Recently, the methane-carbon dioxide self-heating and reforming synthesis gas plant has achieved stable operation at the Shanxi Lu'an Coal-to-oil Base, which is based on the preliminary trial operation and system optimization. On June 21, the plant started the whole system operation and was On the 10th of this month, full-load production was realized. On August 2nd, the on-site calibration organized by the China Petroleum and Chemical Industry Federation was completed. As of the date of the press release, the device has been operating stably for more than 1000 hours, with a daily output of up to 200,000 Nm3 of product gas with a low H2/CO molar ratio, and a daily conversion of up to 60 tons of CO2.

The methane carbon dioxide reforming to syngas technology originated from the methane carbon dioxide reorganization project jointly initiated by the Shanghai Advanced Research Institute of the Chinese Academy of Sciences, Shanxi Panan Mining (Group) Co., Ltd. and the Dutch Shell Petroleum Industry Company. The research work has won the support of the National Natural Science Foundation of China, the key projects of the Shanghai Municipal Science and Technology Commission, the strategic lead of the Chinese Academy of Sciences-coal special projects, the national science and technology support, and the national key R&D program. After an in-depth study of the deactivation mechanism of the catalyst in the initial stage, the research group has made significant progress in the stability of the catalyst against carbon deposition, and the developed catalyst has been operating stably for more than 5,000 hours under simulated conditions. Under the strategic leadership of the Chinese Academy of Sciences-coal special project and national key R&D program-Nano special support, the research team completed catalyst development and reactor simulation studies and engineering amplification and production of 100-ton catalysts, and implemented under the support of Shanxi Luan Group. The construction and operation of Wanfang-level devices.

CO2 and CH4 are typical greenhouse gases and they are also important carbon-containing resources. Using CO2 and CH4 as carbon sources can be converted to synthesis gas (CO and H2) under certain conditions, namely methane carbon dioxide reforming or dry reforming. Compared with traditional steam reforming of methane, methane and carbon dioxide reforming consumes almost no water, but utilizes carbon dioxide in large quantities, reduces energy consumption, and alleviates the pressure for reducing greenhouse gas emissions. Therefore, it is receiving widespread attention in the world. However, this reaction process is particularly prone to carbon deposition, and carbon-resistant catalysts and special reactors are recognized as the core problems in the industrialization of their technologies. Therefore, relevant R&D at home and abroad has not reached the scale of industrial sideline or demonstration. As Dr. Zhang Jun said, the Shanghai Key Laboratory of Low Carbon Conversion Science and Engineering successfully solved the problem of the stability of nanometals, especially the match between catalyst casting and internal structures. Such nano-mesoporous catalysts have the dual functions of coking resistance and anti-sintering, and at the same time, the optimization of matching between the reactor structure and the catalyst is another important factor for success. Based on this, the technology can be extended to steam reforming and multiple application applications, enabling flexible modulation of the syngas H2/CO ratio (0.7-2.0). Therefore, this technology is applicable to the conversion and utilization of conventional or unconventional natural gas (CO2-rich offshore natural gas, shale gas), and also applicable to the utilization of exhaust gas in coal chemical and metallurgical industries.

On August 2, China Petroleum and Chemical Industry Federation developed key technologies for the self-heating and reforming of methane and carbon dioxide for syngas developed by the Shanghai Research Institute of Chinese Academy of Sciences, Shanxi Panan Mining (Group) Co., Ltd., and Dutch Shell Petroleum Industries. The industrial side-line test device was calibrated for 72 hours of continuous operation. The expert group heard the key technologies for the completion of the methane carbon dioxide self-heating reforming of the project and the report on the construction and operation of the industrial sideline test equipment, the report preparation work, the inspection of the site operation conditions, the determination of the calibration plan, and the measurement instruments and analysis instruments. The methods for calculating the method and the calibration indicators were confirmed. During the calibration period, the Group of Experts visited the field operations of the main system such as the field conversion furnace, reviewed the original data records, and examined the control room, analysis room, on-site sampling and other positions one by one to ensure that the calibration data was true and reliable. The experts all agreed that the research has developed a highly efficient nano nickel-based catalyst and a dedicated reactor with superior performance, optimized the process system, and established the first international Nm3/h-scale methane carbon dioxide autothermal reforming synthesis gas industrial side-line device And stable operation, the realization of the efficient use of CO2 resources and product gas H2/CO flexible and adjustable, it is recommended to promote industrialization as soon as possible.

Sun Yuhan, head of the Shanghai Institute of Advanced Science and Technology of the Chinese Academy of Sciences, said that the large-scale methane carbon dioxide reforming technology has completely independent intellectual property rights, and its core is the development of highly efficient catalysts and efficient reactors. The stable operation of the device is a typical case from basic research to demonstration of engineering. It is also the result of the successful cooperation between the Shanghai High-level Research Institute, Shanxi Pan'an Mining (Group) Co., Ltd. and the Dutch Shell Petroleum Industry Company. This technology not only lays an important technological foundation for the large-scale utilization of natural gas rich in CO2, but also makes significant innovations in the low-carbon development of Shanxi's coal chemical industry.

Li Jinping, chairman of Shanxi Pan'an Group, stated that the successful development of the technology for the synthesis of methane and carbon dioxide to produce synthesis gas and the stable operation of the plant have created a precedent for carbon dioxide emission reduction and resource utilization. This major technological breakthrough was made by Chun'an Group to conscientiously implement the five major development concepts of Xi Secretary and the strategic thinking of the energy revolution, and to carry out high-end development in accordance with the strategic deployment of the provincial party committee and provincial government to drive innovation, transform and upgrade, and fight for the energy revolution. The important result of international cooperation is another typical case that promotes the combination of production, study and research.

The stable operation of methane and carbon dioxide reforming to produce syngas installations is a typical case of the Chinese Academy of Sciences’ Shanghai High-level Institute actively implementing the “four lead” requirements, facing strategic needs and technological frontiers, and exploring joint innovations with large companies at home and abroad. It is also a typical example of the establishment of an innovation model for R&D centers in Shanghai, demonstration bases nationwide, and commercialization throughout the world, adding new highlights to the construction of Shanghai Science and Innovation Center with global influence.

At present, the three parties of the cooperation are conducting commercial evaluation of the technology and reached consensus on the commercialization and application of globalization.
