After setting the goal of peaking its carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060, China is now promote energy conservation and emission reduction in various industrial sectors, including the traditional chemical industry.
The Ministry of Industry and Information Technology has released a plan for the green development of its industrial sectors during the period of the 14th Five-Year Plan (2021-2025), a step forward in the country’s pursuit of ‘low carbon growth using technology.
The plan urges traditional sectors, such as petrochemicals, steel and non-ferrous metals, to make low-carbon upgrades and transform into greener industries. Meanwhile, the annual Central Economic Work Conference in December pledged to strengthen the clean and efficient use of coal.
In the chemical industry, greener practices benefit from the latest technological advances in chemical synthesis. This means that sub-industries such as fuel chemicals, inorganic chemicals, and organic chemicals are becoming more environmentally friendly, with indirect benefits across a wide range of sectors.
In 2021, Chinese researchers made several scientific and technological breakthroughs in chemical synthesis. These include a method of synthesizing starch from carbon dioxide, the first of its kind in the world, and a method of producing proteins using industrial exhaust gases containing carbon monoxide. , carbon dioxide and ammoniacal water.
Advances in 2021 also include the conversion of carbon dioxide and water to pure formic acid, the transformation of biopolyols to carbon monoxide at room temperature and atmospheric pressure, and the production of ethylene by hydrogenation of acetylene in mild conditions. More than 10 projects related to the petrochemical and chemical industries of coal were awarded. They included catalytic cracking processing technology, efficient exploitation of coal bed methane and rock oil, and crude oil recovery.
Among them, the nanocontained catalysis project won first prize at the State Natural Science Awards. This project achieved the direct and efficient synthesis of light olefins and high-value chemicals such as ethylene, propylene and butene from coal syngas, with less consumption of water and energy and less carbon emissions.
These achievements, ranging from laboratory experiments to industrial production, mean that the basic materials for the chemical industry, such as ethylene, carbon monoxide, starch and protein, can be produced in a much larger way. environmentally friendly than traditional methods and with lower energy consumption and emissions.
The MIIT plan encourages the petrochemical industry, a branch of the chemical fuels industry, to focus on direct production from crude oil and the use of syngas from coal. China’s largest oil refiner has announced its success in the industrial application of crude oil steam cracking technology, which can directly transform crude oil into ethylene and propylene by skipping the traditional refining procedure.
Thanks to the new technology, 1 million metric tons of crude oil can produce about 500,000 tons of various chemicals, including about 400,000 tons of high value-added products such as ethylene, propylene, light aromatics and l ‘hydrogen. The technology of catalytic cracking of crude oil, another technical route which can also transform about 50% of crude oil into various chemicals. The combination of the two cracking technologies should bring the turnaround rate to 70%.
Supported by advanced technology, chemical factories in China have started to reduce their carbon emissions. In Shanghai, in eastern China, there is already a refinery that produces carbon neutral products. The Shanghai Environment and Energy Exchange issued the country’s first carbon-neutral petroleum certificate to a batch of refinery products manufactured by Gaoqiao Petrochemical, a subsidiary of Sinopec in Shanghai.
As OpenGov Asia reported, a white paper shows that artificial intelligence (AI) applications will help China reduce more than 35 billion tonnes of carbon emissions by 2060, the year the nation s ‘is committed to achieving the objective of carbon neutrality. At least 70% of China’s carbon reductions will involve AI-related technologies by 2060. The white paper was jointly published by research firm International Data Corporation (IDC) and a Chinese tech company that has been heavily invested in AI technology in recent years.
