Patent ID: 7070743

Claim:
An apparatus for conducting elevated temperature, gas phase, catalyzed chemical reactions for the preparation of HCN comprising: a reaction chamber defining a hollow cylinder comprised of a substantially gas-impermeable electrically non-conductive material, a catalyst/susceptor defining an electrically conductive and gas-permeable hollow cylinder positioned coaxially within said reaction chamber and comprised of one or more platinum group metals in a form selected from porous foam, or a filamentary structure comprising one or more of braided wire mesh, woven wire mesh, knitted wire fabric, bobbin-wound wire filaments or spirally-wound sock or sleeve, and an induction coil surrounding said catalyst/susceptor and energizable by a power source capable of supplying alternating current, whereby said catalyst/susceptor is heated by induction from an alternating magnetic field to a temperature sufficient to effect the chemical reaction.
