The company has rich experience in the research, development and application of catalysts and adsorbents, providing technical parameters for engineering projects, screening qualified suppliers at home and abroad, and testing the quality of adsorbents used in the project to ensure the project quality. Three editions of the Application Manual of Industrial Adsorbents have been published, covering the static and dynamic adsorption performance curves of about hundreds of adsorbents in five major categories of nearly 100 enterprises at home and abroad. Special research and development have been carried out for adsorbents and catalysts in special fields, and major breakthroughs have been made in the technologies of catalysts such as high-efficiency copper catalysts for methanol hydrogen production, wide-temperature chrome-free medium-shift catalysts, high-efficiency copper adsorbents for CO, and a number of technologies have reached the international advanced level.

J641-AL series valves are special pneumatic valves designed and manufactured according to the technical requirements of High-Performance Pneumatic Globe Valves in the domestic PSA hydrogen extraction unit and national standards, including normal temperature type and high temperature type; The program-controlled valve has small volume, light weight, fast action, good sealing performance, long service life and high reliability.

The production of hydrogen peroxide (H₂O₂) by anthraquinone method is one of the most mature and common production methods in the world. At present, there are 27.5%, 35.0% and 50.0% products in the market in China.

The raw materials for methanol production can be natural gas, coke oven gas, coal, residual oil, naphtha, acetylene tail gas or other waste gas containing hydrogen and carbon monoxide. Since the 1950s, natural gas has gradually become the main raw material for methanol synthesis. At present, more than 90% of the plants in the world use natural gas as the raw material. Because the process of methanol production from natural gas is short, investment is low, production costs are low, and the emissions of three wastes are low, it is a vigorously promoted clean energy.

Use natural gas, coke oven gas, acetylene tail gas or other sources containing rich hydrogen as raw materials to build small and medium-sized synthetic ammonia plants. It has the characteristics of short process flow, low investment, low production cost and low discharge of three wastes, and is a production and construction mode of synthetic ammonia that can be vigorously promoted.
