* * Key R&D plans: Coal-to-Long Chain Alpha Olefin Project Launched Author/Source: Chemical Network Coal Chemical Industry Date: 2023-04-01 Click rate: 135 Recently, by * * Led by the Energy Group Beijing Low-Carbon Clean Energy Research Institute * * The launch meeting of the key research and development plan "Long-chain α-olefins production technology by direct conversion of low carbon dioxide selective synthesis gas" (α-olefins production technology) was recently held in Beijing Future Science City. It will strive to form a long-chain α-olefins production technology with an annual output of 100,000 tons during the "14th Five-Year Plan" period. “As a high-end chemical raw material, "long-chain α-olefin" is a strategic core raw material for synthetic lubricants, plasticizers, high-end pipes, auto parts, pharmaceuticals and other industries. Currently, the mainstream method for commercialization of long-chain α-olefins in the world is the polymerization of short-chain olefins. However, this technology is used by some European and American companies. * * monopoly. In the domestic research and development of the production method of this strategic core raw material, a "different approach" has been adopted - that is, using coal synthesis gas for direct conversion, first converting coal into synthesis gas through gasification technology, and then using catalytic means to convert the synthesis gas into a mixture of long-chain α-olefins and purify it. Why take this technical route? The project leader of the Low Carbon Institute introduced that on the one hand, the technical route of short-chain olefin polymerization has been adopted by some European and American * * Conquer and achieve commercialization. If we continue to tackle the problem at this time, we will lose the first-mover advantage. ； On the other hand, conversion through coal synthesis gas is in line with my country's national conditions with abundant coal reserves. It also simplifies the conversion steps and is expected to reduce costs. “At present, the international community has failed to achieve mature commercialization of this new technology, which means that we may 'change lanes and overtake' through this technical route. ”said the project leader. According to reports, at present, the technology of using coal synthesis gas to produce long-chain α-olefins has achieved preliminary results in the laboratory. However, in order to realize the transformation of the results, this technology needs to be put on a larger "stage" for verification. “In the next step, we will cooperate with chemical companies to gradually build 100-ton and 10,000-ton production equipment and conduct further research and development until it can be commercialized. ” It is reported that the technology project for producing long-chain α-olefins was launched during the “14th Five-Year Plan” period. * * It is one of the first batch of special projects under the key research and development plan "Clean and Efficient Coal Utilization Technology". It is led by the Low Carbon Institute and jointly undertaken by industry, academia, research and application teams composed of 10 domestic advantageous units. The project is expected to form a long-chain α-olefin production technology with an annual output of 100,000 tons. It will not only achieve high-end, diversified and low-carbon clean conversion of coal in my country, but is also of great significance in solving the problem of my country's excessive dependence on foreign long-chain α-olefins.
