As the birthplace of China’s modern soda ash industry and the origin of Hou’s Combined Soda Process, Tianjin Bohua Yongli Chemical Industry Co., Ltd. carries forward a century-old industrial heritage. Amid the wave of industrial upgrading, it has centered its development on technological independence, intelligent production and business diversification, completing its transformation from a traditional basic chemical manufacturer to an integrated provider of high-end new materials and new energy, and setting a benchmark for time-honored chemical enterprises pursuing innovation while preserving heritage.
In terms of core technological independence, the company spent over a decade breaking through the regeneration and refining technology for rhodium catalysts used in oxo synthesis of butyl octanol, ending the industry’s long-term reliance on imported high-end catalysts and earning the title of Tianjin Municipal Manufacturing Single Champion. With its octanol optimization project reaching full production in 2026, its total butyl octanol capacity has exceeded 1 million tons per year. Supported by continuously optimized capacity for fine chemical products such as polyoxymethylene and acetic acid, multiple quality improvement projects have been selected as municipal-level benchmarks, and its raw material utilization rate and energy consumption indicators for core production units remain at the leading level in the industry.
Digital-intelligent transformation has been the company’s core focus in recent years. It is advancing the second phase of its "Intelligent Control · Zero Manual Operation" project, extending smart management technology to core production units including gasifiers, synthetic ammonia and butyl octanol facilities. Its AI-powered dynamic equipment fault diagnosis system, developed in collaboration with universities, won an award at the National Chemical Industry AI Innovation Competition, enabling accurate prediction of core equipment failures. This has driven the production model to shift from "manned on-duty" to "intelligent management", with simultaneous improvements in intrinsic safety and production efficiency.
Its green new sector layout is also accelerating. The company has built one of the largest industrial by-product hydrogen purification bases in the Beijing-Tianjin-Hebei region. Its two-phase hydrogen refueling mother stations have an annual capacity of 7,000 tons, producing electronic-grade high-purity hydrogen with a purity of 99.9999%. It has obtained China’s first batch of clean hydrogen certification for fuel cell vehicles, expanded its food-grade soda ash and sodium bicarbonate product lines, and completed the full chain of resource utilization of industrial tail gas, delivering remarkable annual carbon reduction benefits.
Leveraging its geographical advantage near Tianjin Port, its products are exported to more than 30 countries and regions worldwide, and it historically provided soda ash technical assistance to multiple countries. Looking ahead to the 15th Five-Year Plan period, Bohua Yongli continues to expand into high-end new chemical materials and the hydrogen energy industrial chain, driving the century-old brand to climb up the value chain through innovation.
