The State Key Laboratory, known as the "Golden Signature" for scientific research, has opened its doors to enterprises and focused on commonalities and key technologies in the industry. It hopes to guide and stimulate a group of companies to devote themselves to technological innovation for a long time, taking into account the needs of the company's own development. At the same time, we will use the radiation and driving role of the entire industry. Selected companies have undergone rigorous screening and expert review. The Ministry of Science and Technology also stipulates that enterprises should engage in research on application foundations, key technologies, and generic technologies for more than five years; master industrial core technologies and have independent intellectual property rights; and the proportion of annual sales revenue for research and development in the last three years should not be less than 5%; Advanced scientific research conditions and facilities.
China is a big country with a lack of resources. The energy structure of lean oil, low gas, and relatively rich coal will replace the oil supply with liquid fuel produced by coal liquefaction. This will be an inevitable trend. Shanghai Yankuang Energy Technology R&D Co., Ltd. is a research and development company with independent legal person status controlled by Yankuang Group. It is mainly engaged in the research and development of coal chemical industry, especially coal liquefaction technology. The focus includes the development and application of high-efficiency catalysts, chemical reactors and chemical process flow. Design and optimization, as well as research and development of separation technologies. It has independently developed coal oil technology for many years and successfully conducted pilot tests. The independent innovation of coal liquefaction and coal chemical technology is at the leading position in China. At the end of 2003, a pilot plant with an annual output of 10,000 tons of coal-based oil was completed. It was successfully started and continuously operated for nearly 8 months. The overall level reached the first-class in the world and the first in the country. The indirect liquefaction of millions of tons of coal based on this technology was established. Oil industry demonstration devices are actively advancing. Shanghai Yankuang Energy Science and Technology R&D Co., Ltd. was selected as one of the first batch of state key laboratories of enterprises, and will further promote the construction of a technological innovation system that integrates enterprise as the mainstay, market orientation, and the combination of production, study and research, and develops key technologies with independent intellectual property rights to form its own The core technologies and proprietary technologies enhance the company's core competitiveness.
1. Background of the State Key Laboratory of Coal Liquefaction and Coal Chemical Industry The Outline of the Eleventh Five-Year Plan for National Economic and Social Development clearly put forward the development of the energy industry, insisting on saving priority, based on domestic, coal-based, multiple development, and optimization. The production and consumption structure will build a stable, economical, clean and safe energy supply system.
At present, China has become the world’s second largest oil consumer and importer. In 2004, the net amount of crude oil imports was 121.4 million tons. In 2005, the net imports of crude oil and refined oil were 13617 million tons. In 2006, the net imports of crude oil and refined oil reached 16,287 million tons. In 2007, China’s oil imports reached 163,175 million tons. The degree of dependence on oil soared from 42.9% in 2005 to 47.3% in 2007. The Ministry of Commerce estimates that China’s oil consumption will be 4.5-610 million tons by 2020, and domestic oil production will be 180 million tons by that time, and the external dependence will reach 60%.
With the further development of the national economy, the contradiction between the supply and demand of China's oil will become more prominent, and the dramatic increase in the volume of oil imports will surely adversely affect the country’s energy security. Coal liquefaction and synthetic oil products are the most effective and feasible ways to solve the shortage of liquid fuels and achieve energy diversification. Coal-based oil production has become an important strategic choice for ensuring energy security.
In this context, the Ministry of Science and Technology approved the establishment of a “State Key Laboratory of Coal Liquefaction and Coal Chemical Industry†based on Shanghai Yankuang Energy Science and Technology R&D Co., Ltd., to develop coal liquefaction and coal chemical commonality and key technology research and development, with emphasis on fees. The independent R&D of care synthetic technology provides technical support for the industrialization of coal liquefaction technology in China.
