REACTOR FOR LIQUID-PHASE PROCESSES OF OXIDATION OF HYDROCARBONS Russian patent published in 2000 - IPC

FIELD: chemistry. SUBSTANCE: invention is related to chemical technology, namely, to reaction equipment of liquid-phase oxidation of hydrocarbons to organic mono- and polycarbon acids of aromatic and aliphatic series which are widely used in various branches of chemical industry. Reactor is made of vertical cylindrical body which internal space is divided by height with horizontal ring partitions with holes in center. Bubbling tube presenting vertical cylinder with conical expansion underneath in the form of funnel with perforated conical wall is put on lower ring partition in each section. Upper cut of bubbling tube is located above upper ring partition at distance that ensures circulation of liquid phase into section located above. Circulation tubes are presented in the form of ring clearance between babbling tube and wall of reactor body or in the form of separate cylindrical tubes enclosed in tube grates. The latter have shape of horizontal plates or truncated cone. Branch pipes to inject reagents are positioned at top of reactor and branch pipes to bring out reaction products are located at bottom. Air is injected into lower part of reactor and exhaust gases are removed from upper part of it. EFFECT: increased productivity of proposed reactor, enhanced output and quality of products. 3 dwg, 2 tbl
