Multiphase Catalytic Packed-Bed Reactors

Multiphase caulytic packed-bed reactors are used in chtmid, petrocbemid, as well as in the petroleum Lndustrg for contactirrg gaseau and liquid reactaxzzs with 2 solid ucalyst. Xydrodesulfurszltion of petroleum fractions, liquid-phase catalytic hydrocracking, and brrryaadiol synthesis fmm forrmldehyde and acetylene (one of the main steps of the Reppe-Buna synthesu) am well-bwn mrrltipnase caralytic packed-bed pmcesses. Multpharse catalytic packed-oed reactom have also been used in liquid waste treazmens recemly. h the case of absoqzion followed by homogeneous catalyrlc reacsions LO the liquid phe. The Sxed bed is formed by inert packing which enables an inmnsiw mixing between the gas and liquid phases, and thus producar a large gas-liquad interface.
