  • Catalytic hydrocarbon reformer with enhanced internal heat transfer mechanism
    Patent number: 5484577
    Abstract: A catalytic hydrocarbon reformer operates at lower temperature and pressure relative to conventional reformers. Convective heat transfer between the hot combustion gas stream and the reactor tube is enhanced through use of a narrow gap heat transfer area, which induces turbulent flow of the combustion gas stream across the reactor tube. The reactor tube includes a catalyst fines collection tube to accumulate and retain catalyst particles or fines entrained in the reformate gas stream.
