Recently, Runhe Catalyst Co., Ltd. (hereinafter referred to as "Runhe Catalyst")At the 7th National Alkane Dehydrogenation Industry Innovation and Development Forum held in NingboA new product has been launched.

Professor Zhuo Runsheng, Chairman of Runhe Catalysis Company, announced that the company's independently developed chromium-based fixed-bed propane dehydrogenation catalyst (hereinafter referred to as "PDH") has successfully achieved its first domestic industrial application. After more than 20 years of dedicated research, it has been stably operating in a 500,000-ton/year industrial unit of a domestic petrochemical company for over a year, with all technical indicators comprehensively surpassing international leading levels.

Key indicators comprehensively surpassed

From following to leading.

As one of the core processes for producing propylene, propane dehydrogenation technology has long been exclusively controlled by American companies. Although China accounts for more than 70% of the global PDH production capacity, it has always faced risks such as high patent licensing fees and an unstable supply chain.

Ruhnhe Catalyst has delivered an exciting report: a single-pass propane conversion rate of 44%, propylene selectivity of 88.2%, unit capacity load increased to 108%, coking resistance improved by 30%, mechanical strength enhanced by 40%, bed pressure drop control during reaction and regeneration stages reaching the best level in the industry, CO₂ content in ethane-free tail gas below 3 mol%, and overall performance has comprehensively surpassed similar foreign products.

Zhuo Runsheng stated, "This breakthrough is by no means a simple localization but rather a technological upgrade of catalyst performance. Through more than 50 invention patents, we have built a technological barrier that ensures Chinese companies make the leap from following to leading in the field of alkane dehydrogenation."

Comprehensive coverage of breed production capacity

From import to export with promising prospects

In terms of the catalyst supply chain, as a company with the capability to produce fixed-bed, fluidized-bed, and moving-bed dehydrogenation catalysts, Runhe Catalysis has invested 600 million RMB from 2021 to 2023 to establish the Zhoushan base in Zhejiang. The PDH catalyst has an annual production capacity of nearly 10,000 tons, enabling it to provide a comprehensive range of high-quality dehydrogenation catalysts with excellent service to the global market efficiently.

After the release of this technology, it has attracted widespread attention in the chemical industry. Industry experts have pointed out that this breakthrough is of milestone significance: for enterprises, the procurement cost and cycle of catalysts are greatly reduced, inventory pressure is lowered, and localized technical services are more convenient; for the industry, China’s PDH production capacity has exceeded 23 million tons per year, accounting for 32.3% of the total propylene capacity. The breakthrough in PDH catalyst technology is conducive to accelerating industrial structure optimization, enhancing the resilience of the industrial chain, and promoting the internationalization of PDH technology.

Runhe Catalysis has adopted continuous technological innovation as its development strategy, achieving a leap from following to leading in the industry. It has now become the second largest catalyst company in China, with an annual catalyst production capacity of 50,000 tons and more than 100 product varieties. Its products are sold in over 20 countries and regions, including the United States, India, and the Middle East, providing core catalytic materials support to more than 30 large petrochemical enterprises both domestically and internationally.
