Indirect heating is achieved by direct heating of a fluid, such as a process flow, which in turn flows through the catalyst, thereby transferring heat to the catalyst. Additionally, the heating element 400 may be placed within a sheath that is brought into direct contact with the catalyst or fluid that flows through the catalyst. By these means, catalysts of many forms, including pellets, extrudates, spheres, and monoliths, may employ this catalyst heater 400. The catalyst heater 400 can be made of any resistive wire, cartridges, or rods that may be coupled to a power source to provide the energy to produce the heat.  <P>COPYRIGHT: (C)2008,JPO&INPIT
