Abstract
The present invention relates to a method for dehydrogenating an alkane, the method including: a step of feeding into dehydrogenation reactors a feed gas stream containing a hydrocarbon to be dehydrogenated, hydrogen, and steam and performing dehydrogenation, wherein the dehydrogenation step is repeated in five or more sets, the dehydrogenation reactors have two parallel-connected reaction material heaters configured to heat the feed gas stream which is fed into each of the dehydrogenation reactors, and the steam is fed separately to the individual reactors for five or more sets of dehydrogenation steps; and a step of cooling and compressing a production gas stream resulting from the previous step, quenching the compressed product gas stream by passage through a cooling box, separating and purifying the product gas stream having passed through the cooling box, and recovering a product.
