Inventors include Nakula Krishna R; Jaikesh S; Dr. Ramaraju H K; and Haseebuddin M R.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a system and method for the high-efficiency catalytic microwave-assisted pyrolysis (MAP) of polyolefin waste materials, specifically high-density polyethylene (HDPE), to selectively generate hydrogen-rich syngas while suppressing heavy wax formation. The system utilizes a custom composite susceptor-catalyst pellet matrix comprising silicon carbide (SiC), transition metal catalysts, and a carbonaceous binder configured to absorb 2.45 GHz microwave radiation rapidly and uniformly. The reactor features a sealed quartz reaction chamber disposed within an electromagnetically choked microwave cavity, an integrated inert gas purge routing, an inline condensation manifold for heavy wax separation, and a dual-path pressure-relieved gas collection assembly. The method provides precise volumetric heating, suppressing secondary tar formation and yielding a non-condensable gas fraction with enhanced hydrogen selectivity under atmospheric pressure.
