FIELD: chemical or physical processes.
SUBSTANCE: invention relates to a method for catalytic dehydrogenation involving: mixing of the fluidised gas, which includes methane, natural gas, ethane, hydrogen, nitrogen or any combination thereof, with the stream of the fluidised catalyst in the section for fluidisation of the recycled catalyst of the reactor to form a stream of a recycled catalyst; flow of fluidised catalyst passed through catalytic dehydrogenation reactor and left catalyst separation zone; feeding part of stream of fluidised catalyst for catalyst regeneration; and recycling the recycled catalyst stream either directly or indirectly to the catalytic dehydrogenation reactor.
EFFECT: use of disclosed method enables to recycle dehydrogenation catalyst while maintaining its activity and selectivity.
