The new electrified reactor uses magnetic induction to generate heat – the same sort of process used in induction stoves. Instead of having to transport heat through pipes, induction heating creates heat internally within the reactor, by taking advantage of interactions between electric currents and magnetic fields. If you wanted to inductively heat up a steel rod, for example, you could wrap a wire around it and run an alternating current through the coil.
“You’re heating a large surface area structure that is right next to the catalyst, so the heat you’re generating gets to the catalyst very quickly to drive the chemical reactions,” Fan said. “Plus, it’s simplifying everything. You’re not transferring heat from somewhere else and losing some along the way, you don’t have any pipes going in and out of the reactor – you can fully insulate it. This is ideal from an energy management and cost point of view.
