Abstract (en)
[origin: WO2011009570A1] The invention relates to processes for dehydrating alkanes. In a plurality of reactors of the adiabatic, allothermic or isothermic type or combinations thereof, a gaseous alkane-containing stream of material is led through a bed of catalyst in a continuous operation, which produces a gas stream which contains an alkane, hydrogen and an unconverted alkane. In order to achieve equalization of the product composition, at least one of the process parameters comprising temperature, pressure or vapor-hydrocarbon ratio is registered at one or more points on at least one of the reactors in the form of measured values, at least one of the process parameters being monitored and influenced in a specific manner, so that the composition of the product gas at the outlet from the reactor remains constant over the operating period.
