Abstract
A process for dehydration of an ethanol feed stream comprising sending said ethanol feed stream and steam to a radial flow reactor to contact a catalyst under reaction conditions and produce an effluent comprising ethylene. The use of a radial flow reactor eliminates concerns about pressure drops that may occur with conventional fixed bed downflow reactors.
Claims12
A process for dehydration of an ethanol feed stream comprising:
- mixing said ethanol feed stream with steam and feeding the ethanol feed stream and steam mixture to a charge heater to produce a heated charge stream;
- and
- sending said heated charge stream to a radial flow reactor to contact a catalyst under reaction conditions and produce an effluent comprising ethylene, wherein a pressure drop through a catalyst bed in the radial flow reactor is about 3 to about 5 psi.
