Magnetic Nanobiocatalyst Reactor: Biodiesel from Enzyme-Coated Nanoparticles

Free lipase enzyme dissolved in an oil/methanol mix works fast but is thrown away with every batch. Anchor that same enzyme onto magnetic iron-oxide nanoparticles instead, and a nanoscale surface area boost keeps the reaction fast — while a magnet on the reactor wall pulls the whole nanocatalyst out afterward for reuse. This simulator renders a real stirred-tank reactor in 3D: triglyceride oil droplets convert into biodiesel (FAME) and glycerol on contact with enzyme-coated nanoparticles, temperature and stirring rate govern reaction kinetics through an Arrhenius rate law, and toggling the magnetic field visibly drags the ferromagnetic nanocatalyst to one wall for recovery. Run consecutive reaction cycles and watch recovery efficiency, residual enzyme activity, and cumulative biodiesel yield evolve exactly as they would in a real magnetically-recoverable nanobiocatalyst process.
