Vanadium catalyst can be used in the field of VOCs treatment. Industry development faces challenges

Vanadium catalyst refers to a chemical reagent that uses the good catalytic properties of vanadium compounds to change the rate of certain chemical reactions without participating in the reaction itself. Vanadium catalysts have the advantages of low toxicity, increased reaction rate, good sulfur resistance, and good durability. They are widely used in olefin polymerization, desulfurization catalysis, VOCs treatment, ammonia synthesis, oxidation catalytic reactions and other fields.

Vanadium catalysts usually use vanadium compounds as the base material, and vanadium pentoxide is widely used in its production process. Vanadium pentoxide, also known as vanadium anhydride, is an inorganic compound that appears as an orange-yellow crystalline powder and is commonly used as an industrial catalyst. my country’s abundant vanadium ore resources have driven the rapid expansion of vanadium pentoxide production capacity and continued growth in output. In 2021, my country’s vanadium pentoxide production capacity will reach 175,000 tons, and its output will reach 141,000 tons. The advantages of raw materials lay a good foundation for the development of the vanadium catalyst industry.

Vanadium catalyst preparation methods include sol-gel method, mechanical method and impregnation method. The sol-gel method has the advantages of low roasting temperature and good finished product quality, but the aging time is long; the mechanical method is the main preparation method of vanadium catalyst, and has the advantages of convenient operation and industrial production; the impregnation method has low operating cost and Mainly used to prepare highly active vanadium catalysts. Drying is a key link in the production of vanadium catalysts. Traditional microwave drying methods have shortcomings such as high energy consumption and slow drying speed. In recent years, Chinese companies have continued to increase research on green drying processes for vanadium catalysts, which will further improve the quality of my country’s vanadium catalysts.

According to the “2023-2028 China Vanadium Catalyst Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, vanadium Catalysts have a wide range of applications. In the field of VOCs treatment, vanadium catalysts have good durability, can resist toxic gases such as sulfur dioxide, and convert VOCs into harmless substances. VOCs are volatile organic compounds that can be produced through industrial emissions, vehicle exhaust emissions, kitchen fume emissions, etc., and can easily cause pollution to the environment. In recent years, driven by national environmental protection policies, my country’s VOCs treatment technology has been continuously improved, driving the market demand for vanadium catalysts to become increasingly strong.

At present, there are still certain challenges in the development of the vanadium catalyst industry. On the one hand, compared with iron/zeolite molecular sieves and copper/zeolite molecular sieves, vanadium catalysts have disadvantages in thermal stability and conversion rate, and their market share is relatively low; on the other hand, my country’s vanadium catalyst market is dominated by Witten catalysis, element Mainly small and medium-sized enterprises such as Chen Environmental Protection, the industry concentration is low, and the market lacks leading companies.

Industry analysts said that vanadium catalysts have broad application prospects in the field of VOCs treatment. In the future, as market demand is gradually released, the industry development trend will Keep improving. At present, vanadium catalysts still have certain shortcomings in performance, resulting in a low market share. In the future, as local companies continue to increase their investment in research and development, my country’s vanadium catalyst industry will develop in the direction of high performance.
