Abstract
A process for producing aromatic hydrocarbons from a light alkane feedstock such as an ethane-containing hydrocarbon stream is disclosed. The process comprises: contacting a light alkane feedstock comprising at least 50% ethane with a bi-functional aromatization catalyst in a fluidized bed reactor of bubbling or turbulent fluidization regime. The fluidized bed reactor comprise a catalyst bed, catalytic combustor and internal heat exchanger tubes embedded in the catalyst bed to provide the heat supply necessary for production of aromatic hydrocarbons. Continuous and uninterrupted production of aromatic hydrocarbons is realized by fluidly connecting multiple reactors in parallel and cycling operation of individual reactors between aromatics production mode and catalyst regeneration mode.
