Shaanxi Kaida new palladium catalyst empowers overseas projects to set the benchmark, demonstrating the hard strength of the national catalytic industry

Recently, there is great news from Tarakan, Indonesia - the 192 tons/day (100% discount) hydrogen peroxide plant of Singapore Golden Eagle Group PRI Company was completed and put into operation on December 4, 2024, and the continuous operation days exceeded 340 days by December 2025, setting a new record for the long-term operation of large-scale hydrogen peroxide plants in the industry. Behind this benchmark achievement, the core support comes from the new palladium catalyst independently developed by Shaanxi Kaida Chemical Co., Ltd. With excellent performance, the catalyst perfectly matches the innovative process of the project, which not only guarantees the efficient and stable operation of the plant, but also realizes the double breakthrough of energy saving and consumption reduction and green production, fully demonstrating the technical hard strength of our country's national catalytic enterprises.

As the core supplier of this overseas benchmarking project, our new palladium catalyst has become the "core engine" for the operation of the device. The catalyst adopts advanced precious metal impregnation technology, presents a brown-yellow spherical structure, and has the significant advantages of low bulk density (0.40~ 0.45g/ml) and rich pores. It has also achieved a technological breakthrough of precise and controllable impregnation depth of precious metal palladium and strong adhesion. In practical applications, it can complete 180 tons/day output; after about 15 days of continuous operation, due to the need for full load 192 tons/day (discount 100%) capacity assessment, access to the second hydrogenation tower in series, and easily complete the full load assessment. The adaptation capacity and production efficiency far exceed the industry congeneric products.

Relying on the excellent performance of the catalyst, the key indicators of the PRI hydrogen peroxide plant of the Golden Eagle Group have reached the advanced level in the industry. The running data show that during this operation, the concentration of hydrogen peroxide is 30-32%, the residual content is < 0.12g/L, and the degree of hydrogenation is controlled by < 36%; 2-ethylanthraquinone is added according to 70% of the designed consumption, and the total anthraquinone content is not reduced, and the degradation of the system working fluid is not observed to increase; the content of tetrahydroanthraquinone rises from 18g/L at low load to 30g/L, which is very good; the consumption of 2-ethylanthraquinone in the device is only 0.17Kg/t (27.5%), the consumption of alumina is about 2.5Kg/t (27.5%), and the consumption of aromatics is reduced to 0.87Kg/t (27.5%). The unit consumption of various raw materials is significantly lower than the industry average, which significantly reduces the production cost for the owner. At the same time, with the double-tower tandem design of the hydrogenation system of the device and the patented technology of hydrogen-nitrogen cycle self-cleaning hydrogenation, the problem of local flooded tower caused by high catalyst activity in the early stage was successfully solved, and zero venting of hydrogenation tail gas was achieved, effectively reducing VOC emissions, and practicing the concept of green production.

The successful landing of this overseas project is a strong confirmation of our company's technical R & D strength and product quality. The relevant person in charge said that the success of this overseas benchmarking project is a vivid practice of our company's concept of "empowering industrial upgrading with scientific and technological innovation". In the future, our company will continue to deepen the field of precious metal catalysts, focus on key tracks such as new energy and green chemical industry, continue to promote technological innovation and product iteration, and empower the green and low-carbon development of the global chemical industry with more high-quality and high-performance catalytic products.
