Molybdenum trioxide is widely used and attracts attention in the catalyst field

Molybdenum trioxide is an inorganic substance with a molecular formula of MoO3 and a molecular weight of 144. It is a white crystalline powder, slightly soluble in water, soluble in concentrated nitric acid, concentrated hydrochloric acid, and easily soluble in concentrated alkali. Molybdenum trioxide is produced by burning molybdenite or by adding hydrochloric acid to ammonium molybdate to precipitate molybdate acid and then heating and melting it. It can also be obtained by directly calcining ammonium molybdate.

Molybdenum trioxide is composed of [MoO6] octahedron with metal atoms Mo in the center and oxygen atoms at the corners as the basic structural unit. They share corners and form chain connections. Each two similar chains share edges and form a layered MoO3 stoichiometry. Structure, the layers are staggered and arranged by the van der Waals force. This excellent characteristic makes it have broad application prospects in information display and storage, catalysts, sensors and other fields. Especially in the process of selective oxidation and ammoxidation of hydrocarbons, catalysts with molybdenum trioxide as the main component have been widely researched and applied due to their high activity and selectivity. According to the “2021-2026 China Molybdenum Trioxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, the global The market size of molybdenum trioxide exceeds 20 billion yuan.

Due to the extremely uneven distribution of global molybdenum ore resources, global molybdenum trioxide production companies are mainly concentrated in countries with rich molybdenum ore resource reserves. The molybdenum trioxide industry in Europe, North America, South America and other regions has developed earlier, has rich experience in production, research and development and application, and has strong competitiveness in the global market. The main manufacturers include Molibdenosy Metales S.A, Freeport-McMoRan and Codelco, etc. . Domestic molybdenum resources are mainly concentrated in Henan, Shaanxi and Jilin provinces, which account for more than half of the country’s molybdenum resource reserves. Companies include Jinduicheng Molybdenum Co., Ltd., Luoyang Luanchuan Molybdenum Group Co., Ltd., Liaoning Xinhualong Dayou Molybdenum Industry Co., Ltd., etc.

Industry analysts said that China is the largest new refining capacity region in the Asia-Pacific region. As global industries continue to shift, China will gradually become the world’s largest chemical producer, and its refining capacity will continue to grow. At the same time, with the continuous upgrading of the structure and technology of the petrochemical industry, the demand for catalysts in the oil refining process will increase, which will in turn drive the development of the molybdenum trioxide industry.

Although the scale of China’s molybdenum trioxide industry has continued to expand in recent years, and product quality and production technology levels have continued to improve, there are still many development problems or bottlenecks in the industry. Compared with Western developed countries, the research, production and application of molybdenum trioxide in China is relatively late. Although there is a certain domestic production capacity, there are still certain gaps in molybdenum selection technology and automated production technology, resulting in high production costs for some companies. , product quality is unstable. In terms of the production of high-end products, there is a certain gap between China and leading companies in the United States, Germany and other countries. As a result, domestic companies still need to import a small amount of high-end products.
