CPChem’s PAO manufacturing process utilizes a single flexible technology platform capable of producing a wide range of PAO grades. According to company patents and literature, the production platform accommodates different catalyst systems—including conventional Lewis acid (such as BF₃), and metallocene-based catalysts—to tailor polymer architectures and viscosities as market needs demand.
The project is integrated into CSPC’s Phase III expansion and targets commercial startup by 2028. NEXPAO brings proven quality and energy efficiency for premium synthetic lubricants, marking its first deployment in China’s booming chemicals market. Construction and auxiliary works are underway, reinforcing CSPC’s position as a specialty chemicals leader in Asia.
Just published a comprehensive technology review on the manufacturing process that transforms linear alpha olefins into polyalphaolefins - the backbone of today's high-performance synthetic lubricants.
Key highlights from the review:
✅ Complete process breakdown: from feedstock purification to hydrofinishing
✅ Catalyst systems comparison: BF₃ vs metallocene technologies
✅ Technology landscape: major players including Neste, CPChem, INEOS, ExxonMobil, Sinopec, PetroChina/CNPC, plus emerging technologies.
✅ Industrial considerations: economics, safety, and environmental aspects
1-Decenebasedpolyalphaolefins(PAOs) are synthetic hydrocarbon lubricant base oils produced through the oligomerization of 1-decene (C₁₀H₂₀) followed byhydrogenation. These PAOs represent the most commercially significant and widely used syntheticbase oilcategory, forming the backbone of the global PAO market due to their optimal balance of performance properties.
Polyalphaolefins (PAOs) are synthetic hydrocarbons produced through the oligomerization of linear alpha-olefins, primarily 1-decene, followed by hydrogenation to create fully saturated molecules with the molecular formula CₙH₂ₙ₊₂. PAOs are classified as API Group IV base oils, representing the most common synthetic base oil used in industrial and automotive lubricants.
