REACTOR FOR DEHYDROGENATION OF PARAFFIN HYDROCARBONS C-C Russian patent published in 2016 - IPC B01J8/04 C07C5/333 

FIELD: petroleum chemistry.

SUBSTANCE: invention relates to petrochemistry, particularly, to reactors for dehydrogenation of paraffin hydrocarbons C₃-C₅ into corresponding olefin hydrocarbons. Reactor with fluidised bed of fine catalyst comprises a vertical cylindrical housing, raw material vapour inlet pipe connected with raw material distributor in lower part of reactor housing, pipes for outlet of contact gas, inlet and outlet of circulating catalyst, sectioning grids with free cross-section increasing on height of reactor, separating fluidised catalyst bed into sections, wherein between lower sectioning grid and distributor of raw material there is a damping grid, having free cross-sectional area greater than that of lower sectioning grid, and making up more than 25 and less than 90 % of section of housing, wherein distance from said grid to lower sectioning grid is 0.5-2.0 of height of section above lower sectioning grid.

EFFECT: higher efficiency of reactor and improved dehydrogenation.
