petrochemistry. SUBSTANCE: reactor for dehydration of C3-C5 paraffin hydrocarbons with fluidized bed of fine-grained catalyst has vertical cylindrical body, branch pipes for intake of raw material and discharge of contact gas, supply and discharge of circulating catalyst, stripping section, distributor of raw material above it and grates separating catalyst fluidized bed into sections. Grates have free section increasing in reactor height. Lower grate has free section amounting to 10-30% of body section, and upper grate, 20-60%. EFFECT: increased yield of olefin due to reactor operation efficiency. 11 cl, 5 dwg, 2 tbl, 8 ex
