Within petrochemical refining and fine‑chemical production systems, the purity and stability of catalytic raw materials directly determine cracking reaction efficiency, finished‑oil quality and production‑line service life. As a mainstream rare‑earth catalytic additive, industrial‑grade praseodymium chloride features stable chemical activity, excellent thermal stability and strong anti‑poisoning performance. It is widely applied in core processes such as fluid catalytic cracking of petroleum, hydro‑reforming and organic synthesis, serving as an essential basic raw material to improve quality‑to‑efficiency performance across the petrochemical sector. Leveraging automated production processes and a high‑quality raw‑material selection system, Sichuan Wonaixi New Materials Technology Co., Ltd. steadily manufactures low‑impurity, high‑activity industrial‑grade praseodymium chloride, delivering consistent bulk catalytic‑raw‑material supply for petrochemical enterprises.

Wonaixi praseodymium chloride dedicated to industrial catalysis is standard hexahydrate praseodymium chloride (PrCl₃·6H₂O, CAS: 10025‑90‑8). The finished product is green crystals with uniform color, stable physicochemical properties, excellent water solubility and acid solubility, compatible with various wet‑process catalyst preparation workflows and industrial reaction systems. Abandoning extensive traditional‑mode production, the company adopts fully‑automated production lines alongside standardized batch‑control procedures. Closed‑loop quality control covers the full workflow: raw‑material screening, fine production, graded impurity inspection and finished‑product delivery. This reliably guarantees stable activity and controllable impurity indicators for every batch, meeting high‑precision catalytic production standards for petrochemical applications.

To satisfy stringent requirements of petrochemical catalysis scenarios, Wonaixi offers two praseodymium‑chloride grades: PL‑2.5N and PL‑3N. The total rare‑earth oxide (TREO) content of products reaches ≥47%, and the high‑purity grade contains praseodymium oxide up to 99.9%. During production, strict controls are implemented over rare‑earth impurities including lanthanum, cerium and neodymium, as well as non‑rare‑earth impurities such as calcium, iron, sodium, lead and aluminum, keeping all impurity contents at a low industry‑leading level. Its low‑impurity property effectively prevents catalyst poisoning and activity decay triggered by heavy‑metal contaminants, making it well‑suited for long‑term continuous petrochemical catalytic‑production conditions.

In petroleum‑cracking catalytic processes, Wonaixi praseodymium chloride acts as an efficient catalytic additive. It optimizes the framework structure of Y‑type zeolite molecular sieves and enhances thermal stability of the catalytic system, enabling production lines to withstand high‑temperature cracking environments. It also improves cracking‑reaction selectivity, promotes full conversion of heavy oil, raises the yield of high‑quality products including gasoline and light oil, upgrades comprehensive finished‑oil quality, and helps refineries boost raw‑material utilization and production benefits.

Beyond mainstream petroleum‑cracking applications, this industrial‑grade praseodymium chloride is also compatible with multiple processes, including chemical hydrogenation reactions, olefin polymerization and fine organic synthesis. The addition of praseodymium‑chloride catalytic additive can effectively accelerate reaction rates, inhibit side‑reactions and reduce waste generation. It assists petrochemical and fine‑chemical enterprises in achieving energy conservation, consumption reduction and green‑production targets, matching production‑upgrade demands across the modern‑chemical industry.

Supported by mature production workflows and standardized management systems, Wonaixi praseodymium chloride delivers outstanding batch consistency. It greatly mitigates common drawbacks of traditional catalytic raw materials, such as large batch‑to‑batch fluctuations and unstable catalytic activity. Consistent product performance ensures long‑term stable operation of petrochemical production lines, cuts catalyst‑replacement frequency and lowers enterprise costs for equipment maintenance and raw‑material renewal, perfectly fitting large‑scale continuous‑industrial‑production requirements.

Considering the industry characteristics of bulk procurement and long‑term stock‑up by petrochemical enterprises, Wonaixi has built a complete supply and protection system. Finished praseodymium‑chloride products adopt multi‑layer protection technology: vacuum sealing, air‑cushion shock‑proof packaging and steel drums, which effectively isolate moisture and contaminants and preserve the activity and purity of catalytic raw materials throughout storage and transportation. Available packaging options include standard 50 kg steel drums and large‑capacity 1000 kg bulk bags. Palletized shipment is supported, compatible with sea freight, air freight and other transport modes, enabling sustained bulk, stable raw‑material supply for petrochemical and fine‑chemical companies at home and overseas.

Deeply engaged in rare‑earth chemical raw‑material industry, Sichuan Wonaixi New Materials Technology Co., Ltd. focuses on R&D and production of raw materials for industrial catalysis. Centered on premium raw materials, automated manufacturing technology and rigorous quality inspection, the company continuously supplies high‑quality praseodymium‑chloride products tailored for petrochemical and fine‑chemical scenarios. In the future, we will further optimize production processes and improve the product‑grading system, delivering highly‑adaptable, stable rare‑earth‑chloride raw‑material solutions for industrial‑catalysis clients and supporting efficient, sustainable development of the chemical‑processing industry.
