Smart Equipment Optimizes Production Efficiency: Two Invention Patents Enter Substantive Examination Phase

Oriental Energy has achieved significant milestones in its 10,000-ton carbon fiber Phase I project. The company's R&D team has innovatively designed two sets of key polymerization units, and the related invention patents have now entered the substantive examination phase.

The patents primarily focus on optimization of PAN (polyacrylonitrile) aqueous-phase polymerization equipment and its application methods, signifying a substantial elevation in the company's independent innovation capabilities within the carbon fiber industry.

Two innovative reactor designs have been developed in PAN precursor aqueous-phase polymerization, Among them, "A PAN Precursor Aqueous-Phase Polymerization Reactor and Its Application Method" (CN202410832300.X) adopts a synergistic design of multi-stage agitation and annular baffles, with an overall modular structure, achieving high-precision dynamic thermal regulation of polymerization heat for the first time. This improves reaction temperature uniformity by 40%, laying the foundation for producing highly homogeneous precursor fibers. "A PAN Precursor Aqueous-Phase Polymerization Termination Reactor" (CN202411235000.X) innovatively employs a hydraulic-lift split structure and planetary mixing system, enabling rapid disassembly, maintenance, and residue-free cleaning. This addresses the long-standing technical challenges of difficult equipment cleaning and material adhesion in conventional systems.

The above two patents entered the substantive examination phase on November 15, 2024, and January 24, 2025, respectively, and have been successfully applied to the company's ongoing 10,000-ton carbon fiber project.
