ABSTRACT:
The present invention provides a method and apparatus for maintaining the active life of a catalyst in organic feed processing by applying a series of electromagnetic radiation pulses to the catalyst in a reactor. The pulsing of the catalyst selectively heats and cools the catalyst and can regulate the relative internal pressure of the catalyst particles to stimulate the acceleration of oil macromolecules mass-exchange through the catalyst pores and surface. This allows for the removal of cracked oil molecules from the particles. The application of electromagnetic pulses also regulates the activity of the catalyst. The electromagnetic radiation reduces the formation of coke on the catalyst and increases the life of the catalyst in the reactor. Further, the present invention provides a method and apparatus for removing water and salt from an organic feed. Water and salt is removed by applying a series of electromagnetic radiation pulses to the organic feed. A first pulse condenses water contained in the feed and induces salt to dissolve in the condensed water. A second pulse vaporizes a portion of the condensed water droplets to bring the droplets to the surface of the organic feed.
