons/year CO2 recovery project of SINOPEC Zhongyuan Oilfield was put into operation and produced qualified products. With a total investment of 150 million RMB, this project is the first CO2 recovery project in China's refining and chemical industry for catalytic cracking tail gas, and also one of the key environmental protection projects under SINOPEC's "Blue Water, Blue Sky" project. The project can realize the full recycling of refinery tail gas, which is both environmental protection and efficiency creation, providing a new way for energy saving, emission reduction, haze control and improving economic efficiency.

Hot 2: New material can capture carbon dioxide is expected to combat climate change

Foresight Science and Technology, October 20, an international team of researchers from Sweden and South Korea published a report in the latest issue of the journal "Science", they developed a microporous crystalline material that can capture carbon dioxide in humid gases more effectively than existing materials. The new material could be an effective tool in the fight against climate change.

One way to mitigate climate change is to capture carbon dioxide from the air. So far, this has been difficult to implement because the presence of water prevents the adsorption of carbon dioxide, and complete dehydration is an expensive process. The newly developed material, however, is stable and recyclable, and the micropores within its crystals have different adsorption sites for carbon dioxide and water.

As far as I know, this is the first material that can capture carbon dioxide in a humid environment, and is an effective way to fight climate change," said Tsujishu Terasaki, a professor at the Department of Materials and Environmental Chemistry at Stockholm University in Sweden, according to physicistsorgan.org. In other cases, usually water and carbon dioxide compete with each other when they are adsorbed, whereas this material is able to absorb them both at the same time. However, absorbing carbon dioxide is a huge undertaking."

The new material is a copper silicate crystal, which researchers at Seogang University in South Korea have named SGU-29.The material could be used to capture carbon dioxide in the atmosphere, especially for clean emissions.

The researchers say that carbon dioxide is always produced with moisture. They can now combine this with other systems being developed to capture carbon dioxide from moist gases and then convert the collected waste carbon into valuable compounds, and expect to be able to work on implementing this within five years. The most difficult part of the process is capturing the carbon dioxide, and a solution is now available.

Hot 3:Tingnan Coal: Successful implementation of "Liquid Carbon Dioxide Pre-Fracture Blasting" test

Recently, Tingnan Coal Company successfully implemented the "liquid carbon dioxide pre-cracking and blasting" technology test in the 206 working face, exploring a new technology to prevent and control the impact ground pressure in the mine.

With the increase of mining depth in the past two years, the impact ground pressure phenomenon first appeared in the second disk area of the mine, threatening the safety production. To this end, the company strengthened cooperation with Shenyang Coal Academy of Sciences and other professional organizations, and actively explore impact pressure prevention and control technology, "liquid carbon dioxide pre-cracking blasting" test is one of the two sides of the project.

It is understood that the project makes full use of the physical properties of liquid carbon dioxide, by drilling holes in the section of the coal column, loading the blasting cylinder with liquid carbon dioxide, sealing the holes and then connecting the power supply, the blasting cylinder within the heating package generates a large amount of heat so that the liquid carbon dioxide instantly vaporize and destroy the coal body, to achieve the effect of pre-cracking of the coal body.

"This method is not only easy to operate, but also safe. Through the physical reaction of liquid carbon dioxide gasification while doing work externally, the heat released by the heating pack is fully absorbed to avoid detonating gas and coal dust." Tang Zhongyi, deputy director of the company's technology management department, introduced.
