ABSTRACT:
A process and apparatus are disclosed for the catalytic conversion of hydrocarbons in a transport or sub-transport fluidized bed reaction zone. Inert particles are used to transfer heat to the reaction zone. The particles may be heated separately from the catalyst in a combustion zone or together with the catalyst in a regenerator. Fuel is fired to heat the inert particles or a mixture of catalyst and inert particles. Hydrogen deficient fuels such as charcoal or coke are preferred.
