The petrochemical industry relies heavily on the purity of its feedstocks to ensure efficient and profitable production of essential materials. Among the common impurities that challenge this purity, arsenic compounds, particularly arsenic hydride (AsH3), are notorious for their ability to poison catalysts. Addressing this challenge requires specialized purification agents. As a leading manufacturer and supplier of chemical catalysts, we offer a highly effective dearsenic catalyst, specifically designed to tackle these issues in critical petrochemical applications. This article details the scientific principles behind hydrocarbon purification and highlights the specific applications where our catalyst provides significant benefits.

In the production of polymers like polypropylene and in large-scale ethylene projects, feedstock purity is directly linked to catalyst longevity and the quality of the final product. Arsenic, even at trace levels, can irreversibly deactivate the active sites of catalysts used in polymerization, cracking, and other vital processes. For instance, in propylene purification, removing AsH3 is critical to prevent poisoning of downstream catalysts used in polymerization reactors. Similarly, in ethylene plants, ensuring the purity of hydrocarbon streams protects the integrity of the entire process chain.

Our TAS-1 dearsenic catalyst is engineered to meet these exacting demands. This Cu-Zn-Al-M series catalyst offers exceptional performance in removing arsenic hydride and hydrogen sulfide (H2S) from a variety of hydrocarbon streams at room temperature. This makes it an ideal solution for applications where high-temperature operation is not feasible or desirable. Its high arsenic adsorption capacity and robust mechanical strength ensure a long service life, contributing to reduced operational costs and maintenance downtime. We are proud to be a reliable manufacturer and supplier in China, providing solutions comparable to leading international products but at more accessible price points.

Key applications for our dearsenic catalyst include:

  • Propylene Purification: In the production of polypropylene, our catalyst effectively removes AsH3 from propylene streams, safeguarding polymerization catalysts and ensuring the quality of the final polymer product.
  • Propane Dehydrogenation: For processes that convert propane to propylene, our catalyst can be employed to purify the feedstock, preventing catalyst poisoning in subsequent steps.
  • Catalytic Cracking Tail Gas Treatment: The tail gas from catalytic cracking processes often contains various impurities, including arsenic compounds. Our catalyst helps to purify these streams, improving overall process efficiency.
  • General Hydrocarbon Stream Purification: Beyond specific polymers, our catalyst is effective in treating a range of liquid hydrocarbon streams, removing harmful arsenic impurities before they can impact downstream operations.
