摘要

Proposed are a reactor and a method for assessing flaws in and optimizing the structure of a reactor for the dehydrogenation of С3-С5 paraffin hydrocarbons, having a fluidized bed of a finely divided catalyst, said reactor comprising a vertical cylindrical housing (1), gratings (3) with a free cross-section which increases with the height of the reactor, and connecting pipes (7), (6) which are mounted across the height of the housing (1) and are connected to instruments for measuring temperature and changes in pressure, wherein the free cross-section of the gratings (3) is determined by the relationship φi = φ1+A⋅expB⋅(hi/Hобщ), where φi is the free cross-section of the ith grating (in %); φ1 is the free cross-section of the bottom grating (in %); hi is the distance from a feedstock vapour distributor to the ith grating (in m); ехр is an exponential function; Нобщ is the total height of the fluidized catalyst bed in the reactor above the feedstock vapour distributor (in m); A is a coefficient equal to (0.5-15); B is a coefficient equal to (0.5-1.0); i is the grating position index. The technical result of the claimed invention is an increase in dehydrogenation indices (greater yields of olefins from the total feedstock and the reacted feedstock), a reduction in the amount of catalyst entrained from the reactor, and the development of reactor variants for the dehydrogenation of paraffin hydrocarbons and other fluidized bed processes.
