II 71A 174 112 113 Il 72, \ :-.A.2 / 7 3 71- (57) : Embodiments of the invention are directed to a device and a method for unloading particulate material from a reactor in tube of a catalytic reactor comprising an array of substantially vertically aligned reactor tubes. The device comprises an air lance (11, IN 111-113) for loosening the particulate material inside the reactor tube using pressurized air, an air lance unit (10) for feeding the air © lance in and out of the reactor tube, and a flexible guide tube (12, 121-123) on one end connectable to the air lance unit and on the 0 ---- other end connectable to a cleaned reactor tube (7, 71-73) for guiding the air lance from the reactor tube to the cleaned reactor tube for GO storing a part of the air lance that has not been fed into the reactor tube within the first cleaned reactor tube. 1-1 0 ei C [Continued on next page] WO 2018/007564 Al MIDEDIMOMOIDEIREIDIONIMMOIEHIMEMOIS (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
