An inclined baseplate for a radial bed reactor improves solids flow from the bottom of the reactor. Gas flow can be improved by utilizing an aerated baseplate or by providing a non-porous section of outer perforated cylinder in the area below the level of the bottom of the inner perforated cylinder.

Inclined baseplate in dehydrogenation reactor

The present invention relates to a process and apparatus for the production of light olefins comprising olefins having from 2 to 3 carbon atoms per molecule from a feedstock containing heavier olefins. An intermediate cut from a fractionation column is used as olefinic feed to an olefin cracking process preferably after undergoing selective hydrogenation of diolefins. In one embodiment, a liquid side draw from a fractionation column is selectively hydrogenated and then returned to the fractionation column from which a vapor side draw containing olefins is cracked in the olefin cracking reactor.

Apparatus and process for light olefin recovery

A process is disclosed for hydrotreating olefin-containing hydrocarbon streams for the purpose of producing very low olefin concentrations without the use of high pressure hydrotreating. The process is useful in preparing feeds to adsorptive separation zones. In the process the effluent of a hydrotreating reaction zone is passed into a stripping column. Preferably, substantially all liquid flowing downward through the lower section of the column is withdrawn and then passed through a hydrogenation reactor. The hydrogenation reactor effluent is passed into the bottom of the column to allow removal of dissolved hydrogen.
