But advantages areusually accompanied with disadvantages, in the case of hydrophilic fibrous ionexchangers it’s high hydraulic resistance of swollen material layer. High hydraulicresistance is hindering liquid-phase processes in traditional chemical reactors, thuslimiting industrial use of fibrous ion exchangers.We’ve designed and made pre-production model of reactor for processes withfibrous catalysts and sorbents. Assembled representation of developed catalyticreactor is depictured at Pic. 1: elevation drawing (vertical section) and vertical view(horizontal section). Reactor consists of body 1, upper and lower flanges 2,3 withrabbets for densifier 4. There are two diametrically opposite inlet nozzles 5 and 6 atthe lower part of the reactor. Outlet nozzle 7 is located in the center of the upperflange. Two porous pipes 8 and 9 were coaxially arranged inside body of catalyticreactor. Fibrous ion exchanger is placed between these pipes. Reactor body andpipes are gripped between upper and lower flanges with hanger bolts 10 and screwnuts 11. All reactor components, except for hanger bolts and screw nuts, are made ofpolymeric materials.Developed reactor was tested in the process of catalytic water deoxygenating [1].Fibrous anion exchanger with supported palladium was used as catalyst. Waterstream with dissolved hydrogen was injected in the reactor though inlet nozzles, thenwater radially passes through palladium supported fibrous catalyst placed betweenporous pipes. Deoxygenized water comes out from outlet nozzle. Overall result ofreactor and process tests was positive.433
