Coker Gas Oil Denitrification

Non-hydrogenation complexation denitrification · Improves FCC feed quality · Basic nitrogen removal ≥80%

Three differentiated advantages that cannot be replicated

In an industry with fierce price competition, we choose to speak with technology and cases

🏭

Source manufacturer · Not an agent · Not a compound

The self-built Xiantao factory has 10+ enamel/stainless steel reaction synthesis kettles of different specifications, and independently synthesizes imidazoline monomers, with complete quality inspection records for each batch. Direct supply from the source factory means transparent prices, traceable quality, and stable batches.Understand the production strength of the source factory →

Proprietary synthesis technology · 13 national patents (3 invention, 10 utility model)

A team of more than 10 experts continues to deepen expertise in petrochemical corrosion protection, oil product denitrification, and sewage reuse. Independent processes and proprietary formulas—not simple blending.View patent list →

📊

20+ real cases · 10 third-party inspection reports

Large domestic refineries such as a CNPC refinery, Daxie Petrochemical, Jingmen Petrochemical, and Wuhan Petrochemical all have practical application cases. Test reports from third-party authoritative organizations can be provided, and the data speaks for itself before purchasing if qualified.

Some customer application cases

Based on state-owned refineries, cooperate and communicate with many intermediary customers for win-win results

Hongrun Petrochemical (Changyi · Qingzhou)
Coker Gas Oil Denitrification Agent

Low-acid-value denitrification of coker gas oil: basic nitrogen reduced from 1136/1585 μg/g to 429.8/772.5 μg/g at ~1.0-1.1% dosage.

Application report
