Abstract
A fluid bed catalytic paraffin upgrading process is disclosed. By closely controlling catalyst particle size distribution and density, together with feedstock superficial vapor velocity, the fluid bed is maintained in a turbulent flow regime. Surprisingly, maintaining the fluid bed in a turbulent flow regime shifts the product selectivity away from methane and ethane and toward the more valuable products hydrogen, light olefins and C.sub.5 + gasoline. In the most preferred embodiment, the catalyst contains a dehydrogenation metal component such as gallium, zinc, platinum or rhenium to provide a C.sub.5+ gasoline product rich in aromatics. Catalysts useful in the inventive process include zeolites as well as layered siliceous materials.
