Recently, under the efficient execution of Junyuan Petroleum Group’s South China Sales Frontend Development and International Trade teams, the company successfully completed its first export of high-quality Cyclopentane to the Netherlands. This milestone marks a breakthrough in expanding the international high-end fine chemicals market for Junyuan Petroleum.

Cyclopentane, as an eco-friendly blowing agent, is widely used in polyurethane insulation materials for refrigerators, cold chains, and other applications due to its low toxicity and minimal ozone depletion potential. The product’s quality requirements are extremely stringent. The South China Sales team closely coordinated with Cyclopentane production facilities, deeply participating in production scheduling to ensure a stable supply of high-quality products for the export order.

Relying on an in-depth understanding of factory production capabilities and processes, the team efficiently coordinated production, quality control, and warehousing, strictly monitoring key pre-shipment indicators. Optimal logistics plans were designed and executed to guarantee that each batch of Cyclopentane meets international customers’ high standards in terms of quality, quantity, and timely delivery. This meticulous approach laid a solid foundation for winning customer trust and recognition.

Looking ahead, Junyuan Petroleum’s South China Sales team will continue to actively expand the global market, focusing on high-end demand, strengthening upstream factory collaboration, and optimizing product supply capabilities. By doing so, the company aims to support the internationalization of Junyuan’s high-quality, low-carbon, and eco-friendly chemical products, contributing to a sustainable and competitive presence in the global fine chemicals industry.

High-Purity n-Hexane: A Competitive Edge Driven by Hydrogen Innovation

In the world of industrial chemistry, n-hexane (C₆H₁₄) plays a vital role as a solvent and intermediate—used in everything from edible oil extraction and rubber synthesis to precision laboratory analysis. Yet behind its seemingly simple molecular structure lies a complex challenge: how to transform crude n-hexane, often laden with sulfur compounds, olefins, aromatics, and trace metals, into a high-purity product that meets the demands of food, pharmaceutical, and electronics-grade applications.

The answer? A cutting-edge solution known as hydrogen refining—a molecular-level purification journey powered by precision chemistry and sustainable innovation.

🧪 The Hidden Impurities: Why Crude n-Hexane Needs Refining

Crude n-hexane derived from petroleum cracking contains a cocktail of unwanted guests:

• Reactive olefins like 1-hexene and cyclohexene, prone to side reactions
• Sulfur compounds such as carbon disulfide and mercaptans, corrosive and odorous
• Aromatic hydrocarbons like benzene and toluene, which pose safety risks
• Trace metals from catalysts and equipment wear, compromising product stability

These impurities degrade solvent performance, increase volatility, and may release toxic byproducts during use. Purity isn’t just a preference—it’s a necessity.

⚗️ Hydrogen Refining: A Two-Stage Molecular Purification

Hydrogen refining uses H₂ gas and advanced catalysts to chemically transform impurities into stable, separable compounds. The process unfolds in two meticulously controlled stages:

Stage 1: Targeted Removal of Reactive Impurities

Under high temperature (200–400°C) and pressure (5–10 MPa), crude n-hexane reacts with excess hydrogen in a fixed-bed reactor. Catalysts like Co-Mo or Ni-Mo on alumina initiate:

• Olefin saturation: Double bonds convert to single bonds, stabilizing the molecule
• Desulfurization: Sulfur bonds break, forming hydrogen sulfide (H₂S)
• Denitrogenation and deoxygenation: Nitrogen and oxygen impurities become ammonia (NH₃) and water

This stage removes over 90% of active contaminants.

Stage 2: Deep Purification with Noble Metals

The partially refined product enters a second reactor at even higher conditions (300–450°C, 10–15 MPa), where platinum or palladium catalysts deliver:

• Aromatic hydrogenation: Benzene rings convert to cyclohexane, eliminating carcinogenic risks
• Ultra-trace sulfur removal: Sulfur levels drop to ppb (parts per billion)
• Metal ion capture: Catalyst surfaces adsorb residual heavy metals

The result? n-Hexane with >99.5% purity, meeting stringent standards for sensitive applications.

🔧 Smart Refining: Precision Meets Sustainability

Modern hydrogen refining systems integrate advanced technologies:

• Infrared temperature sensors for real-time reactor monitoring
• Membrane-based hydrogen recycling, achieving >95% reuse
• Catalyst regeneration via controlled oxygen burn-off, extending life to 3–5 years
• Online mass spectrometry for automatic process optimization

These innovations enable annual throughput exceeding 100,000 tons per unit, while reducing energy use by 20% and carbon emissions by 15%.

🌱 A Green Chemistry Breakthrough

Compared to traditional acid washing or distillation, hydrogen refining offers clear environmental advantages:

• Zero liquid waste: Byproducts like H₂S are recycled into elemental sulfur
• Low VOC emissions: Closed systems minimize solvent loss
• Energy recovery: Reaction heat is converted into steam for other plant operations

Each ton of high-purity n-hexane produced via hydrogen refining cuts CO₂ emissions by 1.2 tons—equivalent to planting 65 fir trees.

🔬 The Future: Nano Catalysts and AI Optimization

As material science advances, hydrogen refining is entering a new era:

• Single-atom catalysts boost active sites tenfold, maximizing efficiency
• Machine learning models optimize reaction kinetics and process parameters
• Modular reactor designs offer scalable solutions for SMEs and remote facilities

From petrochemicals to semiconductors, edible oils to pharmaceuticals, the demand for ultra-pure n-hexane is rising. Hydrogen refining isn’t just a technical upgrade—it’s a strategic leap toward cleaner, smarter, and more sustainable chemical manufacturing.

Junyuan Petroleum Group, China’s largest n-Pentane producer, has successfully achieved continuous exports for the 19th consecutive year. Recently, 260 tons of n-Pentane were shipped from Qingdao Port to Colombia, marking another solid step in the company’s steady expansion into international markets.

Over the past years, Junyuan has actively promoted the transformation and upgrading of the petrochemical industry by relying on advanced naphtha chemical technology. Its products not only hold a strong position in the domestic market but also represent a leap from “Made in China” to “Global Solutions.” Through in-depth market research and front-line engagement, Junyuan has strategically targeted regions such as Southeast Asia and South America. By collaborating with major domestic trading partners, participating in international exhibitions, and opening up trade channels along the Belt and Road, the company has significantly expanded the global reach of its n-Pentane products.

In Colombia, particularly in the port cities of Buenaventura and Cartagena, n-Pentane plays a vital role:

Blowing Agent in polyurethane (PU) and polystyrene (EPS) foams, essential for insulation in refrigerators and construction panels.

Organic Solvent in adhesives, coatings, and inks.

Electronics Cleaning Agent to remove grease and impurities in manufacturing processes.

Refrigerant Component (R601) in eco-friendly cooling systems.

Chemical Intermediate, Laboratory Applications, and Specialty Uses in fine chemicals, chromatography, and performance-enhancing materials.

With its “Terminal + Internationalization” dual-driven strategy, Junyuan has built a strong supply chain that ensures reliable delivery through ISO tanks and customized packaging solutions. The company’s efforts are also aligned with the high-level development of inland open economy pilot zones in China, while strengthening long-term cooperation with international partners.

A company spokesperson emphasized that exporting to Colombia is an important milestone in Junyuan’s international strategy. Looking ahead, Junyuan will continue to explore overseas market potential, expand export volumes, and enhance the global recognition of its brand concept — “Junyuan · More than n-Pentane.” By doing so, Junyuan Petroleum Group aims to bring more high-quality naphtha-based chemical products to the global stage and contribute to the growing recognition of Chinese manufacturing worldwide.
